5d7f2fdf16 Fix loading of ET_DYN type of shared objects
* build-globals.sh
  - Only look in the nuttx for external symbols used when loading
    dynamic shared objects

* include/elf64.h
  - Correct the type of fields in the Elf64_Phdr structure

* libs/libc/dlfcn/lib_dlclose.c
  - Distinguish between ET_DYN and other objects as the former
    has both text and data in a single allocation to reserve
    GOT offsets

* libs/libc/dlfcn/lib_dlopen.c
  - Code formatting

* libs/libc/modlib/modlib_bind.c
  - Distinguish between relocation entry sizes by section type
  - Handle RELA style relocations

* libs/libc/modlib/modlib_globals.S
  - Formatting fixes
  - Symbols should not be weak - they exist or they don't

* include/nuttx/lib/modlib.h
  - Add an inidcator to module_s to distinguish between ET_DYN and other

* libs/libc/modlib/modlib_load.c
  - ET_DYN objects need to keep the relative displacement between the text
    and data sections due to GOT references from the former to the latter.
    This also implies that linking may require modification from the default
    for the shared objects being produced. For example, default alignment may
    mean nearly 64K of wasted space.

* libs/libc/modlib/modlib_unload.c
  sched/module/mod_rmmod.c
  - Distingusih between freeing of ET_DYN storage and other as the former
    is a single allocation.

* libs/libc/modlib/mod_insmod.c
  - Cater for ET_DYN objects having init and preinit sections

c178fa3260 stdio/lib_libfread: Fix buffer overflow issue
If the gulp size in the stdio buffer the remaining user buffer size it will:
- Corrupt memory in dest (user memory) and
- Keep corrupting KERNEL memory via the stdio character buffer until the
  whole system crashes, as the 'remaining' count underflows

This patch fixes this behavior.

9f10ddc9b0 nuttx/build: Restore ARLOCK to improve compile speed in incremental case
To solve the issue of carrying object files from previous builds,
Matias changed the archiving process to re-archive libapps.a on every compilation,
if libapps.a carries more object files, incremental compilation will waste too
many time in re-archiving, compared with the previous implement, this is a degradation
of the build system.  Referring to mature engineering projects such as cmake, if there
is configuration or source file changed, the best solution should be to reconfigure
the environment.

Revert this PR to ensure the compilation speed during incremental compilation.

|  commit 34b34e2d45 (tag: nuttx-20200914-172150)
|  Author: Matias N <matias@protobits.dev>
|  Date:   Fri Sep 11 22:31:38 2020 -0300
|
|      Fix: ensure archive files do not carry object files from prior builds
|
|      In some cases, when NuttX configuration changes and this makes the
|      object list used to build one of the .a libraries change as well,
|      since the command used to build it is "ar crs" and this simply appends
|      the list of object files, the library could still include object
|      files from prior builds. This commit modifies the ARCHIVE macro to
|      erase the .a file if it already exists.
|
|      Since in some cases this behavior was actually expected (object
|      files from a subdirectory were appended to a library created one
|      level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
|
|      This change should greatly improve behavior of building after
|      configuration changes.

Since nuttx has already implemented SSP related hook functions,
so in this PR, we filter out this option in the link phase to ensure that

2a5f48c3fd libs/libc/stdlib: fix strtoul,strtoull bugs when value outside range
Prototype:
  unsigned long strtoul(FAR const char *nptr, FAR char **endptr, int base);
  unsigned long long strtoull(FAR const char *nptr,  FAR char **endptr, int base);

If endptr is not NULL, strtoul()/strtoull() should store the address of the first
invalid character in *endptr. And if the correct value is outside the range of
representable values, {ULONG_MAX} or {ULLONG_MAX} shall be returned and errno set
to [ERANGE].

With such code:
  strtoul("34592348345343453453455645765736575865767", &endptr, 10);

It indeed returns ULONG_MAX and sets errno to ERANGE. But after strtoul
return, endptr points to "3455645765736575865767", not NULL.

