Remove Ex-MASTER_SITEs. From Zafer Aydogan.

Log message:
Prepare for switching to NO_MTREE=yes.

Log message:
When all source files are compiled with a Fortran compiler, why should a
C compiler be used for linking them?

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Log message:
Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.

Log message:
Over 1200 files touched but no revisions bumped :)

RECOMMENDED is removed. It becomes ABI_DEPENDS.

BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.

BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.

BUILDLINK_DEPENDS does not change.

IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".

Added to obsolete.mk checking for IGNORE_RECOMMENDED.

I did not manually go through and fix any aesthetic tab/spacing issues.

I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.

I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.

As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.

As discussed on tech-pkg.

I will commit to revbump, pkglint, pkg_install, createbuildlink separately.

Note that if you use wip, it will fail!  I will commit to pkgsrc-wip
later (within day).

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 digests in addition to SHA1 ones.

Log message:
Nuke USE_FORTRAN and bring the f2c handling within the mk/compiler
framework.  The list of changes include:

  * Modify compiler.mk so that "c" is always prepended to USE_LANGUAGES,
    so we no longer need to say it in package Makefiles.  Packages
    should now append to USE_LANGUAGES instead of setting it.

  * Create mk/compiler/f2c.mk which implements another pseudo-compiler
    "f2c" that may be used with any C compiler backend, e.g.

	PKGSRC_COMPILER= f2c ccache gcc

  * Teach the various "real" compiler files, e.g., sunpro.mk, mipspro.mk,
    etc., to use f2c if the native Fortran compiler isn't present.

Packages that use Fortran should now simply include the line:

	USE_LANGUAGES+=	fortran

in the package Makefile.
