Behdad Esfahbod f28b1c823d [arabic] Implement Windows-1256 private shaping 
Bug 1045139 - The Arabic text with "MS Sans Serif" font is rendered bad
https://bugzilla.mozilla.org/show_bug.cgi?id=1045139

This is only enabled on Windows platforms, and requires support from
Uniscribe to work.  But for clients that do hook up to Uniscribe, this
fixes shaping of Windows-1256-encoded bitmap fonts like "MS Sans Serif".

The code and table together have just less than a 1kb footprint when
enabled.

UNTESTED.  I might even have broken regular Arabic fallback shaping.

Behdad Esfahbod 9e834e29e0 [hebrew] Zero mark advance by GDEF late 
Seems to be what Uniscribe does.

At this point I think it's work checking our default...

Fixes Bug 76767 - Zeroing of advance of 2nd component of multiple
substitution with SBL Hebrew

Micro-test added.

Behdad Esfahbod 6f2d9ba52a Add old-Myanmar shaper 
Looks like Unsicribe responds to the 'mymr' tag by zeroing marks
GDEF_LATE instead of generic-shaper UNICODE_LATE.  Implement that.

We now handle U+FFFD replacement in hb_buffer_add_utf*().  Any other
manipulation can happen in user callbacks.  No need for this.

Behdad Esfahbod 976c8f4552 New API: hb_buffer_[sg]et_replacement_codepoint() 
With this change, we now by default replace broken UTF-8/16/32 bits
with U+FFFD.  This can be changed by calling new API on the buffer.
Previously the replacement value used to be (hb_codepoint_t)-1.

Note that hb_buffer_clear_contents() does NOT reset the replacement
character.

See discussion here:

6f13b6d62d

New API:

  hb_buffer_set_replacement_codepoint()
  hb_buffer_get_replacement_codepoint()

Behdad Esfahbod bcba8b4502 New API hb_buffer_add_codepoints()

This is like what hb_buffer_add_utf32 used to be until a couple
commits ago.
