r314659:

usr.sbin: normalize paths using SRCTOP-relative paths or :H when possible

This simplifies make logic/output

r314676:

Fix build after r314656

Some of the changes I introduced to use .ALLSRC were correct in spirit,
but incorrect in reality -- in particular, ../Makefile.inc hadn't been
pulled in via bsd.init.mk (via bsd.lib.mk, bsd.prog.mk), so the value
of .ALLSRC (evaluated immediately) was empty. .include bsd.init.mk
explicitly so we can be certain that the values used as dependencies in
the targets are defined when the target recipe has been evaluated.

Reminder: thou shalt separate out separate functional changes before
committing them.

MFC r307800, r307801

r307800:

Sources from the "current" build tree and generated sources in the
object tree should be used instead of sources and headers from the
already installed source tree on the build host.

This was noticed while addressing issues in the upcoming amd update.

r307801:

Align whitespace.

r307801 is related to r307800 however it was a separate commit to
HEAD in order to maintain a separation between the functional change
and a correction of style.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

We now have to use part of the vendor supplied xdr_func.c.
util renamed to strutil to be more clear of its purpose.

For variables that are only checked with defined(), don't provide
any fake value.

Mark all internal libraries with INTERNALLIB.

Use the native mount and nfs_prot headers.
Also generate nfs_prot_x.c in ANSI-C mode.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

$Id$ -> $FreeBSD$

Fully use our own generated files for NFSv3.

With the change to the 4.4Lite2 mount interface we don't need special
conf files.
