Simon Cozens 7c0bc0bb92 Serialize invalid buffer to !! (text) or [] (json)
There is no generic deserialize - you have to choose glyphs or unicode - so there is no way to deserialize this buffer.

[ENOMEM] Return gracefully if stages isn't initialized correctly (#2639)
This happens if calls to 'm.lookups[table_index].push ()' has been
silently failed due to lack of memory.

This change just returns gracefully instead issuing the assert.

Ebrahim Byagowi 122a2897e4 [aat] Remove lcar support
Very low use, only two distinct font files, Apple Chancery.ttf and Hoefler Text.ttc
have it so it really doesn't worth the size addition and so, but one may argue that
whole ligature caret is low use but guess we better to encourage GDEF one anyway.

Christoph Reiter 03bd6ead44 [meson] Only pass required dependencies to everything
Instead of passing dependencies as required we used one giant shared
dependency list containing all dependencies for every library/executable.
While this kinda works, the specified deps are also used for generating
the pkg-config files and this leads to lots of Requires.private and Libs.private
entries which aren't really needed.

This removes the "deps" array and replaces it with a few smaller ones and
makes sure the public libraries only get passed the dependencies actually
needed.

Fixes #2441

Ebrahim Byagowi de0ec5f4fe [style] give ptem value when asked for opsz
ptem, used for AAT's tracking/`trak` table is equivalent to opsz of variable fonts.

For variable AAT fonts, such as SFNS, ideally variable axis of the hb_font_t
should be set and equivalent to ptem, https://crbug.com/1005969#c37

Ebrahim Byagowi c68ab4b52b Fix _get_ligature_caret's oob read issue
AAT::Lookup has no other way to detect whether it is returned from
a real and sanitized font data or from a null pool, this checks if
the table has been recognized valid by sanitizer by checking
table's major version which is zero if returned from a null pool and
non-zero if is from a sanitized font data, it is expected the other
calls of the table (unlikely to have more calls however) also do a
similar version check before calling the lookups used on the table.
