David Corbett 645f4e7cdd Unhide CGJ before ccc=0 characters

Garret Rieger 9825e3dd2e [ENOMEM] fix access to unitialized memory. 
If the serialize() call fails to write the object then we can't safely read varstore_prime fields. Fixes https://oss-fuzz.com/testcase-detail/5137462782066688.

Tom Schoonjans eea9b59fc5 [meson] fix generating introspection 
Only libharfbuzz_gobject is introspectable, not libharfbuzz. Therefore,
