New API hb_buffer_add_codepoints()
Like hb_buffer_add_utf32, but doesn't do any Unicode validation.

Fix Mongolian Variation Selectors for fonts without GDEF
Originally we fixed those in 79d1007a501fd63c0ba4d51038c513e6b8b94740.
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

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.

HB_VERSION_CHECK's comparison was originally written wrongly

without renaming it. As such, rename.

hb_version_check -> hb_version_atleast

Fix base-position when 'pref' is NOT formed
If pre-base reordering Ra is NOT formed (or formed and then
broken up), we should consider that Ra as base. This is
observable when there's a left matra or dotreph that positions
before base.
Now, it might be that we shouldn't do this if the Ra happend
to form a below form. We can't quite deduce that right now...

[indic] Don't reorder reph/pref if ligature was expanded
Normally if you want to, say, conditionally prevent a 'pref', you
would use blocking contextual matching. Some designers instead
form the 'pref' form, then undo it in context. To detect that
we now also remember glyphs that went through MultipleSubst.
In the only place that this is used, Uniscribe seems to only care
about the "last" transformation between Ligature and Multiple
substitions. Ie. if you ligate, expand, and ligate again, it
moves the pref, but if you ligate and expand it doesn't. That's
why we clear the MULTIPLIED bit when setting LIGATED.
Micro-test added. Test: U+0D2F,0D4D,0D30 with font from:
