Check for that coming next commit.

Behdad Esfahbod 7e8c389546 Minor warnings fixes

by design.  Fix a few easy ones.

Behdad Esfahbod 7627100f42 Mark unsigned integer literals with the u suffix
Simplifies hb_in_range() calls as the type can be inferred.
The rest is obsessiveness, I admit.

Behdad Esfahbod 6faff8e413 Add static storage classifier to inline functions

breaking anyone's build.

Behdad Esfahbod 07a52b6211 Give up sanitizing after 100 edit requests
Such fonts are *definitely* really broken.  Give up.
Limits time spent in sanitize for extremely / deliberately broken
fonts.  For example, two fonts with these md5sum / names:

  9343f0a1b8c84b8123e7d201cae62ffd.ttf
  eb8c978547f09d368fc204194fb34688.ttf

were spending over a second in sanitize!  Not anymore.
