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

We haven't been keeping this updated. So, while we don't expose the
symbols in the headers if HB_DISABLE_DEPRECATED is defined, we still
always build them.
Unused as of now. To be wired up to normalizer, which would remove
overhead and allow hb-ot-font initialization to become a no-op, so
we can enable it by default.
