fix(newlib): usleep returning early
...
This commit updates usleep() to always sleep for the required sleep
period or more. This fixes a bug where the usleep() could sleep for less
than the request sleep period.
Closes https://github.com/espressif/esp-idf/pull/15132

feat(newlib): riscv: add CONFIG_LIBC_OPTIMIZED_MISALIGNED_ACCESS config option
...
This option replaces implementations of functions from ROM:
- memcpy
- memcmp
- memmove
- str[n]cpy
- str[n]cmp
The functions used in the firmware will be better optimized for misaligned
memory. Here are some measurements in CPU cycles for 4096-byte buffers:
memcpy: 28676 -> 4128
memcmp: 49147 -> 14259
memmove: 33896 -> 8086
strcpy: 32771 -> 17313
strcmp: 32775 -> 13191

fix(newlib): add missing __atomic_test_and_set for RISCV chips wo 'a' extension
...
Before the change described in
https://gcc.gnu.org/pipermail/gcc-patches/2023-September/631393.html it
appeared that inlining built-in GCC function __atomic_test_and_set() was
incorrect. It resulted in a non-atomic write.
After the change now present in GCC, the IDF should include the function
__atomic_test_and_set() to successfully link the final binary.
