Disable 'cswh' by default except for Arabic shaper
...
That better matches OpenType spec. Note that we enable it for all
Arabic-shaper scripts. Ie. we enable it by default for Syriac too,
but the SyriacOT spec does not require it. I think this is a more
useful compromise than special-casing for Arabic script alone.

[hb-view] Rewrite --features parsing, with range support
...
The --features parsing handles errors now. More importantly, it
allos limiting individual features to specific byte ranges. The
format is Python-esque. Here is how it all works:
Syntax: Value: Start: End:
Setting value:
"kern" 1 0 ∞ # Turn feature on
"+kern" 1 0 ∞ # Turn feature off
"-kern" 0 0 ∞ # Turn feature off
"kern=0" 0 0 ∞ # Turn feature off
"kern=1" 1 0 ∞ # Turn feature on
"kern=2" 2 0 ∞ # Choose 2nd alternate
Setting index:
"kern[]" 1 0 ∞ # Turn feature on
"kern[:]" 1 0 ∞ # Turn feature on
"kern[5:]" 1 5 ∞ # Turn feature on, partial
"kern[:5]" 1 0 5 # Turn feature on, partial
"kern[3:5]" 1 3 5 # Turn feature on, range
"kern[3]" 1 3 3+1 # Turn feature on, single char
Mixing it all:
"kern[3:5]=0" 1 3 5 # Turn feature off for range

Add script to/from ISO 15924 tag support

Also adds --script support to hb-view.
If a script tag is not known to us, we pass the ISO 15924 tag around.
Right now, the OT layer ignores that, but we can fix it to blindly
convert that to an OT script tag.

Let hb_shape() guess script and direction...
...
- Rename HB_SCRIPT_INVALID_CODE to HB_SCRIPT_INVALID
- Add HB_DIRECTION_INVALID
- Make hb_script_get_horizontal_direction() public
- Make hb_shape() guess script from buffer text (first non-common
non-inherit script) if buffer script is set to HB_SCRIPT_INVALID (this
is NOT the default.)
- Make hb_shape() guess direction from buffer script if buffer direction
is set to HB_DIRECTION_INVALID (this is NOT the default.)
- Make hb-view.c set INVALID script and direction on the buffer.
The above changes are meant to make hb-view fairly useful for uni-script
uni-direction text. The guessing behavior however is NOT the default of
hb_shape() and must be asked for explicitly. This is intended, because
the guess is not a suitable substitute to full-fledged bidi and script
segmentation. It's just a testing tool.

Bug 32274 - classic mongolian shaper
...
Add support for classic Mongolian script to the Arabic shaper.
Still work to be done around U+180E MONGOLIAN VOWEL SEPARATOR as it
should not be included in the final glyph stream the same way that
ZWNJ, etc should not appear in the final glyph stream.
But the joining part should be done.
There remains the question of how should the U+18A9 MONGOLIAN LETTER ALI
GALI DAGALGA be handled as it has General Category NSM but a letter
nonetheless. For now, our generic logic makes this a joining T instead
of joining D as other Mongolian letters are.
