MFC r315170:
r315170 (by imp):

Adopt SRCTOP in usr.bin

Prefer ${SRCTOP}/foo over ${.CURDIR}/../../foo and ${SRCTOP}/usr.bin/foo
over ${.CURDIR}/../foo for paths in Makefiles.

Silence on: arch@ (twice)

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.

Increase MAXTABLE to the maxmimum possible value. The default value is too
low for complex parsers. Note it was one of those memory optimization hacks
back in the day.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Update to byacc 20140409
Among all the modifications, this new byacc also solves a 14 year old bug [1]

Migrate most of tools/regression/usr.bin/ to the new tests layout.

I'm starting with the easy cases. The leftovers need to be looked at a
bit more closely.

Note that this change _does_ modify the code of the old tests. This is
required in order to allow the code to locate the data files in the
source directory instead of the current directory, because Kyua
automatically changes the latter to a temporary directory.

Also note that at least one test is known to be broken here. Actually,
the test is not really broken: it's marked as a TODO but unfortunately
Kyua's TAP parser currently does not understand that. Will have to be
fixed separately.

Add missing bits from the vendor's 2005-05-04 change to
contrib/byacc/makefile.in ("add YYPATCH here so it can be tested by
applications") so that applications have a hope of detecting newer
FreeBSD YACC output from an older one.

Setting WARNS=6 is useless, as it is already the default

Reported by: Sascha Wildner

Change warning level to 6

Import byacc from invisible island, it brings us lots of compatibilities with
bison, keeping full compatibility with our previous yacc implementation.

Also bring the ability to create reentrant parser

Inherit WARNS from parent directory.

Submitted by: marius

Change to ANSI-C function definitions.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Remove NO_WERRORs and WARNS=n's. To be revisited after GCC3.

WARNS=2 fix, but do not set this im Makefile, because this ill be the
default for src/usr.bin/

WARNS=2 and s/register//.

Set NO_WERROR=true because there are some flex(1) issues that need
to be dealt with.

beforeinstall -> SCRIPTS.

MAN[1-9] -> MAN.

$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Add RCS id's since these files have left the default branch.

Install yacc with a link as byacc (and the man page). Some gnu autoconf
scripts that check for features/fixes in bison also check for byacc and
dont find it unless there is a 'byacc' in the path.

Change `install' to `${INSTALL}' so that default install flags can be
specified in the top level Makefiles.
