The previous implementation of strtoul(l) is flawed. The range check
assumed that when overflow happens, the truncated value is smaller than
the original value. As a counter example, passing "10000000000" to
strtol will not trigger ERANGE, but return a truncated value. This patch
adds more accurate range checks.

since it is wrong to close the builtin stream and specially note
https://pubs.opengroup.org/onlinepubs/9699919799/functions/fclose.html:
Since after the call to fclose() any use of stream results in
undefined behavior, fclose() should not be used on stdin, stdout,
or stderr except immediately before process termination (see XBD
Process Termination), so as to avoid triggering undefined behavior
in other standard interfaces that rely on these streams. If there
are any atexit() handlers registered by the application, such a
call to fclose() should not occur until the last handler is
finishing. Once fclose() has been used to close stdin, stdout, or
stderr, there is no standard way to reopen any of these streams.
and it is also unnecessary because the stream always get flushed.

Endian-ness issues are mind boggling sometimes. I have been confused by the logic in inet_ntop() a few times so I thought I would add some comments so that I (and others) will understand the endian-ness issues in the future. No change to logic, only comments changed.
Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c. gettid() is a dumb wrapper around getpid(). It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid(). Instead, move gettid() in the C library where it calls the single sysgtem call, getpid(). Much cleaner.

Modify reason:
When build Nuttx SIM, in x86_64 system:
Compile with gcc option '-m64' (default):
sizeof(double_t) = 8
sizeof(double) = 8
Compile with gcc option '-mx32':
sizeof(double_t) = 8
sizeof(double) = 8
Compile with gcc option '-m32':
sizeof(double_t) = 12 // long double
sizeof(double) = 8
When use '-m32', and print sth. like this:
printf("%f\n", (double)3.0);
SIM will print out: nan
This is because sizeof(double_t) is not equal with double.
Resolve:
replace all double_t to double in libs/libc/stdio.
As a user of '-m32', you should know double_t is one type
long double, and len is 12. And you use use '%lf' to print.
like:
printf("%lf\n", (double_t)3.0);
Currently we don't support '%lf'.

In some cases, when NuttX configuration changes and this makes the
object list used to build one of the .a libraries change as well,
since the command used to build it is "ar crs" and this simply appends
the list of object files, the library could still include object
files from prior builds. This commit modifies the ARCHIVE macro to
erase the .a file if it already exists.
Since in some cases this behavior was actually expected (object
files from a subdirectory were appended to a library created one
level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
This change should greatly improve behavior of building after

Functions within the OS must never set the errno value. fs_fdopen() was setting the errno value. Now, after some parameter changes, it reports errors via a negated errno integer return value as do most all other internal OS functions.
It's better to have a default working for many cases.
Usually DNS servers are not optimized for embedded clients.
Users can fine tune for their environment anyway.
1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread.
2. Remove pthread-specific data functions from syscalls.
3. Implement tls_alloc() and tls_free() with system calls.
4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free().
5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()
- Remove per-thread errno from the TCB structure (pterrno)
- Remove get_errno() and set_errno() as functions. The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode).
- Add errno value to the tls_info_s structure definitions
- Move sched/errno to libs/libc/errno. Replace old TCB access to the errno with TLS access to the errno.
Move the logic to get TLS information from an inline function to a normal function. For the unaligned case, it is probably too large to be inlined.
Also fixes some minor things from review of previous commits.
CONFIG_TLS_ALIGNED will select the (legacy) aligned stack implementation of TLS. If CONFIG_TLS_ALIGNED is not defined, then the new, implementation of TLS using an unaligned stack will be enabled.
The new OS interface, sched_get_stackinfo() combines two pthread-specific interfaces into a single generic interface. The existing pthread_get_stackaddr_np() and pthread_get_stacksize_np() are moved from sched/pthread to libs/libc/pthread.
There are two motivations for this change: First, it reduces the number of system calls. Secondly, it adds a common hook that is going to used for a future implementation of TLS.
Align the generated files name, so make distclean could also remove all nxfonts_bitmaps_*.c files, no

This commit resolves issue #620:
Remove CONFIG_CAN_PASS_STRUCTS #620
The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:
#ifdef CONFIG_CAN_PASS_STRUCTS
struct mallinfo mallinfo(void);
#else
int mallinfo(FAR struct mallinfo *info);
#endif
And even leads to violation of a few POSIX interfaces like:
#ifdef CONFIG_CAN_PASS_STRUCTS
int sigqueue(int pid, int signo, union sigval value);
#else
int sigqueue(int pid, int signo, FAR void *sival_ptr);
#endif
This breaks the 1st INVIOLABLES rule:
Strict POSIX compliance
-----------------------
o Strict conformance to the portable standard OS interface as defined at
OpenGroup.org.
o A deeply embedded system requires some special support. Special
support must be minimized.
o The portable interface must never be compromised only for the sake of
expediency.
o Expediency or even improved performance are not justifications for
violation of the strict POSIX interface
Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132
NOTE: This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.

