[otlayout] Fix up recent Context matching change
Commit 6b65a76b40522a4f57a6fedcbdfc5a4d736f1d3c. "end" was becoming
negative. Was trigerred by Lohit-Kannada 2.5.3 and the sequence:
U+0CB0,U+200D,U+0CBE,U+0CB7,U+0CCD,U+0C9F,U+0CCD,U+0CB0,U+0C97,U+0CB3

To be used for a variety of purposes. We save up to five characters
in each direction. No public API changes, everything is taken care

the full text + segment info (or at least some context) instead of
just passing in the segment.
Various operations (hb_buffer_reset, hb_buffer_set_length,
hb_buffer_add*) automatically reset the relevant contexts.

[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.

For two reasons:
1. User can always call hb_buffer_pre_allocate() themselves, and

reallocs is limited to a small number (~3) anyway. This just makes the
API cleaner.

[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.

While the cluster fields of the glyph string are usually sorted, they

monotonic and in which direction. Not sure it's worth it though.
