Major enhancements to LTP build system: - Split CMakeLists.txt into shared/posix/kernel sections with unified blacklisting - Add header stubs (linux/*.h, asm/*.h, lapi/*.h) for kernel test dependencies - Implement syscalls.h generation via regen.sh for NuttX syscall mapping - Define feature macros (HAVE_*, UNIT_TEST) and compiler flags for kernel tests - Resolve naming conflicts (safe_* functions) with macro renaming This enables LTP kernel test execution on NuttX, covering syscalls, filesystem, device drivers, and scheduler tests.

Define the complete loop_info structure and LOOP_* ioctl command constants in testing/ltp/include/linux/loop.h, matching Linux kernel's loop device interface. This allows LTP loop device testcases to build and execute when NuttX loop device support (CONFIG_DEV_LOOP) is available. Signed-off-by: guoshichao <guoshichao@xiaomi.com>
For the NuttX platform, the system call numbers themselves are independent of the architecture(arm/x86/risc-v). Therefore, there is no need to consider the differences between different architectures(arm/x86/risc-v). As a result, we can directly maintain them manually instead of relying on the regen.sh script to generate them dynamically. This makes it easier for maintenance, upgrading, and modification.

for kernel testcases that using main() method to execute, when invoke tst_exit() on execute finished, will report " executed from newlib!" error, this is caused by two kinds kernel testcases are forbidded linked together, in Linux this is OK, but for NuttX, this is necssary, so we choose to modify the NO_NEWLIB_ASSERT macro's implementation, thus to make kernel testcases can work in NuttX Signed-off-by: guoshichao <guoshichao@xiaomi.com>

Summary
Extend LTP (Linux Test Project) support on NuttX to enable compilation and execution of Linux kernel testcases, adding necessary infrastructure for kernel‑level API validation:
struct loop_infoandLOOP_* ioctlconstants intesting/ltp/include/linux/loop.h, allowing LTP loop‑device testcases to build and run whenCONFIG_DEV_LOOP=y.CMakeinfrastructure with proper header stubs,syscall mapping, and feature configuration to support kernel‑level test execution.Impact
