Subject: Fix include/errno.h to not use kernel header, and instead use
 bits/errno.h. This required we use _LIBC instead of __LIBC__ to be consistent
 with glibc. This had some sideffects in sys/syscalls.h.  While fixing things,
 I made everything use __set_errno() for (eventual) thread support.  -Erik
