Found a place in getopt_common() where the option string is used before it is checked if it is NULL. This can happen because the short option string is optional for getopt_long() and getopt_long_only()
If optstring is NULL, that would be an ERROR for getopt(), but not for the getopt_long() versions.
Should effect only the getopt() APIs
Tested on the simulator using apps/testing/ostest.

1. Null pointer dereference:
- for (ndx = 0; longopts[ndx].name[0] != '\0'; ndx++)
+ for (ndx = 0; longopts[ndx].name != NULL; ndx++)
2. Handle single character long options. An option like -x could be either a short option or a long option (under getopt_long_only()). This case was not being handled correctly.
3. Add missing support for optional arguments to short options (indicated with two "::"
This effects all members of the getopt() family of APIs.
Tested on the simulator using extensions to apps/testing/ostest.
Add implementations of getopt_long() and getopt_long_only()
There could be impacts to getop() since that implementation is shared withe new getopts_long() and getops_long_only() implementation.
Tested using a modified version of sim:nsh

getopt() in the FLAT build environment is not thread safe. This is because global variables that are process-specific in Unix are truly global in the FLAT build. Moving the getopt() variables into TLS resolves this issue.
No side-effects are expected other than to getopt()

Stream buffer flags has a dependency with allocated buffer,
and it cannot clear without buffer operation.
Change clearerr to keep buffer flags to prevent unexpected
buffer operation.
When CONFIG_SYMTAB_ORDEREDBYNAME is selected most code will use
the ordered search function. When it is not selected no code will
use the ordered search function. This change merges the two
functions and varies its behaviour based on the config setting,
such that all callers can simply call the one search function
and get the best behaviour.
An additional configuration option allows leading underscores to
be stripped from symbols being relocated in loaded objects. This
allows toolchains which prefix C symbol with underscores to make
loadable ELF objects.
Implement si_send/sendto/recvfrom with si_sendmsg/recvmsg, instead of
the other way round.

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
configuration changes.
