908814a575 libc/lib_bzero:Add bzero prototype.
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

b87804c2ba libc/string: replace __builtin_ffsl with inline 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.

So if CONFIG_DISABLE_PTHREAD is not defined, but

0967eb4c24 avr32dev1: Fix compilation and nsh boot-up
I recently imported NuttX version 6.0 (and nsh) into a Microchip
Studio project [1] on Windows to figure out what was going wrong with
the avr32dev1 build. I also briefly checked NuttX version 10.

I worked with the assumption that the avr32 (avr32dev1) specific
changes to the codebase were minimal across NuttX releases.

For the initial proof of concept I used Microchip Studio version 7.0
(with the recent Microchip's ASF updates). I use avr32-gcc (4.4.7)
hosted here [2] for building NuttX for avr32dev1 on GNU/Linux.

Even with the Microchip Studio project, I had initial debug problems
with just stepping through the code a line at a time. I had to bring
in crt0, a trampoline stub and the linker file from one of my older
projects to really build on the suspicion I had with the linker file.

Perhaps an older version of avr32-gcc did something differently. I am
not sure about this. I used avr32-objdump to see the output sections
of the generated elf file. I just had to tweak the linker script to
ensure correct linking of the sections.

With those changes, I was able to inspect the UART sections within
NuttX Microchip Studio project.

Second important change: the transmit pin: I had to reassign the pin
to see the nsh console.

These are the currently assigned UART pins:

RX: PA_24 -> Physical IC pin 59
TX: PB_02 -> Physical IC pin 24

For the avr32dev1 board, they are pins: J1 (berg pin 28) and J2 (berg
pin 10).

In addition, the PR fixes silly compilation problems with avr32dev1.

I have tested the nsh build with my avr32dev1 boards. I used Atmel ICE
to program one of them (flash at 0x80000000) and dfu-programmer to
test my other board (flash at 0x80002000). The other RS-232 parameters
are the same as they were.

97096bed83 libs: fix the problem that the address obtained in thumb mode cannot be executed.
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.

90d73153fb riscv/arch_elf: Check for _HI20 relocation validity
As pointed out in #11322 there is a hardware design issue in RISC-V that
affects RV64 relocations. The problem is with how address bits are loaded
into registers via lui / auipc and sign extension.

If the hi20 relocation value happens to have its 32-bit sign bit set, i.e.
value is 0x80000000 (but not negative! i.e. negative in 64-bit format) the
relocation will fail, as the address is erroneously sign extended:

0x00000000_80000000 becomes 0xffffffff_80000000 which is not correct.

Also, make sure the correct opcode is used with PCREL_HI20, it expects
AUIPC (not LUI). The C compiler will never emit such code but when hand-
writing assembly code this can happen.

996625ec58 riscv/arch_elf.c: Handle PCREL_HI20/LO12_I/S relocations correctly
There is a problem with the current elf loader for risc-v: when a pair of
PCREL_HI20 / LO12 relocations are encountered, it is assumed that these
will follow each other immediately, as follows:

label:
	auipc      a0, %pcrel_hi(symbol)    // R_RISCV_PCREL_HI20
	load/store a0, %pcrel_lo(label)(a0) // R_RISCV_PCREL_LO12_I/S

With this assumption, the hi/lo relocations are both done when a hi20
relocation entry is encountered, first to the current instruction (addr)
and to the next instruction (addr + 4).

However, this assumption is wrong. There is nothing in the elf relocation
specification[1] that mandates this. Thus, the hi/lo relocation always
needs to first fixup the hi-part, and when the lo-part is encountered, it
needs to find the corresponding hi relocation entry, via the given "label".
This necessitates (re-)visiting the relocation entries for the current
section as well as looking for "label" in the symbol table.

The NuttX elf loader does not allow such operations to be done in the
machine specific part, so this patch fixes the relocation issue by
introducing an architecture specific cache for the hi20 relocation and
symbol table entries. When a lo12 relocation is encountered, the cache
can be consulted to find the hi20 part.
