Log message:
Revbump for ocaml 4.02.0.
(Some packages omitted because they will be updated to new versions)

Log message:
Screams for pkg-config.

Log message:
Don't redefine MAP_ANONYMOUS is already defined. Fixes build on netbsd-7

Log message:
Bump for perl-5.20.0.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Log message:
Make it build on netbsd-6 (and maybe netbsd-5):
Don't include other libraries in an archive, our ar seems to not
support it. Instead, list all libraries at link time.

Log message:
Mark packages that are not ready for python-3.3 also not ready for 3.4,
until proven otherwise.

Log message:
Remove example rc.d scripts from PLISTs.

These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.

Log message:
add patch from upstream to fix use-after-free under memory pressure
(CVE-2014-1950)
bump PKGREV

Log message:
No need to have two variables for the same logic.
Replace PYTHON_PATCH_SCRIPTS with REPLACE_PYTHON.

Log message:
Mark packages as not ready for python-3.x where applicable;
either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE=  33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE=  33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.

Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.

Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.

Whitespace cleanups and other nits corrected, where necessary.
