devel/delta: fetch from GitHub

Make port more compliant with style, fetch from GitHub instead of a
local copy, respect port system CFLAGS, support installation of README
files depending on DOCS, support testing of the compiled port, take
maintainership from ports@.

The installed programs are identical to those of the previous port
version, except for CFLAGS from the ports system that are no longer
ignored.

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.

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.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

Fix CONFLICTS entries of multiple ports

There have been lots of missing CONFLICTS_INSTALL entries, either
because conflicting ports were added without updating existing ports,
due to name changes of generated packages, due to mis-understanding
the format and semantics of the conflicts entries, or just due to
typoes in package names.

This patch is the result of a comparison of all files contained in
the official packages with each other. This comparison was based on
packages built with default options and may therefore have missed
further conflicts with optionally installed files.

Where possible, version numbers in conflicts entries have been
generalized, some times taking advantage of the fact that a port
cannot conflict with itself (due to logic in bsd.port.mk that
supresses the pattern match result in that case).

A few ports that set the conflicts variables depending on complex
conditions (e.g. port options), have been left unmodified, despite
probably containing outdated package names.

These changes should only affect the installation of locally built
ports, not the package building with poudriere. They should give an
early indication of the install conflict in cases where currently
the pkg command aborts an installation when it detects that an
existing file would be overwritten,

One more small cleanup, forgotten yesterday. Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

- Add missing run dependency on perl - Shebangfix

Hand back my ports to the pool.

Ports require time and TLC which I no longer have.

devel/delta, devel/newfile: fix LICENSE

newfile is under the BSD3CLAUSE license
delta is under the BSD2CLAUSE license.

Simplify delta port by not using a for loop

- Convert to staging

Add NO_STAGE all over the place in preparation for the staging support (cat: devel part 1)

Add patch to respect CC

Remove now excess verbiage.

Convert some of my ports from USE_GMAKE to USES=gmake. The remainder have other pending patches which I must finish before conversion.

A portlint run over my ports revealed some false positives and these two minor formatting issues.  Fix them.

Clean up my ports (and a couple of ports@ owned ones):

- Fix COMMENT
- Add MAKE_JOBS_SAFE where appropriate
- Change ordering of LICENSE lines
- Fix new header format
- Etc.

Delta assists you in minimizing "interesting" files subject to a test of their interestingness. A common such situation is when attempting to isolate a small failure-inducing substring of a large input that causes your program to exhibit a bug.
