8ef4257dc8 [sanitize] change max ops to track number of bytes processed. 
Counting bytes as the operations is likely to be a better proxy for how
much work processing the table will cost vs. the current approach of
counting the number of sub-objects.

This should allow checks for max features, max scripts, etc. to be removed.

I tested this change against the full collection of fonts at https://github.com/google/fonts
and a max ops factor of 3 was sufficient to successfully sanitize all of them.

70110f6aaa Modify OffsetTo<>::sanitize() overflow check 
The code in question was introduced in 70eb2ff682.
Rewrite it to not call sanitizer check_range() as we want to use
check_range() for byte accounting.

cab9d5a57d hb-config: Include config-override earlier 
Currently config-override.h is included at the end of this file. This caused a problem for me while undefing HB_DISABLE_DEPRECATED, namely HB_IF_NOT_DEPRECATED was defined before actual undef took place and broke the whole build. I believe it would break builds for some other defines, too. Moving config-override.h include right after predefined configs is more sane and fixes all potential problems with includes.

b5e4032392 -Wno-unused-result 
GCC doesn't let one turn off the warning using "(void) foo()".
People have introduced macros that do "unused << foo()" instead.
Until we do something similar, silence gcc.

Clang on the other hand understands "(void) foo()".

743baf3543 [build] Don’t look for FontConfig 
We don’t currently use it anywhere. It was used briefly for the
hb-fc-list tool, but this tool have not been built since 2015:

    Until I figure out what to do about the API, and finalize
    the tool.

29708e959a [aat] Fix offsetToIndex math for out-of-bounds values 
Previously, some bad font data was accidentally being interpretted as
legit if it happened to not fall out of memory bounds. The intention
of the code was what this commit does.  I'm surprised we weren't getting
a "arithmetic between signed and unsigned values" warning / error
before.
