MANPREFIX: eleminate its usage  and move man to share/man

Mk/**ruby.mk: Switch from USE_RUBY=yes to USES=ruby

Switch from Mk/bsd.ruby.mk to Mk/Uses/ruby.mk

Notable changes are.

- Mk/bsd.ruby.mk is moved to Mk/Uses/ruby.mk.
- USE_RUBY=yes is replaced with USES=ruby.
- USE_RUBY_EXTCONF is replaced with USES=ruby:extconf.
- USE_RUBY_RDOC is replaced with USES=ruby:rdoc.
- USE_RUBY_SETUP is replaces with USES=ruby:setup.
- RUBY_NO_BUILD_DEPENDS and RUBY_NO_RUN_DEPENDS are replaced with
  USES=ruby:{build,none,run}.
- RUBY_REQUIRE isn't used anywhere, so removed.
- USES=gem now implies USES=ruby.

This is mainly the work of yasu@ at https://reviews.freebsd.org/D27863

I have just made some cosmetic changes and ran exp-run to test that the
tree is not in a BROKEN state.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

misc: remove 'Created by' lines

Remove # $FreeBSD$ from Makefiles.

Return knu@'s ports to the pool after his commit bit was safekept.

misc/inplace: convert to USES=shebangfix

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Remove Author from pkg-descr and white space fixes

Allow staging as a regular user

Convert some more USE_BZIP2 to USES=tar:bzip2

Approved by:	portmgr (not really, but touches unstaged ports)

Remove indefinite articles and trailing periods from COMMENT, plus minor
COMMENT typos and surrounding whitespace fixes. A few Makefiles where not
included as they contain Latin-1 characters that break the Phabricator
workflow. Category M.

- Stage support

Add NO_STAGE all over the place in preparation for the staging support (cat:

Update to 1.2.3, which works with ruby 1.9 and later.

- Get Rid MD5 support

Update to 1.2.2. (released in 2008..)

Update to 1.2.2. (released in 2008..)

Update to 1.2.0.

- Suffix every temporary file with the same suffix as the original
  file, so that file name aware programs can play nicely with it.

Update to 1.1.0.

- Add -D/--debug and adjust the verbosity level.

- Show before and after file sizes when -v is specified.

- Introduce a configuration file in which command aliases can be
  defined.

- Add -i/--preserve-inode so inode numbers are preserved even when -b
  or -s is specified.

- Add SHA256

With portmgr hat on, reset maintainership of knu's ports since he has
been inactive more than 6 months.  We hope to see him back sometime.

Update to 1.0.4.

- Do not permit interruption with signals during a file replacement.

- Correct an informational message.

Update to 1.0.3.

Define RUBY_SHEBANG_FILES.
Pass MANPREFIX. (currently unused)

Add misc/inplace.

The inplace(1) command is a utility to edit files in-place through
given filter commands preserving the original file attributes.  Mode
and ownership (user and group) are preserved by default, and time
(access and modification) by choice.

Examples:
    # Sort files in-place using sort(1):
    inplace sort file1 file2 file3

    # Process image files preserving time and taking backup files:
    inplace -t -b.orig 'convert -rotate 270 -resize 50%% %1 %2' *.jpg
