Utilize the stronger guarantees on the call arguments from the

multiple of the word size.  This allows to remove the excessive memory
accesses to temporary buffer when saving the entropy word.

Streamline the assembly and unify it between i386 and amd64.

Fix resource free.

The order of releasing resources in mlxen was wrong, which caused
panic on reload of the module.

conf_ctx list should be released before stat_ctx list, otherwise
the leafs in conf_ctx list won't be released because of the dependancy.

The fix is to change the order of the releases.

Upgrade to the latest version of mtree from NetBSD.  This revision
re-removes the printing of size for non-regular files, supports
type-less root (.) entries as seen in a couple ports, and corrects a bug
in -N that caused expanded Subversion $FreeBSD$ strings in comments to
be processed as /etc/group entries.

Includes one trivial portability fix (including <stdint.h> in three
files) that has been submitted upstream but not yet committed.
