Fix OSX alembic lookup

Merge branch 'master' into alembic_basic_io

- Remove references to Samplerate

- hdf5_hl requirement removed in Alembic 1.6.0

Patch by @ejnersan.

Remove extra statement from some test.

Merge branch 'master' into alembic_basic_io

Curves: read/write orders, knots, weights and radiuses.

Import: report a message in the UI in case opening a file fails.

Cleanup.

Fix crash dereferencing NULL ptr.

Update Alembic library to version 1.6, remove support for HDF5.

ALthough the FindHDF5 cmake module is still present for people to use,
HDF5 is removed from install_deps.sh. From now on, Alembic built with
HDF5 support is considered legacy and not "officially" supported.

NURBS: pad start and end of knots arrays with dummy knots to accomodate
for other software.

NURBS: fix out-of-bounds access of point weight, set default values for
point properties.

Drivers added to a cachefile are now evaluated during scene update.

Modify the way time offset and scaling works.

Now rather than having two separate properties to override or offset the
current frame or time to lookup inside an archive, a single property is
used to simply override the current scene frame.

Fix compile errors.

Merge branch 'master' into alembic_basic_io

Cleanup: curves.

NURBS:

- fix order in which points are written.
- check for the validity of all NURBS schemas.
- add properties for cyclic flags.
