Subject: [PATCH] Add test suite for shaping results

The new test suite runs tests included under
hb/test/shaping/tests/*.tests, which themselves reference
font files stored by sha1sum under hb/test/shaping/fonts/sha1sum.
The fonts are produced using a subsetter to only include glyphs
needed to run the test.

Four initial tests are added for (Chain)Context matching,
of which three currently fail.
