- Update `graphics/alembic' to version 1.7.1 [*]
- Make HDF5 support (and thus the dependency) optional
- USE_GL and Boost dependencies are no longer needed, remove them and
  their associated patch files
- Remove CMAKE_ARGS: it was setting values which are the defaults now
- Add missing USE_LDCONFIG and move USE_GITHUB together with other USE_*
  knobs: while it makes sense to have a dedicated GitHub-related block
  of knobs, single USE_GITHUB does not really warrant it
- Remove HDF5_ROOT gimmick for Alembic < 1.6.0's AlembicHDF5.cmake as it
  is no longer required (ditto for the patch)

Allow HDF5 to be found with CMake >= 3.6.0.

CMake's FindHDF5.cmake underwent some refactoring upstream and it now respects
the HDF5_ROOT variable in more places and separates HDF5_LIBRARIES from
HDF5_HL_LIBRARIES.

Do some slight adjustments to the Alembic port for it to continue working with
the upcoming CMake 3.6.1 (they are no-ops with CMake 3.5.2 which is currently
in the ports tree):
- Set HDF5_ROOT via CMAKE_ARGS so that Alembic does not set it to a nonsensical
  value.
- Add HDF5_HL_LIBRARIES to ALEMBIC_HDF5_LIBS so that libhdf5_hl.so continues to
  be passed to the linker.
