cc1adf8d64 [hvf] Correctly initialize driver if no HVF library is available. 
Since this font driver is by default enabled in `modules.cfg` and its
availability controlled by `FT_CONFIG_OPTION_HVF`, we need to provide some
stubs so that HVF fonts can be correctly rejected if there is no HVF library
available.

Fixes issue #1409.

* src/hvf/hvfdrv.c (hvf_driver_class): Provide `hvf_face_init` and
  `hvf_slot_load_glyph` unconditionally.

* src/hvf/hvfload.c, src/hvf/hvfload.h (hvf_slot_load_glyph)
  [!FT_CONFIG_OPTION_HVF]: Define stub.
* src/hvf/hvfobjs.c, src/hvf/hvfobjs.h (hvf_face_init)
  [!FT_CONFIG_OPTION_HVF]: Define stub.

0c9b8e9e93 Support Hierarchical Variable Fonts (HVF) using Apple's 'libhvf' library.
