Tim-Philipp Müller a3892be701 [meson] fix spurious warning when building test/api C sources 
Fixes compiler warning

  test-unicode.c:589:1: warning: ‘test_unicode_properties_lenient’ defined but not used

which didn't happen with autotools.

Reason it does with meson is that the setup for C was slightly wrong.
We would only add -DHAVE_CONFIG_H to cpp_args which is only valid when
compiling C++ code, but not plain C code, and many of these tests were
plain C.

Instead pass -DHAVE_CONFIG_H via add_project_arguments() and make sure
to set both c_args and cpp_args when building test executables.

Ebrahim Byagowi 0d729b4b72 [avar] Fix out-of-bound read when input is bigger than all the coords 
'i' shouldn't become equal to array's length which as the increament
is happened at end of the loop, if the input is bigger than all the
table coords, it will be equal to array's length.

collect_unicodes() with clamp, calling add_range() 
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.

Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.

[glyf] Don't accept gids higher than maxp's glyphs number 
This specially becomes concerning on sub-components where a gvar table
that is sanitized using maxp's glyphs number overflows when a high gid
accepted here goes to it, maybe an additional check can be put there
also, this however feels to be enough.
