This commit fixes erronous assignment of lib_pwd_globals.c
previously guarded by CONFIG_LIBC_PASSWD_FILE. Original
Make.defs file has this in CSRCS scope.

The ELF loader needs to load the app into the memory before
executing it from the same location. As expected, this memory space
should be able to execute code. For architectures containing data
and instruction buses, the instruction bus may not be able to be
accessed in a non-aligned way, which is usually required when
copying data to that location. Eventually, this same memory space
can be accessed through the data bus, using different address
ranges. This commit enables accessing the memory through the data
bus to copy the app's data before executing it when
`CONFIG_ARCH_HAVE_TEXT_HEAP_WORD_ALIGNED_READ` is enabled.
To solve some compilation issues encountered during the porting of
third-party libraries, this function has been added.

Add a common method to format backtrace to buffer, so it can be used by both mm, fs and other possoble modules.

Disable sincos optimization for all functions in this file,
otherwise gcc would generate infinite calls.
Refer to gcc bug 46926.
-fno-builtin-sin or -fno-builtin-cos can disable sincos optimization,
but these two options do not work inside optimize pragma in-file.
Thus we just enforce -O0 when compiling this file.

pointer comparison is unsigned, when returning -errno will be converted
to a large positive number, can not enter the error handling branch,
therefore, the error code is returned directly and the sem is returned
through the parameters.

Implement the bzero function as an alternative to macro expansion.
and support gcc FORTIFY_SOURCE features for nuttx libc
This function will use gcc's function
__builtin_dynamic_object_size and __builtin_object_size
Its function is to obtain the size of the object through compilation,
so as to judge whether there are out-of-bounds operations in commonly used functions.
It should be noted that the option -O2 and above is required to enable this function

In the gcc-riscv compiler, __builtin_ffs will call ffs, and calling __builtin_ffs in ffs will cause recursion
Change ffs to an inline function, and compile ffs implemented by nuttx by default.
Only call the implementation of nuttx when the compiler cannot provide an ffs implementation.

Because `set_source_files_properties` in cmake will overwrite the properties instead of appending them.
This module implements addition and deletion by
first `getting_source_file_property` and then `set_source_files_properties`

This commit adds support for reallocarray function. The functionality
is the same as for standard realloc, but the function also checks for
multiplication overflow and fails safely in case it occurs.

The current macro guard for TLS related symbols is
not enough, only if !defined(CONFIG_DISABLE_PTHREAD)
and CONFIG_TLS_NELEM > 0, the TLS related symbols
will enabled.
So if CONFIG_DISABLE_PTHREAD is not defined, but
TLS is disabled, the reference to TLS related symbols
will cause build error (undefined reference to xxx).
