The lowest bit of the thumb instruction is 1 by default, which is used to distinguish arm instructions and thumb instructions.
Fixed the problem of misalignment of symbol table when performing binary search
In arm, the lowest bit of the instruction is 1, which is a thumb instruction, and 0, which is an arm instruction.
The nm command was used in mkallsym.sh before, and the result it will return will set the lowest bit of the thumb instruction to 0. There will be a one-byte deviation during binary search, so mkallsyms.py will also set the lowest bit to 0 according to the previous format.
```sh
arm-none-eabi-nm -Cn nuttx | grep hello
0801c384 T hello_main
arm-none-eabi-objdump nuttx -t |grep hello
0801c384 g F .text 0000004c hello_main
arm-none-eabi-readelf nuttx -s |grep hello
4558: 0801c385 76 FUNC GLOBAL DEFAULT 1 hello_main
```
However, in the following case, when you need to find the function address according to the symbol name and execute the corresponding function, the lowest address obtained is 0. It will follow the arm instruction, causing an exception.
```c
void sym_test(void)
{
printf("call sym_test\n");
}
int main(int argc, FAR char *argv[])
{
FAR void *addr = sym_test;
printf("sym_test:%p %pS\n",addr, addr);
printf("sym_test - 1: %pS\n", (char *)addr - 1);
printf("sym_test + 1: %pS\n", (char *)addr + 1);
size_t size;
void (*func)(void);
const struct symtab_s *sym = allsyms_findbyname("sym_test", &size);
printf("sym_test:%p %pS\n",sym, sym);
func = sym->sym_value;
func();
return 0;
}
```
Therefore, you need to change mkallsyms.py back to the correct result and correct the binary search.

after the CI environment is upgraded to Ubuntu 22 and GNU make is upgraded to 4.3,
`warning: jobserver unavailable: using -j1. Add '+' to parent make rule.` warning appears.
this because when executing a shell in Make, the new shell created will not inherit the parallel environment of the parent shell(jobserver).
in our case:
```
$ make olddefconfig
this execute into Unix.mk twice,
because it will call make clean_context in its target
olddefconfig:
$(Q) $(MAKE) clean_context
```
We replace the shell call with the target of the Makefile

Fix an issue that math library header files are not exported by make export.
Create symbolic links of libmcs, newlib and openlibm header to nuttx/include.
Summary:
- Upgraded to xpack-riscv-none-elf-gcc-12.3.0-2 to resolve symbol recognition
issues in riscv-none-elf-gdb, as reported in
https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/issues/22.
Impact:
- Expected to enhance toolchain stability with no negative side effects.
Testing:
- Verified with rv-virt:netnsh and rv-virt:netnsh64 configurations

Add the Sim WiFi function, which can provide the wifi operating on nuttx sim emulator,
and support two modes that simulate wifi, HWSIM and RNC(real network card).
- In the HWSIM mode, we simulates two wlan interfaces. The wlan0 is STA and
the wlan1 is AP. The wlan0 can connect to the wlan1 in the nuttx simulator.
- In the RNC mode, we can use the same wlan interface name on the nuttx simulator
to control the connection behavior of the real wireless card.

NodeMixin have attrubute called size and it is set property.
Overwrite this property by _size but it will make report incompatible.
Create a new class NuttxDictExporter to renaming _size into size.
we can mount a zipfile in nuttx use mount command like this:
mount -t zipfs -o /data/test.zip /zip
The zipfs is a read only file system,The advantage is that it
does not occupy additional space when reading the decompressed file.
When used, reading and decompression operations are simultaneous.
The known disadvantage is that when using seek to read forward,
it will reopen and cause slow speed problems.
