Using graphite2's comparerenderer suggests that this makes hb-ft 15
times faster.  No caching layer needed anymore.

hb_shape() now accepts a shaper_options and a shaper_list argument.
Both can be set to NULL to emulate previous API.  And in most situations
they are expected to be set to NULL.

hb_shape() also returns a boolean for now.  If shaper_list is NULL, the
return value can be ignored.

shaper_options is ignored for now, but otherwise it should be a
NULL-terminated list of strings.

shaper_list is a NULL-terminated list of strings.  Currently recognized
strings are "ot" for native OpenType Layout implementation, "uniscribe"
for the Uniscribe backend, and "fallback" for the non-complex backend
(that will be implemented shortly).  The fallback backend never fails.

The env var HB_SHAPER_LIST is also parsed and honored.  It's a
colon-separated list of shaper names.  The fallback shaper is invoked if
none of the env-listed shapers succeed.

New API hb_buffer_guess_properties() added.

Not complete yet, font selection doesn't work.  But hey it shapes!

This is not supposed to be a production backend, more like a testing
backend.

(and revert change have_icu change I mistakenly pushed out)

With these changes, on Ubuntu I can do:

./configure --host=i586-mingw32msvc  && make

There are no API guarantees just yet, but I *expect* that no
incompatible API changes to happen before 1.0.0.

Update NEWS.

The versioning is automatic.  For now, soname-major is 0.  With
the 1.0.0 release it will jump to 1 and stay there forever.

Apparently there exist systems with mprotect(), but not mmap()?

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

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.

With gcc on arm, request 8-bit structure alignment.

Currently doesn't handle script or direction.

We just require people to have libtool, pkg-config, etc installed
when running autogen.sh

It was unmaintained and the code has to be replaced to use the new
grphite-ng code base.

Patch from suzuki toshiya.

Graphite module not updated.
Bump version to 0.3.

Also remove wrong ASSERT_SIZE that would trigger only when not using
flexible arrays (which was the case on win32, but not with gcc).
