Behdad Esfahbod bdfed8f113 [blob] Add failing versions of create API 
Fixes https://github.com/harfbuzz/harfbuzz/issues/2567

New API:
+hb_blob_create_or_fail()
+hb_blob_create_from_file_or_fail()

Use these in util/ to distinguish empty file from not-found file.
Only err on the latter.

Kurt Kartaltepe 2000f47ae5 [set] Compute is_subset by comparing pages.

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
