Bananymous e8a73f9696 BuildSystem: use -a with rsync

Bananymous 1a0d114861 LibC: Don't undef needed values in inttypes.h 2023-08-24 15:48:14 +03:00
Bananymous b05cf9ef09 BuildSystem: Base sysroot is now distributed as a tar ball
This allows file and directory permissions work as intended.

cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Bananymous b10168eb1c LibC: make printf buffer only 128 bytes
Only reason for it to be big is if you want super large zero padding
for your number. This will eventually be handled without the buffer.

Bananymous 8ec6d4c9fc LibC: we don't parse syscall arguments in unistd
We just call Kernel::syscall() with 5 arguments from the variadic function.

This was a necessary addition since the syscall() function
used over 2 KiB of stack space.

Bananymous adb14ba373 Kernel: Userspace signal handlers are now called one at a time
I added a syscall for telling the kernel when signal execution has
finished. We should send a random hash or id to the signal trampoline
that we would include in the syscall, so validity of signal exit can
be confirmed.
