Added a new method TestUtil.consumeTestData() to emulate
the exact behaviour and modified OggExtractorFileTests to
use it. Rest of the test will be fixed in follow up CLs.

This allows limiting the horizontal extension of the cues.
NOTE: So far, we only support percentages for size magnitudes.

This CL allows near-complete support to CSS selectors (I say near because not every
CSS rule applies to WebVTT).

Allow styling <v Someone>Hello</v> with ::cue(v[voice="Someone"]) { ... }.

This CL allows style blocks to reference elements. For example: we could style
a cue with text "Sometimes <b>bold</b> is not enough" with the style block
::cue(b) { ... }.

In CSS, ids are references using #. The absence of # references elements.
NOTE: If the id of a cue was "1", we support its reference with ::cue(#1).
In CSS, however, this is not valid, and the number should be escaped with
\3 as in ::cue(\31). We still do not use number escaping (and I doubt
whether we should at some point).

This CL adds the support of CSS styling in Cues through id and "universal" cue selector.
The more sophisticated selectors will be left for later, because they requier a bit more
complex logic. Also narrowed a little bit the responsibilities of the WebvttCueParser to
move some to the WebvttParser.

allow "center".
This value (and not "middle") is listed in
https://w3c.github.io/webvtt/ ( WebVTT: The Web Video Text Tracks Format, Draft
Community Group Report, 21 December 2015).
Leaving the behavior for "middle" unchanged.
It was the value listed in older drafts, e.g.
https://www.w3.org/TR/2014/WD-webvtt1-20141113/ ( W3C First Public Working
Draft 13 November 2014 )

- I think \r and \n are handled the wrong way around?
- We only expect to encounter a BOM sequence at the start of a
file, but it feels fine to automatically discard it in all
cases for simplicity. A BOM sequence doesn't mean anything in
UTF-8. See https://en.wikipedia.org/wiki/Byte_order_mark. Note
that I think the advice not to remove it on that page relates
only to the case where the file is being edited + saved.
Issue #1136

* Split findNextCueHeader and validateWebVttHeader into static methods.
This is a step toward WebVTT in HLS, where we'll need to re-use these
to peek at the top of the WebVTT file (they'll be moved into a util
class).
* Made parser robust against bad cue headers + added a test.
* Removed spurious looking assertion in WebvttSubtitle.
- Line parameter
- Added support for value and line alignment attributes.
- Support negative numbers when line is an absolute number (not a
percentage).
- Position parameter
- Added support for value and position alignment attributes
- Added support for WebVTT comment blocks
- Percentage values now accept decimal numbers (as webvtt spec states)
- Added new WebVTT tests for testing all new implemented features
- do not denormalize styles at parsing time but only put normalized style info
into TtmlNode tree. Resolve styles on demand when Cues are requested for a
given timeUs.
- create TtmlRenderUtil to have static render functions separate
- added unit test for TtmlRenderUtil
- adjusted testing strategy for unit test to check resolved style on Spannables after rendering
