Add a common header file, xcrypt.h, for the various extended crypt
routines (md5, sha256, sha512).

Move <syslinux.h> to <syslinux/idle.h> since that was all that was there;
do_idle() in libutil can simply be a macro for syslinux_idle() or
sched_yield() as appropriate.

Library support for constructing initramfs.  This version is *not*
complete, as it doesn't take into account alignment requirements
properly.
