Note that this is a backwards incompatible change: Unlike POSIX, exit()
will not flush all open streams, so you are responsible for flushing or
closing all your streams before successful exit.
Also, file.c will now also require calloc.c (and malloc.c).
Updated the test cases accordingly.
Only implemented and tested for x86.
The close syscall was missing an indirection and therefore closed random
file descriptors (very visible in strace output).
Test 0104 did not properly null terminate the envp, resulting in -EFAULT
on execve syscall in case the next value in memory does not happen to be
0 (which it seems to be right now).
Paraphrasing OriansJ's IRC message while working on kaem:
GCC needs fflush(stdout) to get matching behavior, as M2-Planet doesn't
buffer. I guess we will need to make a fflush function (it'll do nothing
but return 0).
