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.

Previously sigpending() returned all pending signals in the group, which is not
POSIX compliant. It should return signals pending only for the caller, so
a signal send with pthread_kill() intended for another thread should not be
returned (it's not pending for a caller).
This fixes the pthread_create.c/test9 test case from
PSE52 Open Group Threads Test Suite.

Many different architectures re-implemented the exact same code for
`up_*delay` because it was originally written as architecture dependent
code. Busy-waiting can be done regardless of architecture, so this
commit moves that duplicated implementation to a common file with weak
definitions so that individual architectures (see tc32) are still able
to override the definition if needed/desired.
Default implementation is not included if ARCH_TIMER is enabled, since
it is more accurate and provides its own weak definitions to override.

Introduce a new CI test to validate out-of-tree builds
and prevent regressions in the `make export` workflow.
Specifically, this change adds `test-oot-build.sh` that:
* Builds NuttX using a selected configuration.
* Runs `make export` to generate the export package.
* Copies the `nuttx-export` to the OOT build project.
* Verifies that compilation and linking succeed.

Added stopifstarted and startifstopped for setting watchdogs and other bits. Added adc_reset_dma, which must be run after stopping conversions in circular mode, because buffer and conversions become misaligned. Other refinements.
