The halt operation may be causes the raw epread data segment lost, and
usb ep_queue can handle when the usb buffer is full. so remove the

Enable CONFIG_DEV_SIMPLE_ADDRENV for all the qemu configs that used
the virtio driver to fix compile error when use the NuttX implemented
metal io read/write operations.
Becasue up_addrenv_pa_to_va() and up_addrenv_va_to_pa() are not
implemented by default.

Openamp/libmetal's metal io operation used the atomic operation, but
in QEMU 8.1.2, the risc-v IO region is not allow to use atomic instruction
in SMP case.

The task files should consult the "spawn action" and "O_CLOEXEC flags"
to determine further whether the file should be duplicated.
This PR will further optimize file list duplicating to avoid the performance
regression caused by additional file operations.

Summary:
- Temporarily disables ARCH_HAVE_FORK for arm64 to address a crash issue,
as detailed in https://github.com/apache/nuttx/pull/9755.
- This is a precautionary measure until a more permanent solution is implemented.
Impact:
- Temporarily limits certain functionalities on arm64,
but necessary to ensure system stability.
Testing:
- Successfully tested on QEMU-8.1.2.
- Note: please apply the changes from https://github.com/apache/nuttx-apps/pull/1962.

This moves task / thread cancel point logic from the NuttX kernel into
libc, while the data needed by the cancel point logic is moved to TLS.
The change is an enabler to move user-space APIs to libc as well, for
a coherent user/kernel separation.

Some assertions in extreme cases will cause syslog to be unable to
output logs normally, so this PR will restore the input registers
into the array of last registers to ensure that we can also obtain
some important informations.

Summary:
- Fixes a linker issue in https://github.com/apache/nuttx/pull/8244 by disabling compiler optimization.
- Adjusts CONFIG_DEFAULT_TASK_STACKSIZE to 4096 to ensure proper functioning of cxxtest.
Impact:
- The changes may slightly affect performance due to disabled optimizations
but are necessary for cxxtest stability.
Testing:
- Successfully tested on QEMU-8.1.2 with arm gcc 12.3.Rel1,
confirming resolution of the linker issue and stable operation of cxxtest.

If the semaphore is shared, the holder has put its own mmapped address
to pholder->sem. This means we must switch to the holder's address
environment when going through the held semaphores list.
A better option would be to get the kernel mapped address for the
semaphore's physical page, but that mechanism is not functional yet.
This fixes a full system crash when CONFIG_PRIORITY_INHERITANCE=y and
CONFIG_BUILD_KERNEL=y and user makes shared semaphore via:
int semfd = shm_open("sem", O_CREAT | O_RDWR, 0666);
sem_t *sem = mmap(0, sizeof(sem_t), PROT_READ | PROT_WRITE, MAP_SHARED, semfd, 0);
Previous adjtime() implementation was limited to adjusting system
timer tick period. This commit reimplements the internals to use
a kernel watchdog timer. Platform-independent part of the code now
works also for adjusting hires RTC and tickless timer rate.
User code facing API is unchanged. Architecture code API has changed:
up_adj_timer_period() is replaced by up_adjtime().
Other improvements:
- Support query of remaining adjustment by passing NULL to first
argument of adjtime(). This matches Linux behavior.
- Improve resolution available for architecture driver, previously
limited to 1 microsecond per tick. Now 1 nanosecond per second.
In order to achieve better scalability, change the stride
from pixel mode to byte mode.For example, in the case of RGB888
mode with 466 pixels in width and a 4-byte aligned buffer,it is
only necessary to extend the buffer of one line from 1398 bytes
to 1400 bytes, instead of extending it to 1404 bytes.

These values are board-specific properties that must be known on the application side.
Until now, these values had to be hardcoded on the application side.
Summary:
- Upgraded to xpack-riscv-none-elf-gcc-12.3.0-2 to resolve symbol recognition
issues in riscv-none-elf-gdb, as reported in
https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/issues/22.
Impact:
- Expected to enhance toolchain stability with no negative side effects.
Testing:
- Verified with rv-virt:netnsh and rv-virt:netnsh64 configurations
