Corresponds to the problem of name resolution with different IP
address types in networks where only one of IPv4 or IPv6 can be
used due to physical layer reasons (e.g., LTE networks).
When we are using newlib as libm, we can consider newlib-esp32 for esp32
hardware. An it contains some optimization for esp32 hardware.
Besides, two small issues has been fixed.
1. add the tar ball to .gitignore
2. Fix the some build warnings
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.
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.

| 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.

If -fstack-protector-all is enabled, gcc linker will need GCC
SSP(Stack Smashing Protector) support, Since the implement of SSP
is related to the OS, most of embedded toolchain does not provide
ssp support, so an error will be reported when linking:
enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES
arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory
arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory
https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985
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
the implementation of lssp/lssp_nonshared will not be referenced

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.

For "%e" conversion, the exponent always contains at least two digits.
That means if the value is zero, the exponent is 00, not 0.
Such as code:
printf(buffer, sizeof(buffer), "%e", 1.232323232323);
printf(buffer, sizeof(buffer), "%e", 12.32323232323);
printf(buffer, sizeof(buffer), "%e", 123.2323232323);
Expected output:
1.232323e+00
1.232323e+01
1.232323e+02

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
