Fix a problem where the log function would loop infinitely by
calculation error when a specific value was passed. For example,
in the following case, the log function loops infinitely and
never returns. So, this commit fixes to return the right value.
double a = 7883961.5;
double b = log(a);

I not two problems in handling of the return error values in PR #3858:
1. In KERNEL mode, the error return value of _SEM_WAIT() will be a negated errno value; in all other modes, it will be -1 (ERROR) with the errno variable set. This must be handled in the test of the returned value: Don't compare with -1; rather check if < 0
2. Also, conversion of the returned value to a negated errno value must be handled differently. This is handled by replacing -get_errno() with the macro _ERRVAL(ret)
This effects only error handling (it fixes it) and no other impacts are expected.
It's better to save one argument by returning pid directly.
This change also follow the convention of task_create.
BTW, it is reasonable to adjust the function prototype a
little bit from both implementation and consistency since
task_spawn is NuttX specific API.

OS functions in syscall.csv are ordered alphabetically. However, two recently added functions are not in the correct location. This PR simply corrects that ordering.
The ordering of one entry was also corrected in libs/libc/libc.csv. Same issue.
This change is only cosmetic.

I've seen a module with 16 bytes .rodata alignment for xmm operations.
It was getting SEGV on sim/Linux because of the alignment issue.
The same module binary seems working fine after applying this patch.
Also, tested on sim/macOS and esp32 on qemu,
using a module with an artificially large alignment. (64 bytes)
Fix comment in libs/libc/tls/tls_getinfo.c: The TLS data must lie at the beginning of the allocated stack memory for both push-up and push-down stacks.

Per the Linux man page, "By default, getopt() permutes the contents of argv as it scans, so that eventually all the nonoptions are at the end." This behavior, however, is not implemented in the NuttX getopt() logic.
The Linux man page requires that the getopt_long() and getopt_long_only() functions accept arguments to options in a form like:
--option=argument
This PR adds that missing functionality.
This change effects only getopt_long() and getopt_long_only()
Tested on a simulator NSH configuration with a modified version of the getopt() test in apps/testing/ostest.
If an unrecognized long option is encountered, we must skip over that argv[] entry or getopt_long() will seriously misbehave.
Affects getopt_long() and getopt_long_only()
Problem found and fix verified with an updated version of the OS test.
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.
Several licenses were missed in the initial work

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.

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.