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

8868c58720 Fix Deadloop in VFS if CONFIG_CANCELLATION_POINTS is enabled
If cancellation points are enabled, then the following logic is activated in sem_wait().  This causes ECANCELED to be returned every time that sem_wait is called.

    int sem_wait(FAR sem_t *sem)
    {
      ...

      /* sem_wait() is a cancellation point */

      if (enter_cancellation_point())
        {
    #ifdef CONFIG_CANCELLATION_POINTS
          /* If there is a pending cancellation, then do not perform
           * the wait.  Exit now with ECANCELED.
           */

          errcode = ECANCELED;
          goto errout_with_cancelpt;
    #endif
        }
      ...

Normally this works fine.  sem_wait() is the OS API called by the application and will cancel the thread just before it returns to the application.  Since it is cancellation point, it should never be called from within the OS.

There there is is one perverse cases where sem_wait() may be nested within another cancellation point.  If open() is called, it will attempt to lock a VFS data structure and will eventually call nxmutex_lock().  nxmutex_lock() waits on a semaphore:

   int nxmutex_lock(FAR mutex_t *mutex)
   {
     ...

     for (; ; )
       {
         /* Take the semaphore (perhaps waiting) */

         ret = _SEM_WAIT(&mutex->sem);
         if (ret >= 0)
           {
             mutex->holder = _SCHED_GETTID();
             break;
           }

         ret = _SEM_ERRVAL(ret);
         if (ret != -EINTR && ret != -ECANCELED)
           {
             break;
           }
       }
   ...
}

In the FLAT build, _SEM_WAIT expands to sem_wait().  That causes the error in the logic:  It should always expand to nxsem_wait().  That is because sem_wait() is cancellation point and should never be called from with the OS or the C library internally.

The failure occurs because the cancellation point logic in sem_wait() returns -ECANCELED (via _SEM_ERRVAL) because sem_wait() is nested; it needs to return the -ECANCELED error to the outermost cancellation point which is open() in this case.  Returning -ECANCELED then causes an infinite loop to occur in nxmutex_lock().

The correct behavior in this case is to call nxsem_wait() instead of sem_wait().  nxsem_wait() is identical to sem_wait() except that it is not a cancelation point.  It will return -ECANCELED if the thread is canceled, but only once.  So no infinite loop results.

In addition, an nxsem_wait() system call was added to support the call from nxmutex_lock().

This resolves Issue #9695

af53d7a178 libs/libc/aio/lio_listio: fix the heap use-after-free bug
1. the lio_sigsetup() method use a universal sighand instance across all
aiocb instances, but inside the lio_sighandler() method, if one aiocb is
handle finished, then this method will free the sighand instance that
come along with current aiocb instance. thus when handle next aiocb
instance, use-after-free crash will happen. in order to solve this
problem, we make each aiocb instance have their own sighand instance

8fe8417ffb libc/fdcheck: add fdcheck module
In embedded development environments, due to the lack of address isolation between processes,
fd may be passed between processes and lead to misuse,

We have designed an fd cross-process automatic detection tool,
fdcheck_protect returns the fd containing the pid information,
indicating that the ownership of the current fd belongs to the pid and is not allowed to be used by other processes.
fdcheck_restore will obtain the true fd and check if the ownership of the fd is legal

For ease of understanding, let's give an example where
the following information is represented in 32-bit binary format

fd        00000000 00000000 00000000 10001010
pid       00000000 00000000 00000011 01010101

441b51b706 libc/regex: provide a separate kconfig for regex
in the initial impl, the regex is depends on ALLOW_MIT_COMPONENTS, and
if other modules want to use regex, also needs to depends on
ALLOW_MIT_COMPONENTS, which is ambiguity, so we provide a seperate
kconfig option for regex: LIBC_REGEX, which is depends on
ALLOW_MIT_COMPONENTS, but is enabled by default. Thus if
ALLOW_MIT_COMPONENTS is enabled, then the LIBC_REGEX is also enabled
either automatically, and this is more clear than controlled by
ALLOW_MIT_COMPONENTS option only.
