02cdf743c2 Add prefer_decomposed() complex-shaper callback 
This allows the Indic shaper to request decomposed characters.  This will
handle split matra for free.  Other shapers prefer precomposed
characters.

aa7264123a Only form clusters if we are reversing 
This produces more accurate cluster mappings.  Cluster mappings are
minimal now.  Combining marks get their own cluster value most of
the time.

54d1a0d2b2 Form clusters before ensuring native direciton 
This is essential as ensure_native_direction uses cluster info that
is set by form_clusters().

5157e12a55 Rename HB_UNICODE_GENERAL_CATEGORY_COMBINING_MARK to HB_UNICODE_GENERAL_CATEGORY_SPACING_MARK 
Spacing_Mark is the current Unicode long-name for this property value.
The previous name was wrongly carried from glib.

f6fd3780e1 Let shapers decide when to apply ccmp and locl 
Instead of always applying those two features before the complex shaper,
let the complex shaper decide whether they should be applied first.

Also add stub for Indic's final_reordering().

c4641723fb [API] Add compose() and decompose() unicode funcs, rename other ones 
Add compose() and decompose() unicode funcs.  These implement
pair-wise canonical composition/decomposition.

The glib/icu implementations are lacking for now.  We are adding
API for this to glib, but I cannot find any useful API in ICU.
May end of implementing these in-house.

Changed all unicode_funcs callback names to remove the "_get" part.
Eg, hb_unicode_get_script_func_t is now hb_unicode_script_func_t,
and hb_unicode_get_script() is hb_unicode_script() now.

b70c96dbe4 Enable applying GSUB/GPOS features in multiple segments 
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=644184
among others.

Shapers now can request segmented feature application by calling
add_gsub_pause() or add_gpos_pause().  They can also provide a
callback to be called at the pause.  Currently the Arabic shaper
uses pauses to enforce certain feature application.  The Indic
shaper can use the same facility to pause and do reordering in the
callback.
