MFC r315776:

Rename tests from <foo> to <foo>_test to match the FreeBSD test suite
naming scheme

usr.bin/diff/diff_test was renamed to usr.bin/diff/netbsd_diff_test
to avoid collisions with the renamed FreeBSD test.

r289172:

Refactor the test/ Makefiles after recent changes to bsd.test.mk (r289158) and
netbsd-tests.test.mk (r289151)

- Eliminate explicit OBJTOP/SRCTOP setting
- Convert all ad hoc NetBSD test integration over to netbsd-tests.test.mk
- Remove unnecessary TESTSDIR setting
- Use SRCTOP where possible for clarity

Avoid shadowing a local scratch variable,

Expand *n't contractions.

Added the EXIT STATUS section where appropriate.

Add a standard DIAGNOSTICS section.

Add a cross-reference to colcrt(1).

Sort #include directives and remove one duplicate that crept in to the
previous commit.

Add support for multibyte characters, loosely based on Bruno Haible's
work in the util-linux package.

Document incorrect handling of multibyte characters.

Deal with double whitespace.

ANSIify function definitions.
Add some constness to avoid some warnings.
Remove use register keyword.

Remove local prototypes for main().

Sort options in Description section.

Note SUSv2 conformance.

Use `The .Nm utility'

remove __P

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Use __FBSDID().

Remove the misnamed `xmalloc' and replace its uses with the realloc (along
with error checking) that it actually was.

Remove whitespace at EOL.

Add the -p flag to force unknown control sequences to be passed
through unchanged.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
