* libs/libc/stdlib/lib_strtod.c:
(strtod): Add a note about limitations of this implementation
as compared to POSIX in the function's docstring. Also fix a
typo.
* libs/libc/stdlib/lib_strtof.c:
(strtof): Port the changes made to strtod in PR-6952 (commit
c83985c5ce) and add same note as above to docstring.
* libs/libc/stdlib/lib_strtold.c:
(strtold): Same changes as strtof.
g_dns_servers need init before dns_query, Otherwise sim can not add default
dns server when use usrsock mode to share host network.
Avoid similar problems in the future, so directly initialize g_dns_servers.

Summary:
- I noticed that adb shell failed when sh is spawned.
- Finally, I found that an error happened when executing dup2() action
if the file descriptor has the O_CLOEXEC option.
- This commit fixes this issue by dropping the option in the API.
Impact:
- posix_spawn_file_actions_adddup2() only
Testing:
- adbd with sabre-6quad:netnsh (will be merged later)

some toolchain provider remove const qualifier from global_impure_ptr
(e.g. Espressif) but other provider keep it(e.g. ARM or Cadence), so
let's define const to empty macro to pass the compile and more safety.

* libs/libc/misc/lib_getrandom.c, in function getrandom():
We were assigning the return value of _NX_READ() to nbytes, a
variable of the unsigned type size_t. Note that _NX_READ() resolves
to either read() or nx_read(), both of which return the signed type
ssize_t to indicate either the number of bytes read successfully
(>= 0) or an error (< 0). Then we were testing for a negative
size_t value, a condition that can never occur. The end result is
that if an error occured in _NX_READ(), it would never be detected
and getrandom() would return some large positive value. This bug is
corrected by assigning the return value of _NX_READ() to a new local
variable, ret, of size ssize_t.
The "p" format specifier already prepends the pointer address with
"0x" when printing.

Make use of XCHG/BSWAP on x86, REV16 and REV on ARMv6-m and above,
and whatever other optimized instructions on other platforms.
Defines extra CONFIG variables, and removes the unused functions for
endian-swapping. Fixes some oversights in using the macros.
