Piyush Patle 0dccc8ba21 include/debug.h: Move to include/nuttx/debug.h
debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.

A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

hujun5 6e8ae12ef1 pthread: make PTHREAD_MUTEX_DEFAULT_UNSAFE default true
Change the default pthread mutex robustness from ROBUST to UNSAFE when
CONFIG_PTHREAD_MUTEX_BOTH is enabled. This reflects the practical default
and allows removal of tracking code for non-robust mutexes, improving
performance and reducing memory overhead.

hujun5 082a3d3085 pthread: remove tl_lock
This lock is currently used in three places,
mainly to protect tls->tl_mhead. Among them,
pthread_mutex_add and pthread_mutex_remove involve
writing to tls->tl_mhead, and there is
certainly no conflict within the same thread.
As for pthread_mutex_inconsistent, it involves reading. Currently,
it can only be called when the TCB task corresponding to
this tls exits, and the TCB corresponding to the
tls can no longer continue to run.
It seems that adding the lock serves no real purpose.

hujun5 217e685beb pthread: move pthread_cond to userspace
Move pthread condition variable implementation from kernel (sched/pthread)
to userspace library (libs/libc/pthread). This allows userspace to handle
condition variable operations directly, reducing syscall overhead and
improving performance for pthread applications.

hujun5 5051721298 sched/pthread: move pthread mutex from syscall to user-space
Move pthread mutex operations from kernel-space syscall
interface to user-space implementations
to reduce syscall overhead. Relocate mutex holder list
tracking from task control block (tcb) to
thread local storage (tls) to improve memory layout and
cache efficiency. Add helper macros for
conditional mutex implementations and update syscall
interface accordingly.

guoshichao 4ce802900f pthead: change the pthread_equal implementation from macro to function

Huang Qi cfd0cc0d1a Remove duplicate includes across multiple files
This commit cleans up redundant header file includes throughout the codebase.
 The changes include:

 - Removing duplicate #include directives that were present in the same file
 - Consolidating includes that were split across multiple lines unnecessarily
 - Removing unused includes that were no longer needed
 - Fixing some formatting issues with includes

 The changes improve code organization and maintainability by:
 - Reducing unnecessary dependencies
 - Making include dependencies more explicit
 - Following consistent include patterns
 - Removing dead code

 No functional changes are made - this is purely a code cleanup commit.

chao an 6ee9ec7656 build: add initial cmake build system
1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)

------------------

How to test

From within nuttx/. Configure:

cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja

(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja

This uses ninja generator (install with sudo apt install ninja-build). To build:

$ cmake --build build

menuconfig:

$ cmake --build build -t menuconfig

--------------------------

2. cmake/build: reformat the cmake style by cmake-format

https://github.com/cheshirekow/cmake_format

$ pip install cmakelang

$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
