single portrait/landscape but need to mirror specific direction.

Refer to issue #8867 for details and rational.
Convert sigset_t to an array type so that more than 32 signals can be supported.
Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
types,
Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).
This is is a work in progress; a draft PR that you are encouraged to comment on.
In the last change, the assert behavior test was not considered. Therefore, in this change, sync will be performed only when SYS_RESTART/SYS_DOWN situation occurs, avoiding unpredictable results caused by handling locks or semaphores in interrupts.
Calling syslog to print logs in clock_gettime will cause the system to have recursive output, i.e., clock_gettime->sinfo->syslog->clock_gettime, with the consequences of stack overflow or non-stop log output.
Some targets, such as qemu-rv support multiple architectures. The required flags need to passed to the linker when built "out-of-tree" in the application directory.

There are number problems with the implementation of realtime signals in NuttX as discussed in Issue #8869. A first step to correcting any of these is to correct the definitions of SIGRTMIN, SIGRTMAX, and RTSIG_SIX.
SIGRTMIN is the first real-time signals. Real-time signal numbers must not overlap the standard signal numbers. Before this fix, it was set equal to the first standard signal. Real-time signals differ from standard signals in that (1) they have no default actions, and (2) real time signal actions are prioritized whereas standard signal actions are processed FIFO.
SIGRTMAX is the last real-time signal.
RTSIG_MAX must be set equal to maximum number of realtime signals reserved for application use
The change corrects the definitons but has not impact at all becasuse none of there definitions are currently used in the OS. But they will be when prioritized real time signal handling is implemented.
arm-none-eabi-gcc 12.2.0 gives the following warnings:
error: 'primask' is used uninitialized
error: 'primask' may be used uninitialized
We use Werror and the file is indirectly included in different
places. I suggest telling the compiler to ignore these warnings
since primask is initialized on the first assembly line.
This is the only problem I encountered so far when upgrading the compiler.
SPI transfers are dynamically determined to use DMA or not.
The flag to judge is removed in a previous simple refactoring commit.
Revert the logic and fix an issue that SPI transfer fails.
1. Enable CONFIG_MMCSD_SDIOWAIT_WRCOMPLETE to use D0 Busy to detect Write Complete
2. Increase bcmf frame pool to 16
3. Increase NET_ETH_PKTSIZE to 1518 to compatible with net MTU
