Pointing to the documentation page doesn't make sense in this case,
because it doesn't explain the use of `#undef XXX` for this case anyway.

Add crc8rohcincr() function to support byte-by-byte CRC8 calculation
using the ROHC polynomial (0x07) without XOR inversions. This is
useful for protocols that require incremental CRC accumulation,
such as GSM 07.10 (CMUX), where the CRC must be computed as frames
are parsed from circular buffers.
Changes include:
- New crc8rohcincr() function for single-byte incremental CRC
- Function takes current CRC value and returns updated CRC
- Uses same g_crc8_tab table as other ROHC functions
- No XOR inversions applied for proper accumulation
This allows protocols like CMUX to replace local CRC table
implementations with standard libc CRC functions while maintaining
correct incremental calculation behavior.

Add support for pthread_{get|set}concurrency support.
NuttX uses 1:1 threading model (every pthread is a kernel-managed thread),
so this function has no real effect on the scheduling behavior.

This commit adds simple implementation of guardsize for pthreads.

Prior to this commit, it wasn't possible to load ELF modules from
the external PSRAM. There were two main issues about it: 1) copying
data using the instruction bus was being used instead of the data
bus (this, per si, isn't a problem, but requires special attention
regarding data alignment), and 2) the cache was not being properly
cleaned and flushed to properly access the loaded data using the
instruction bus.

1. Adopt an exponential backoff strategy () to dynamically adjust the timeout
duration, which is suitable for retry scenarios.
2. Optimize the default configuration to set the initial timeout to 5 seconds.
3. Support dynamic modification of the maximum timeout limit to adapt
to different scenarios.

This reverts commit 8f96e59aee.
The implementation of __dso_handle is independent of the HOST OS but dependent on the specific compiler.
Therefore, this patch will cause compilation failures for other cross-compilers on the Windows platform, such as arm-none-eabi-gcc and aarch64-none-elf-gcc.
Constraints should be applied to compiler target rather than compiler host.
idr_destroy() would loop over the removed and alloced
RB tree nodes freeing them but not removing them from
the trees. From the perspective of the RB tree those
nodes would remain valid, while in fact, they were free
memory, potentially reallocated for other purposes, or
otherwise overwritten by the allocator with metadata.
This would cause (seemingly random) memory corruption
crashes triggered by the RB tree code trying to access
link fields from the free'd nodes.
Fix that by removing the nodes before freeing them.

If atomic_try_cmpxchg_xxxx runs on LL/SC architectures (e.g.ARMv7,
ARMv8, RISC-V), the weak CAS expands to a single LDREX/STREX pair.
If the CPU takes an IRQ/FIQ/SVC between the two instructions,
hardware performs an implicit CLREX and the following STREX returns
1, therefore atomic_try_cmpxchg_xxxx return failure even though
*addr* still holds the expected value.
So let's retry atomic_try_cmpxchg_xxxx in this case.
