Bug 485621 – Get rid of freetype memory allocator in harfbuzz
* pango/opentype/*: Remove all occurences of FT_Memory. Use
malloc/realloc/free directly.
* pango/pango-ot*: Update to above.

Bug 485559 – Boston Summit HarfBuzz optimizations
* pango/opentype/*: HarfBuzz hacking to:
- Rename last remaining FT_Err stuff to HB_Err.
- Fix a couple invalid table paths to be permissive so
fonts work better. Particularly GDEF table for Nafees
Nastaliq is loaded and works great now.
- Optimize harfbuzz buffer to not copy/swap for simple
one-to-one and "copy" GSUB operations.
* pango/pango-ot*: Update to FT_Err to HB_Err renaming.
