1f5786f5ea libc/stdlib: Fix range check in strtoul(l) 
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.

e160bffe28 Remove all fclose with stdin, stdout and stderr 
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.

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.

c11c1dc8fd libs/libc/stdio: replace double_t to double 
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'.

34b34e2d45 Fix: ensure archive files do not carry object files from prior builds 
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
configuration changes.

00933cfece sched/sched: Add sched_get_stackinfo() 
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.
