hb-shape --output-format=json
Deserialization API is added, but not implemented yet.

[Thai] Implement PUA-based fallback shaping

As explained here:
http://linux.thai.net/~thep/th-otf/shaping.html
Our output now matches Uniscribe for old fonts (eg. XP Tahoma) with no
Thai GSUB table.

[Indic] Don't move virama with left matra
...
This is important for the Sinhala U+0DDA split matra since it decomposes
to U+0DD9,U+0DCA where U+0DD9 is a left matra and U+0DCA is the virama.
We don't want to move the virama with the left matra.
TEST: U+0D9A,U+0DDA
Note that we were already doing this in the Uniscribe bug compatibility
mode. We now do it all the time.

HB_BUFFER_FLAGS_DEFAULT
HB_BUFFER_FLAG_BOT
HB_BUFFER_FLAG_EOT
HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES

hb_buffer_get_flags()
We use the BOT flag to decide whether to insert dottedcircle if the
first char in the buffer is a combining mark.
The PRESERVE_DEFAULT_IGNORABLES flag prevents removal of characters like
ZWNJ/ZWJ/...

Had to do some refactoring to make this happen...
Under uniscribe bug compatibility mode, we still plit them
Uniscrie-style, but Jonathan and I convinced ourselves that there is no
harm doing this the Unicode way. This change makes that happen, and
unbreaks free Sinhala fonts.

[hb-shape] Adjust postioning output format

1. If there is any offset (x or y), print out both x and y offsets.
2. Always print out the advance in the major direction of the buffer.
Ie. even for zero-advance glyphs, print a "+0". This is more intuitive.
