Behdad Esfahbod 2337f0d047 Internally use hb_malloc/.../hb_free instead of malloc/.../free
Redefining those stock names as macros was conflicting with gcc 10
headers.

Behdad Esfahbod e40c0d82e2 [ENOMEM] Handle immutable buffer in shape_full()
Move the content_type changing to shape_plan_execute() where it belongs.
Skip setting if content type is UNKNOWN, which happens with empty buffers
only, including the immutable buffer.

Alternate fix to https://github.com/harfbuzz/harfbuzz/pull/2606
and https://github.com/harfbuzz/harfbuzz/pull/2625

Ben Wagner b918cd8c76 Document hb_feature_t.
This documents hb_feature_t. This is motivated mostly by the ambiguity
of the units for 'start' and 'end' (clusters) and whether they are
inclusive or exclusive. This also documents that for lookup type 3 the
value is the one based index into the alternates and that in a list of
features later feature values override previous feature values with the
same tag.

We ignore the case of static libraries.
