Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Import a new version of NetBSD's mtree.

This version of mtree implements a new flag (-O) that can be used to
restrict the tool to certain pathnames. Also, it fixes a compiler
warning generated by -Wmissing-variable-declarations.

Acked by: brooks

Always install our mtree as /usr/sbin/fmtree and link it as
/usr/sbin/mtree by default.

Add a src.conf option WITH_NMTREE that causes NetBSD's mtree to be linked
as /usr/sbin/mtree as well as /usr/sbin/nmtree.

Add the missing '$' from the LIBNETBSD variable

Add NetBSD's mtree to the tree and install it as nmtree as the first step
towards replacing our mtree.
