sysctl: make sys/sysctl.h self contained
sys/sysctl.h only needs u_int and size_t from sys/types.h. When the
sysctl interface was designed, having one more more prerequisites
(especially sys/types.h) was the norm. Times have changed, and to make
things more portable, make sys/types.h optional. We do this by including
sys/_types.h, defining size_t if needed, and changing u_int to 'unsigned
int' in a prototype for userland builds. For kernel builds, sys/types.h
is still required.
