659305fe0a Use byte indices instead of char indices for text runs 
Replace character indices with UTF-8 byte offsets throughout the code dealing
with text shaping and breaking.  This eliminates a lot of complexity when
converting from one to the other, and interoperates better with the rest of
the Rust ecosystem.

dba878dfb2 Remove unneeded add_nonglyph_for_char_index 
This is a no-op, since a "non-glyph" is simply `GlyphEntry(0)`. This is the
same as `GlyphEntry::initial()`, which all the entries are already initialized
to.

97a58e9689 Don't assume the first glyph is part of the first char 
Shaper::save_glyph_results incorrectly starts its loop by setting glyph_span
to a length of 1.  This means that the `if glyph_span.len() == 0` test in the
inner loop will never succeed.

Instead the glyph span should start out empty, and a glyph should be added only
as the corresponding char is found.  For comparison, see the Gecko code this
was ported from:

924d804583 Move '&&' to the end of the previous line. 
Following https://github.com/servo/servo/issues/10692 this is just a
formating change to satisfy a new tidy requirement of not having '&&' at
the beginning of a line.

Harfbuzz now renders tabs with a "missing character" glyph by default, so we
need to filter them out ourselves after computing an advance.

5fdaba05a6 layout: Implement text-align: justify and text-justify per 
CSS-TEXT-3 § 7.3.

`text-justify: distribute` is not supported.

The behavior of `text-justify: none` does not seem to match what Firefox
and Chrome do, but it seems to match the spec.

Closes #213.

505159a464 Import the util crate as util rather than servo_util. 
This used to conflict with the util crate from the standard library, which
has long since been removed.

The import in layout has not been changed because of a conflict with the
util mod there.
