Behdad Esfahbod 33ccc77902 [API] Make set_user_data() functions take a replace parameter
We need this to set data on objects safely without worrying that some
other thread unsets it by setting it at the same time.

Behdad Esfahbod 944b2ba1ce [buffer] Make API take signed int length
Since we already switched to accepting -1 as 'zero-terminated'.

Behdad Esfahbod 144cd49a0e [buffer] Accept -1 for text_length and item_length
A -1 text_length means: zero-terminated string.
A -1 item_length means: to the end of string.

Behdad Esfahbod 02aeca985b [API] Changes to main shape API
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.

Behdad Esfahbod 3935af1c0d [buffer] Remove wrong optimization
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.

Behdad Esfahbod af02933739 [API] Remove hb_*_get_reference_count()
This was a bizzare piece of API that I inherited from cairo.  It has
been wrong adding them to cairo in the first place.  Remove them before
someone uses them!

Behdad Esfahbod c0af193c8e Change buffer default properties to invalid
This includes HB_DIRECTION_INVALID and HB_SCRIPT_INVALID.

The INVALID will cause a "guess whatever from the text" in hb_shape().
While it's not ideal, it works better than the previous defaults at
least (HB_DIRECTION_LTR and HB_SCRIPT_COMMON).
