All good now.

Not used for anything right now.  Will use to get num_glyphs in the future.

get_contour_point now takes glyph id before point_index.

get_kerning now takes a vector to fill-in.

Not quite useful just yet.

Should have been done as part of da975419

The test/object test is passing again, instead of deadlocking.

Now the test/object test deadlocks as expected.  Fix coming.

Exposes the non-atomicity of user_data opertaions at this time because
we call finish() while still locked and modifying the object.  In fact,
I'm surprised that it doesn't deadlock.  It should.

It uses locale information to detect default language.  It's used by
hb_shape() whenever language is not set on the buffer.

Not sure how to properly test it in the test suite.  Tested by observing
that with DejaVu Sans we select the proper local glyph version for U+431
under Serbian locale.  See http://www.pango.org/ScriptGallery

Step version up to 0.5.0.

Also, fix to pass "make distcheck"

No one who builds harfbuzz static uses the autotools build system to do it.

Since we're not win32-dll clean the way libtool docs define it.

While the cluster fields of the glyph string are usually sorted, they
wouldn't be in special cases (for example for non-native direction).
Blindly using bsearch is plain wrong.  If we want to reintroduce this
optimization we have to make sure we know the buffer clusters are
monotonic and in which direction.  Not sure it's worth it though.

For now, by taking a global user_data mutex.
