[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.

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.
