This adds better support for Arabic script languages, Armenian,
Catalan, Hebrew, Kannada, Malayalam, Polish, Tamil, and Telugu by
adding various hyphenation types and edits appropriate for the
locales.

For Arabic script languages, soft hyphens act transparently with
regard to joining: If a line is broken at a soft hyphen where the two
characters around the soft hyphen were joining each other before,
they will continue to appear joining if the line is broken at the
soft hyphen and a hyphen glyph is inserted.  This is needed for
Central Asian languages such as Uighur.

For Armenian, U+058A ARMENIAN HYPHEN is used for line breaks caused
by either automatic hyphenation or soft hyphens.

For Catalan, nonstandard line breaks are implemented for "l·l", which
hyphenates as "l-/l".

For Polish, when there is a line break at a hyphen, the hyphen is
repeated at the next line.

For the South Indic languages, when breaks happen due to soft breaks
or automatic hyphenation, no visible hyphen is inserted, although a
penalty is added.

For Hebrew, support for using U+05BE HEBREW PUNCTUATION MAQAF has
been implemented, but it's turned off pending confirmation of
desirability.

Also, hard hyphens, which previously had no penalty added for
breaking the line after them, now have the same penalty as an
automatic or soft break, with the difference that no hyphen is
inserted when they break.

Finally, some bugs have been fixed with hyphenating multiscript and
multi-font words.

Let's use shared_ptr since manual ref counting can be a bug-prone and
using the global mutex inside destructor is not useful for some time.

The original CL was reverted due to conflicting with another CL submitted
before.

Here is the original commit message of reverted change.

This lays the groundwork for variation settings support.
Since we should regard different variations of a font as different fonts, we
need to create new typefaces. To reuse the same instance of MinikinFont, as
much as possible, FontFamily::createFamilyWithVariation now reuses an
existence instance, while incrementing the reference count.

The difference is adding clearElementsEithLock to Font class which
is necessary to delete Fonts object outside of minikin. This method
should be removed once http://b/28119474 is fixed.

Here is original commit message of reverted change.

This lays the groundwork for making SparseBitSet serializable.
FontFamily.addFont is only used when the FontFamily is constructed.
Thus, instead of calling FontFamily.addFont multiple time, passes
Font list to the constructor. By this change, FontFamily can be
immutable now.

By making FontFamily immutable, We can create FontFamily with
pre-calculated SparseBitSet.

Change language score calculation in the calculation of the font family.
Instead of language and script matching, a match in subtag is added.
In addition, a match in subtag has a higher priority than a match in
script. The score levels are divided into 5 score levels and the limit
of the number of font languages is changed to 12 from 17. Multiple
languages selection rule could to be added in the future.

minikin_tests was copying its test data to
$OUT/data/DATA/nativetest/minikin_test, and then packaging that with
LOCAL_PICKUP_FILES=$OUT/data/DATA, which would also pick up anything
any other module copyied to $OUT/data/DATA.  $OUT/data/DATA isn't
where the tests expect to find their data, they look in
/data/nativetest/minikin_test.  Copy the files to the intermediates
directory instead.

A future change will install LOCAL_PICKUP_FILES for local builds
to the correct place, so adb sync and
adb shell /data/nativetest/minikin_tests/minikin_tests will run the
tests.

This is partial revert of Iced1349e3ca750821d8882c551551f65bb569794.

Due to sorting of target family vectors, the font family order from XML
settings file is broken. Making unique operation stable doesn't fix the
issue completely since some font families are appended for the fallback
which also breaks the original order.

By this change, itemization becomes 3x slower than before if variation
selector is appended.
