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() 
Like hb_buffer_add_utf32, but doesn't do any Unicode validation.
This is like what hb_buffer_add_utf32 used to be until a couple
commits ago.

Behdad Esfahbod 3b861421a7 Fix Mongolian Variation Selectors for fonts without GDEF 
Originally we fixed those in 79d1007a50.
However, fonts like MongolianWhite don't have GDEF, but have IgnoreMarks
in their LigatureSubstitute init/etc features.  We were synthesizing a
GDEF class of mark for Mongolian Variation Selectors and as such the
ligature lookups where not matching.  Uniscribe doesn't do that.

I tried with more sophisticated fixes, like, if there is no GDEF and
a lookup-flag mismatch happens, instead of rejecting a match, try
skipping that glyph.  That surely produces some interesting behavior,
but since we don't want to support fonts missing GDEF more than we have
to, I went for this simpler fix which is to always mark
default-ignorables as base when synthesizing GDEF.

Micro-test added.

Fixes rest of https://bugs.freedesktop.org/show_bug.cgi?id=65258

It's both faster and produces smaller code.  Now I feel stupid for
not writing it this way before.

Behdad Esfahbod efe74214bb Show U+FFFD REPLACEMENT CHARACTER for invalid Unicode codepoints 
Only if the font doesn't support it.  Ie, this gives the user to
use non-Unicode codepoints as private values and return a meaningful
glyph for them.  But if it's invalid and font callback doesn't
like it, and if font has U+FFFD, show that instead.

Font functions that do not want this automatic replacement to
happen should return true from get_glyph() if unicode > 0x10FFFF.

Don't rely on bash.
