Upgrade diffutils. 2/2

- update README.{DELETED,DRAGONFLY}
- regenerate header files
- adapt Makefile to vendor update

diff utils: Update from version 3.2 to 3.3

** New features
--new-file (-N) and --unidirectional-new-file now allow comparisons to
"-". A standard input that's closed acts like a nonexistent file.

A file name containing spaces, double quotes, backslashes or control
characters is now encoded in a diff header as a double-quoted C string
literal. The escape sequences \\, \", \a, \b, \f, \n, \r, \t, \v and
\ooo (a three-digit octal number between 0 and 255) are used.

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

diffutils: Upgrade to version 3.2

The majority of the changes were inherited from gnulib. There were only
a few observable differences from version 3.0:

Release 3.2 (2011-09-02) [stable]
Release 3

diffutils: Upgrade to version 3.2

Release 3.2 (2011-09-02) [stable]
Release 3.1 (2011-08-10) [stable]

Bug fixes
===================
diff no longer reports spurious differences merely because two entries
in the same directory have names that compare equal in the current
locale, or compare equal because --ignore-file-name-case was given.

Changes in behavior
===================
--ignore-file-name-case now applies at the top level too.
For example, "diff dir inIt" might compare "dir/Init" to "inIt".

New features
===================
diff and sdiff have a new option --ignore-trailing-space (-Z).

This is a complete overhaul in the diffutils makefile system. The
directories gnu/usr.bin/diff3 and gnu/usr.bin/sdiff have been removed
as a result. Those directories also used the deprecated patch

This is a complete overhaul in the diffutils makefile system. The
directories gnu/usr.bin/diff3 and gnu/usr.bin/sdiff have been removed
as a result. Those directories also used the deprecated patch approach.

Like grep before it, diffutils uses its own regex library. The
previous version used gnuregex.

The README.DELETED was woefully out of date. It is hoped this overhaul
will make future diffutils upgrades easier.

=========================================================
Noteworthy changes in release 2.9 (2010-02-11) [stable]
=========================================================

** New features

New diff option --suppress-blank-empty.

Bring back support for `diff -NUM', where NUM is a number,
even when conforming to POSIX 1003.1-2001. This change reverts to
the behavior of GNU diff 2.7 and earlier. This is a change only
when conforming to POSIX 1003.1-2001; there is no effect when
conforming to older POSIX versions.

This change is in response to decisions taken in the January 2005
Austin Group standardization meeting. For more details, please see
"Utility Syntax Guidelines" in the Minutes of the January 2005
Meeting <http://www.opengroup.org/austin/docs/austin_239.html>.

sdiff now understands '1' and '2' as synonyms for 'l' and 'r'.

** Changes in behavior

sdiff and diff3 now invoke diff, not $(bindir)/diff

** Administrivia

Noteworthy changes in release 3.0 (2010-05-03) [stable]
=========================================================

** Bug fixes

diff once again prints the required "\ No newline at end of file" line
when at least one input lacks a newline-at-EOF and the final hunk plus
context-length aligns exactly with the end of the newline-lacking file.
[bug introduced between 2.8.7 and 2.9]

** Changes in behavior

In context-style diffs, diff prints a portion of a preceding "function"
line for each hunk, with --show-function-line=RE (-F) or
--show-c-function (-p). Now, it trims leading blanks from such lines
before extracting a prefix. This is useful especially when a function
line is so far indented that the name itself would be truncated or not
included in the limited-width substring that diff appends.

diff once again reports a difference with the diagnostic
"Binary files A and B differ" when at least one of the files
appears to be binary. From 2.8.4 through diffutils-2.9, it printed
"Files A and B differ".
