[Indic] Relax grammar
...
Now that we insert dotted-circle, tests break more easily when our indic
machine breaks.
In particular, a few Devanagari tests were having sequences like
"C,H,ZWJ,N", and because of the ZWJ the Nukta does NOT get reordered to
before the Halant as the grammar used to expect... Fixup.
Another case is as simple as "C,ZWJ,SM".

Unfortunately if the font has GPOS and 'mark' feature does
not position mark on dotted-circle, our inserted dotted-circle

here.
If there is no GPOS however, the fallback positioning kicks in
and sorts this out.

[Indic] Implement dotted-circle insertion for broken clusters
...
No panic, we reeally insert dotted circle when it's absolutely broken.
Fixes most of the dotted-circle cases against Uniscribe. (for Devanagari
fixes 80% of them, for Khmer 70%; the rest look like Uniscribe being
really bogus...)
I had to make a decision. Apparently Uniscribe adds one dotted circle
to each broken character. I tried that, but that goes wrong easily with
split matras. So I made it add only one dotted circle to an entire
broken syllable tail. As in: "if there was a dotted circle here, this
would have formed a correct cluster." That works better for split
stuff, and I like it more.

Port Arabic fallback ligating to share code with GSUB
...
This will eventually allow us to skip marks, as well as (fallback)
attach marks to ligature components of fallback-shaped Arabic.
That would be pretty cool. I kludged GDEF props in, so mark-skipping
works, but the produced ligature id/components will be cleared later
by substitute_start() et al.
Perhaps using a synthetic table for Arabic fallback shaping was a better
idea. The current approach has way too many layering violations...

[GSUB] Don't set new lig_id on mark ligatures
...
If two marks form a ligature, retain their previous lig_id, such that
the mark ligature can attach to ligature components...
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=676343
In fact, I noticed that we should not let ligatures form between glyphs
coming from different components of a previous ligature. For example,
if the sequence is: LAM,SHADDA,LAM,FATHA,HEH, the LAM,LAM,HEH form a
ligature, putting SHADDA and FATHA next to eachother. However, it would
be wrong to ligate them. Uniscribe has this bug also.

[Indic] Improve Sinhala base algorithm and reph positioning

Sinhala does not have half forms. And most (all?) consonants can be

Hence switch the base algorithm to categorize with Khmer, start search
at start, and stop at a ZWJ.
Also, mark all pos=base consonants after base to be subjoined. Mark
base itself to have pos=base.
Finally, adjust Sinhala's reph position to after-main.
Brings down Sinhala failures from 455 to 328 (0.120656%).

- For Thai, with the Angsana New font from Win7, I see 54 failures out
of over 4M tests (0.00129107%). Of the 54, two are legitimate
reordering issues (fix coming soon), and the other 52 are simply
Uniscribe using a zero-width space char instead of an unknown
character for missing glyphs. No idea why. The missing-glyph
sequences include one that is a Thai character followed by an Arabic
Sokun. Someone confused it with Nikhahit I assume!
- For Lao, with the Dokchampa font from Win7, 33 tests fail out of
54k (0.0615167%). All seem to be insignificant mark positioning
with two marks on a base. Have to investigate.

In Sinhala, Rakar is formed by Al-Lakuna,ZWJ,Ra. If you put that at the
end of a Consonant,Matra syllable, you get a dotted-circle from
Uniscribe. Apparently adding a ZWJ before the Al-Lakuna "fixes" that.
And people have been encoding that sequence... So, allow a forced
"ZWJ,Virama,ZWJ,Ra" sequence at the of syllables.

own. And we do. But it will interact with the Halant before it. So

Add support for atomic int and mutex on Apple systems

So, apparently there's no atomic int 'get' method on Apple. You have to
add(0) to get. And that's not const-friendly. So switch inert-object
checking to a non-atomic get. This, however, is safe, and a negligible
performance boost too.

Fallback to Latin script if the font has no other usable scripts
...
Patch and description from Jonathan Kew:
It turns out that some legacy Thai fonts provide OpenType substitution
features to implement mark positioning, but (incorrectly) put those
features/lookups under the 'latn' script tag instead of using 'thai' (or
possibly 'DFLT'). See
https://bugzilla.mozilla.org/show_bug.cgi?id=719366 for an example and
more detailed description.
Although this is really a font bug, I suggest that we could improve the
rendering of such fonts by looking for the 'latn' as a fallback if
neither the requested script nor "default" is found in
hb_ot_layout_table_choose_script. Suggested patch against harfbuzz
master is attached.
This does _not_ affect the other kind of legacy Thai font, where custom
code to support vendor-specific PUA codepoints would be needed. I'm not
keen to go down that path; IMO, such fonts should be ruthlessly stamped
out in favour of standards-based solutions. :)

[API] Changes to main shape API
...
hb_shape() now accepts a shaper_options and a shaper_list argument.
Both can be set to NULL to emulate previous API. And in most situations
they are expected to be set to NULL.
hb_shape() also returns a boolean for now. If shaper_list is NULL, the
return value can be ignored.
shaper_options is ignored for now, but otherwise it should be a
NULL-terminated list of strings.
shaper_list is a NULL-terminated list of strings. Currently recognized
strings are "ot" for native OpenType Layout implementation, "uniscribe"
for the Uniscribe backend, and "fallback" for the non-complex backend
(that will be implemented shortly). The fallback backend never fails.
The env var HB_SHAPER_LIST is also parsed and honored. It's a
colon-separated list of shaper names. The fallback shaper is invoked if
none of the env-listed shapers succeed.
New API hb_buffer_guess_properties() added.

Shapers now can request segmented feature application by calling

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.

[API] Make get_glyph() callback return a boolean
...
We need to know whether the glyph exists, so we can fallback to
composing / decomposing. Assuming that glyph==0 means "doesn't exist"
wouldn't work for applications like Pango that want to use different
"doesn't exist" glyph codes for different characters. An explicit
return value fixes that.

[API] Add hb_language_get_default()

It uses locale information to detect default language. It's used by
hb_shape() whenever language is not set on the buffer.
Not sure how to properly test it in the test suite. Tested by observing
that with DejaVu Sans we select the proper local glyph version for U+431
under Serbian locale. See http://www.pango.org/ScriptGallery

[buffer] Remove wrong optimization
...
While the cluster fields of the glyph string are usually sorted, they
wouldn't be in special cases (for example for non-native direction).
Blindly using bsearch is plain wrong. If we want to reintroduce this
optimization we have to make sure we know the buffer clusters are
monotonic and in which direction. Not sure it's worth it though.
