This separates libTXT tests and Minikin tests and accounts for building
with an older version of ICU. Once ICU has been updated, the workarounds
for emoji handling will be removed.

Many of these fail because they assume they're being executed on Android, but
at least they build.

Here these mappings are used to convert from uppercase to lowercase,
and mk_hyb_file.py doesn't handle multi-character uppercase sequences.
Therefore, in case the sequence ßSS is encountered in a .chr.txt,
replace it internally with ßẞ.

This patch reduces about 73 kB memory.
The original SparseBitSet could contain full 32bit integers, but all of
that is not necessary for Unicode code points. By reducing the supported
range to up to Unicode maximum, U+10FFFF, we can save extra memory.
SparseBitSet holds 256-bit sliced pages and indices of them.
Previously, we needed to hold up to 2^24-1 pages for keeping 32-bit
integers.
This CL limits the number of pages to 2^16-1 (65535), so that
SparseBitSet only supports 24-bit integers now, but this is sufficient
for keeping all Unicode code points. With this change, we can change the
index integer type from uint32_t to uint16_t.

Some fonts don't have cmap subtables of Microsoft Platform ID (3) and
only have cmap subtables of Unicode Platform ID (0).

Removed Bitmap and MinikinFontFreeType classes, as well
as the Layout::draw() method.
The code was there for debugging purposes and for potential
third-party users. We no longer support third-party uses of
Minikin, since we don't know of any.

Previously, we insisted that in order for us to claim that a text variation
sequence is supported or to display it, it needs to be standardized already.
Now we accept any character as the base of a text variation sequence and
support it as far the font used to display it is not an emoji font.
Also fix a typo in a font name.
Test: Unit tests are updated and pass.

This is now done properly in ICU so we no longer need to do it ourselves.
Also updated some comments about emoji line-breaking.
Test: Existings tests for this in Minikin continue to pass.

Certain differences are still needed, since ICU appears to support
Emoji 4.0 only, while we need Emoji 5.0. But the bulk of the data is
now carried by ICU.
We no longer need the script that generates the tables, so that's
also removed.
Test: Comprehensive unit tests added.

Update emoji character data to Unicode 10.0 / Emoji 5.0 (which also
removes U+1F93B MODERN PENATHLON from the emoji base letters).
Also add unit tests for line breaking for new characters (based on
earlier work by Seigo Nonaka).
Test: All new and existing unit tests pass;
Test: Manually tested line breaking of new emojis in TextView.

The rules are updated to the latest UAX #29, with tailorings based on
the font in use: we can now use the clustering information
calculated by Layout, so we will only disallow a grapheme break if an
emoji ligature is actually formed.
Test: Unit tests have been updated and pass.
