Kernel/userspace: rework floating point math
...
SSE is now unconditionally enabled any where and most of math.h is now
actually implemented. using __builtin_<func> lead to many hangs where
the builtin function would just call itself.

Kernel/LibC: Add initial pseudo terminal support
...
This patch implements posix_openpt() and ptsname()
grantpt() and unlockpt() are left in LibC as stubs, as posix_openpt
currently does all of the needed work.

Kernel/LibC: Implement realpath
...
realpath is implemented as a syscall. This is not really required but it
was the easiest way to get it working as there is already path
canonicalization at kernel level.
