[API] Add hb_buffer_add_latin1()
This is by no ways to promote non-Unicode encodings. This is an entry
point that takes Unicode codepoints that happen to all be the first
256 characters and hence fit in 8bit strings. This is useful eg in Chrome
where strings that can fit in 8bit are implemented that way, and this
avoids copying into UTF-8 or UTF-16.
Perhaps we should rename this to hb_buffer_add_codepoints8(). I'm also
curious if anyone would be really interested in hb_buffer_add_codepoints16().
Please discuss!

When matching second glyph of kerning pairs, use bsearch

Add a handcoded bsearch instead of previous linear search.
This doesn't show much speedup though, apparently we spend the
bulk of the time somewhere before here.

Change New Tai Lue shaping engine from SEA to default
This is to reflect the UTC decision to change the encoding model of
New Tai Lue from logical to visual to be similar to Thai, Lao, and
Tai Viet: http://www.unicode.org/L2/L2014/14250.htm#141-C26
The visual encoding is already the current practice of encoding New
Tai Lue on the web anyway:

[ft] Don't set font ppem
For discussion see:
http://lists.freedesktop.org/archives/harfbuzz/2012-April/001905.html
Over time we have had added NO_HINTING all over the place in hb-ft. Finish it off.
Not setting ppem on hb-font disables get_contour_point() calls which is good anyway.

[ft] Add hb_ft_face_create_referenced() and hb_ft_font_create_referenced()
When I originally wrote hb-ft, FreeType objects did not support reference
counting. As such, hb_ft_face_create() and hb_ft_font_create() had a
"destroy" callback and client was responsible for making sure FT_Face is
kept around as long as the hb-font/face are alive.
However, since this was not clearly documented, some clienets didn't
correctly did that. In particular, some clients assumed that it's safe
to destroy FT_Face and then hb_face_t. This, indeed, used to work, until
45fd9424c723f115ca98995b8f8a25185a6fc71d, which make face destroy access
font tables.
Now, I fixed that issue in 395b35903e052aecc97d0807e4f813c64c0d2b0b since
the access was not needed, but the problem remains that not all clients
handle this correctly. See:
https://bugs.freedesktop.org/show_bug.cgi?id=86300
Fortunately, FT_Reference_Face() was added to FreeType in 2010, and so we
can use it now. Originally I wanted to change hb_ft_face_create() and
hb_ft_font_create() to reference the face if destroy==NULL was passed in.
That would improve pretty much all clients, with little undesired effects.
Except that FreeType itself, when compiled with HarfBuzz support, calls
hb_ft_font_create() with destroy==NULL and saves the resulting hb-font on
the ft-face (why does it not free it immediately?). Making hb-face
reference ft-face causes a cycling reference there. At least, that's my
current understanding.
At any rate, a cleaner approach, even if it means all clients will need a
change, is to introduce brand new API. Which this commit does.
Some comments added to hb-ft.h, hoping to make future clients make better
choices.

Avoid accessing layout tables at face destruction
"Fixes" https://bugs.freedesktop.org/show_bug.cgi?id=86300
Based on discussion someone else who had a similar issue, most probably
the user is releasing FT_Face before destructing hb_face_t / hb_font_t.
While that's a client bug, and while we can (and should) use FreeType
refcounting to help avoid that, it happens that we were accessing
the table when we didn't really have to. Avoid that.

Fail blob creation if length overflows or is too large
Fail if blob start plus length overflows; or if blob length
is greater than 2GB. It takes a while for fonts to get to that
size. In the mean time, it protects against bugs like this:
http://www.icu-project.org/trac/ticket/11450
Also avoids some weird issues with 32bit vs 64bit systems
as we accept length as unsigned int. As such, a length of
-1 will cause overflow on 32bit machines, but happily
accepted on a 64bit machine. Avoid that.

API: Do not clear buffer-flags in hb_buffer_clear_contents()
After 763e5466c0a03a7c27020e1e2598e488612529a7, one doesn't
need to set flags for different pieces of text. The flags now
are something the client sets up once, depending on how it
actually uses the buffer. As such, don't clear it in
clear_contents().
Tests updated.

[coretext] Minor
It's hard to handle all possible NULL returns from CoreText. Add one
more...

[coretext] Use input clusters
Before, this shaper was returning UTF-16 cluster indices instead of
returning whatever cluster values the user had had set up in the buffer.
Ouch!

[coretext] Fix buffer resize handling
We can't really resize buffer and continue in this shaper as we are
using the scratch buffer for string_ref and log_cluster. Restructure
shaper to retry from (almost) scratch.
