Kernel/LibC: remove PATH resoltion from kernel
...
I have no idea why I had made PATH environment variable parsing
to be part of the kernel. Now the shell does the parsing and
environment syscall is no longer needed.

Shell: Clean exit on ^D and use getchar()
...
Use getchar() instead of fread(&ch, 1, sizeof(char), stdin). This
is much cleaner.

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

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.
