Behdad Esfahbod f22b7e7778 [Indic] Track base position when reordering things
Ouch, how did things ever work without this?!  The added test that has a
dot-reph as well as a pre-base reordering Ra perfectly demonstrates the
bug (tested with Nirmala font from Win8 for example).  Testing suggests
that Win8 shaper has the *exact* same bug / behavior that we used to
have.  Odd.

Behdad Esfahbod 5898fa94d1 Don't use $(ENV)
As reported by Peter Breitenlohner:

I think this is a very bad idea because ENV is used to specify a startup
file to be read by some/all shells.

Behdad Esfahbod 0c7df22228 Add buffer flags
New API:

	hb_buffer_flags_t

	HB_BUFFER_FLAGS_DEFAULT
	HB_BUFFER_FLAG_BOT
	HB_BUFFER_FLAG_EOT
	HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES

	hb_buffer_set_flags()
	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/...

Behdad Esfahbod 10b88d89ef Add Ethiopic test case
This sequence: U+120B,U+135F,U+120B with the Nyala font from Win7
exposes a GPOS bug in Uniscribe, in that the positioned mark is wrongly
moved as a result a following kern.

This is the one "failure" in the Ethiopic test suite :-).

Behdad Esfahbod 166b5cf7ec [Indic] Find syllables before any features are applied
With FreeSerif, it seems that the 'ccmp' feature does ligature
substituttions.  That was then causing syllable match failures.  We now
find syllables before any features have been applied.

Behdad Esfahbod efb8d3eb71 Fixup test failure reporting
After we implemented dotted-circle, we were still ignoring any tests
that had dottedcircle in it for any of the shapers.  That meant that if
we wrongly outputted dottedcircle, the test was being ignored.  Ouch!

Fixing that shows regressions across the board.  Most are Uniscribe
bugs: NOT inserting dotted-circle when it should.  Some are arou
machine bugs.  This is in fact a nice way to catch Indic-machine
deficiencies and when I fix the regressions, our clusters should be
much closer to Uniscribe.  For now, we regressed from:

Behdad Esfahbod a973b5ce86 [GSUB] Further adjustments to mark-attachment vs ligation interaction
The d1d69ec52e change broke Kannada badly,

with the matra.  Adjust for that.  See comments.

Behdad Esfahbod c3f769ba09 [Indic] Ignore Uniscribe output containing two zero-width space glyphs
Uniscribe is buggy and sometimes /eats/ a mark next to a non-joiner.
Most of Malayalam failures where actually hitting this bug.

Ignore test output with two zero-width space glyphs.  This is a hack
until we build up the test suite infrastructure better.

Behdad Esfahbod 88f413b56f [Indic] Implement Reph+Ya-Phalaa interaction
The sequence Ra,H,Ya in Bengali is ambigious and Unicode encoded that to
get Ya-Phalaa, one would place ZWJ before Halant.  Ie. a ZWJ,H sequence
requests subjoining, while a H,ZWJ requests Half form.  Implement that.
