Set BUILDLINK_ABI_DEPENDS correctly (with +=, not ?=)
It turns out there were a lot of these.

Fix path to itself.

Update to Erlang/OTP R13B03.

SunOS, Java and ODBC support by Filip Hajny
and some tests by Matthias Kretschmer.


Changes in R13B03
-----------------

There are mostly error corrections, but also some new functionality.
Some highlights in the R13B03 release are:
 - Native Implemented Functions (NIFs) still experimental but very useful.
 - The documentation is built in a new way using xsltproc and Apache FOP.
   The layout is changed both in HTML and PDF versions. This is the first
   step, more changes and improvements will come in the following releases.


Changes between R13A and R13B02 are unknown.


Changes in R13A
---------------

1.1 Erlang Language and Run-time System

Multi-core and SMP performance improvements

There SMP performance is significantly improved:
 - multiple, scheduler specific run queues;
 - further optimized message passing;
 - CPU-bound scheduler threads.

Unicode support as described in EEP10

New BIF's: atom_to_binary/2, binary_to_atom/2, binary_to_existing_atom/2.

Independent Erlang clusters on the same host


1.2 New Applications

Reltool, release management tool.
WxErlang


1.3 New features in Existing Applications

Common_test
 - SSH and SFTP support
 - test case groups

Dialyzer
 - opaque type declarations;
 - UTF segments handling

SSL
 - pure Erlang implementation (except crypto routines)

STDLIB
 - scanner has been augmented to return white-space, comments
 and exact location of tokens.

Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Fixes pkglint warnings.

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

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.

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).

Recursive revision bump / recommended bump for gettext ABI change.

- Update Erlang to R10B-9.  (The changes are innumerable, this package hasn't
  been updated in more than two years.)
- Add a buildlink3.mk file.
- Make the Java dependency optional, and disable this option by default (this
  will make erlang build in more bulk builds).

Ok by wiz.

Back out my two previous commits -- they were committed on the wrong branch.
Sorry.

Fix a local reference in the buildlink3.mk file and reindent it.

file buildlink3.mk was initially added on branch pkgsrc-2005Q3.
