Kernel+LibC: Enforce a limit on the number of supplementary group IDs This patch adds the NGROUPS_MAX constant and enforces it in sys$setgroups() to ensure that no process has more than 32 supplementary group IDs. The number doesn't mean anything in particular, just had to pick a number. Perhaps one day we'll have a reason to change it.

Kernel+LibC+LibELF: Set stack size based on PT_GNU_STACK during execve Some programs explicitly ask for a different initial stack size than what the OS provides. This is implemented in ELF by having a PT_GNU_STACK header which has its p_memsz set to the amount that the program requires. This commit implements this policy by reading the p_memsz of the header and setting the main thread stack size to that. ELF::Image::validate_program_headers ensures that the size attribute is a reasonable value.

Kernel+LibC: Move name length constants to Kernel/API from limits.h Reduce inclusion of limits.h as much as possible at the same time. This does mean that kmalloc.h is now including Kernel/API/POSIX/limits.h instead of LibC/limits.h, but the scope could be limited a lot more. Basically every file in the kernel includes kmalloc.h, and needs the limits.h include for PAGE_SIZE.

Kernel+Libraries: Don't include limits.h from LibELF/Validation.h The fallout of this is that Kernel/Syscalls/execve.cpp doesn't have access to ARG_MAX anymore, so move that definition to Kernel/API as well
