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.

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.
