libc: Add program_invocation_name
...
This is a GNU extension, but I'm fine with adding it to libc.
It's guarded by the _GNU_SOURCE feature test macro anyways.

Kernel, libc, userspace: Implement command-line arguments (argv)
...
The only thing missing now is for sh to pass them on.

Replace the rand() which reads from /dev/random with a Mersenne PRNG.
...
Much better now.
Also, it is seeded by reading from /dev/random at startup. Not sure if that's the best idea, but we'll see.

Make libc exit with a specific code if program initialization fails
...
Now you know, if a program exits with code -127 it's libc's fault :)

libc: Implement atexit() and _exit()
...
exit() now calls registered handlers before calling _exit().
And initialize_libc() can now register a handler to close stdout and stderr on program termination!! :)

libc: make stdout and stderr functional
...
what were before one extern FILE* without reference now are opened by libc on program initialization, to point to /dev/console by default.
