Log message:
Always extract the full Python distfile for modules.

This retires an old "optimisation" that over time has created more
problems than it solved, including various questions from users about
the ignored patch failures.

No manual corrections.

py-readline: update HOMEPAGE

Log message:
Follow some redirects.

Log message:
Set USE_GCC_RUNTIME=yes for packages which build shared libraries but do
not use libtool to do so.  This is required to correctly depend upon a
gcc runtime package (e.g. gcc47-libs) when using USE_PKGSRC_GCC_RUNTIME.

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.
