libc: Change bits/macros.h to use a __lc_ prefix for internal macros
...
That way, we don't pollute user programs with our own 'noreturn' and 'deprecated' macros

libc: #define STDOUT_FILENO and STDERR_FILENO
...
Still missing stdin >.<

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: Add support for the new exec() system call
...
execv() is a temporary wrapper that ignores the second parameter, while execve() and execvp() still error out.

Kernel/syscalls: Modify sys_write to accept a file descriptor and write to it
...
Previously, sys_write only wrote to the tty. Now, it uses the VFS interface, as it should.

libc: Implement wrappers for sys_{open,read,write}
...
read() and close() are in unistd.h, but open() in fnctl.h.
I thought only the definitions for O_SOMETHING were in fnctl.h, but it is as it is.
Don't know why, but let's not anger the Unix gods.
The FILE* C API is pending as well.
