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.

Switch from .CURDIR to the simpler, more legible SRCTOP.

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.
