* 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.
For CONFIG_BUILD_KERNEL using the sched/task/task_exithook implementation
will just not work. It calls user code with kernel privileges which is
a bit of a security issue.
Targets build during the kernel phase did not have their dependencies
specified and thus they were not rebuilt after their dependencies have
changed, for example by changing options in menuconfig.

Summary:
- This commit adds R_RISCV_JAL support to arch_elf.c
- The code only checks the immediate value but does not relocate it
because it is done by the compiler.
Impact:
- None

- Tested with rv-virt:knsh64 (not merged yet)

Do not call strlen() here. Old implementation iterated
over string twice, if searched for position was at the
beginning. This commit changes strrchr() to scan string
only once, regardless of input.

Summary:
- Cast to unsigned char for strcmp and strncmp
- strcmp and strncmp are described following by opengroup.org
The sign of a non-zero return value shall be determined by the sign
of the difference between the values of the first pair of bytes
(both interpreted as type unsigned char) that differ in the strings
being compared.
