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.

Log message:
Import libhid-0.2.16 as devel/libhid.

libhid is a rewrite of libHID[0] and aims to provide the same functionality
from a more organised framework. It aims to provide a layer of abstraction for
accessing HID-class devices over USB or serial lines (similar to what libusb
provides for the base USB protocol).
  http://www.ghz.cc/~clepple/libHID/doc/html/
libhid has been designed because it is needed in two other projects
(libphdigets and nut). As such, it does not have a complete featureset yet but
is rather a work in progress (alpha state). We invite everyone to contribute
or get in touch with us for additional features.
Please find more information on the project website:
