Behdad Esfahbod a9a607d360 [variations] Support multiple axes with same tag, aka HOI
The axes in fvar are in arbitrary order, NOT sorted. Hence have to
lsearch all entries.

Ebrahim Byagowi 40166eb0e5 [var] Fix the just introduced hb_font_set_var_coords_design storing bug
The memcpy call was using the current coords count which is zero initially so no copy at all.

Sad that no test has caught it, should see why, will however with the upcoming style API tests.

Behdad Esfahbod 2682efb02d Revert "Deprecate font kern API"
This reverts commit d219f899f4.

API change: Un-deprecate font kern API.

Part of https://github.com/harfbuzz/harfbuzz/issues/1682

We should document that this API is only necessary to hook up
non-OpenType kerning.  hb-ot-font will continue to NOT implement them.

Behdad Esfahbod 4d31662b5d Don't install ot-font funcs on new fonts if HB_NO_OT_FONT defined
Currently linker cannot GC hb-ot-font completely because we install
it on fonts by default.  Don't do that if HB_NO_OT_FONT defined.

Behdad Esfahbod 8d05bf7dc0 Fix cast-align error
If compiler doesn't inline StructAtOffset, this was an error since we
only disable cast-align at call-site.  So, move the cast out.
