Nico Weber a38754d9f2 Kernel+LibC: Implement seteuid() and friends! 
Add seteuid()/setegid() under _POSIX_SAVED_IDS semantics,
which also requires adding suid and sgid to Process, and
changing setuid()/setgid() to honor these semantics.

The exact semantics aren't specified by POSIX and differ
between different Unix implementations. This patch makes
serenity follow FreeBSD. The 2002 USENIX paper
"Setuid Demystified" explains the differences well.

In addition to seteuid() and setegid() this also adds
setreuid()/setregid() and setresuid()/setresgid(), and
the accessors getresuid()/getresgid().

Also reorder uid/euid functions so that they are the
same order everywhere (namely, the order that
geteuid()/getuid() already have).
