This patch addresses the potential issue of uninitialized elements in
the argument vector returned by `lwp_get_command_line_args()`. The
previous implementation could leave `argv` in an inconsistent state
if certain errors occurred, leading to possible undefined behavior.
Changes:
- Replaced `rt_malloc()` with `rt_calloc()` to ensure `argv` is properly initialized.
- Added a consistent error handling path using `goto error_exit` to handle memory allocation failures and string copy errors.
- Ensured `lwp_free_command_line_args()` is called before returning on error, preventing potential memory leaks.

* mmap2 failure handling
当传入一个非常大的地址时，offset会计算得到一个值，又因为传入的地址错误，rc会得到错误码，结合offset会得到一个很奇怪的值。
* Implementation of setpgrp
执行setpgrp会走到这一步，在执行getpgrp无法得到创建的group的值
* Modify the return method of mmap

Since the completion is used to sync with ISR mostly, we should set the
default semantic to ISR-safe. So most user will be happy and don't see
any weird behavior in their codes.
Changes:
- Added `rt_completion_wait_noisr` and
`rt_completion_wait_flags_noisr` functions in `completion.h`,
`completion_comm.c`, `completion_mp.c`, and `completion_up.c`.
- The new APIs allow waiting for completions in non-ISR contexts
while ensuring thread context safety.
- Existing documentation and comments were updated to clarify
usage contexts and emphasize restrictions on ISR usage.

Analysis: There is still an omission in the preprocessing control of
_control_rtc in 24b0a81 ("Add RT_USING_RTC conditional
compilation protection in ctimer.c")
Solution: Add RT_USING_RTC preprocessing control to missing
_control_rtc

Analysis: RT_USING_RTC preprocessing is used in 47cd52d ("修复不

rtdevice.h, as well as the implementation and call of _control_rtc,
but there are some omissions.
Solution: Add RT_USING_RTC preprocessing control to missing

[components][lwp]fix exec and mount error code
|
|
This patch focuses on the ARM64 general context handling code.
The modifications are aimed at enhancing performance by simplifying
context save/restore operations.
Changes include:
- Adjusted stack alignment in `arch_set_thread_context` function.
- Updated `lwp_gcc.S` to reset frame pointer and link register.
- Refined `rt_hw_backtrace_frame_unwind` to handle user space address checks.
- Added `GET_THREAD_SELF` macro in `asm-generic.h`.
- Simplified context saving/restoring in `context_gcc.h` and related files.
- Optimized `rt_hw_context_switch_interrupt` and related assembly routines.

[dfs] feat: Mark dirty on unmap for shared mapping
This patch optimizes the pcache varea management by refining the
conditions under which pages are marked dirty, specifically targeting
the unmap operations in the dfs_pcache component. These changes were
necessary to enhance the efficiency of page cache management.
Changes:
- Adjusted include statements in `dfs_pcache.c` for better organization.
- Modified `dfs_aspace_unmap` function:
- Added a check to ensure `varea` is not privately locked before marking a page as dirty.
- Updated `dfs_aspace_page_unmap` function:
- Added a similar check for `varea` lock status before marking a page as dirty.