The MOVEOBJ definition was used to work around the case where the object output of a compile or assemble is in a different directory than the source file. The ZDS-II tools have no command line option to perform this move; MOVEOBJ handled the move as a post-compiler operation.
MOVEOBJ is no longer needed because this the ez80 COMPILE and ASSEMBLE definitions now handle all of the object file movement cases.

task_spawn() and posix_spawn() are NuttX OS interfaces. In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call. Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters. Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
*
In order to support builtin in function in protected mode, a task_spawn() system call must be supported. Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters. This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures. Better to get more creative.
Squashed commit of the following:
Correct some additional compile-related issues.
Move include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h. Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.
Move binfmt/libbuiltin to libs/libc/builtin. There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.
Provided changes add option (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of available functions and syscalls automatically. The symbolic table is generated in form libsymtab.a which can be reused by application or directly pull in when "g_symtab" and "g_nsymbols" variables are requested by EXECFUNCS configuration.
I have tried to follow mechanisms for library compilation in different kernel protection modes but tested only flat no-MMU build. The basic assumption is that this library and libraries providing syscall stubs and C-library functions are available in user-space context and initial application (usually NSH) registers the symbol table through IOCTL. The table can be reused then by another applications in their address space as kernel allows. Simple for flat or protected mode, I am not sure if really support in MMU mode. It is highly probable that I have made some mistake, overlooked something, but functionality is optional (should not cause troubles in any mode if disabled) and main purpose is to lower memory overhead when more applications are loaded on memory constrained system which usually use direct kernel calling without protection or address space separation. If the table should be provided by kernel to applications then makefiles has to be adjusted.
The legacy '/' delimiter is still supported but not recommend and not advertised.
Squashed commit of the following:
Update configurations instructions in more README.txt files to show ':' delimiter vs '/' delimiter.
Update configurations instructions in various README.txt file to show ':' delimiter vs '/' delimiter.
tools: Update all configuration-related tools to accept ':' separator between board and configuration name.
Squashed commit of the following:
Last minute clean-up
libs/libc/grp/lib_find_grpfile.c: Fix some problems found in testing.
libs/libc/pwd: Finishes off implementation using /etc/passwd.
libs/libc/grp: Finishes off implementation using /etc/group.
libs/libc/pwd/lib_find_pwdfile.c: Add logic to look up user information in /etc/passwd file, if available.
libs/libc/grp/lib_find_grpfile.c: Add logic to look up group information in /etc/group file, if available.
Added stubbed implementations of getpwuid, getpwuid_r, getpwnam, and
getpwnam_r. These functions are essentially stubs pretending that NuttX
supported users and that the only configured user in the system was 'root'
with uid 0. The intend is not to provide meaningful new features, but to ease
porting of foreign source code to NuttX.
- Added an alphasort implementation
- Added a scandir implementation
- Added DT_* literals to include/dirent.h: Apparently those are not required by POSIX, but are part of 4.3BSD and available in glibc as well.
libs/libc/misc/Make.defs: For platforms whose CPP tool does not support a variable number arguments to pre-processor macros, we may still need to build the debug functions even when CONFIG_DEBUG_FEATURES is not selected. For example, __alert() may be needed is CONFIG_ARCH_STACKDUMP is set.
configs/makerlisp: Add an sdboot configuration that will load .hex files from the SD card.
Squashed commit of the following:
configs/makerlisp: Update comments about use of serial console.
configs/makerlisp: Add LED support, remove vestiges of button support (the board has no user buttons). Add support for SPI-based MMC/SD card slot.
arch/z80/src/ez80: Fix some link problems.
libs/libc/syslog/lib_syslog.c: The ZDS-II toolchain does not declare va_coy in stdarg.h. I think that the use of va_copy in vsyslog() is no necessary.
configs/makerlisp: Initial configuration directories cloned from ez80f910200zco with little more than naming changes.
