* feaLib: limit language statements to 1 feature block
language exclude_dflt statements should only apply to lookups
defined in their feature block and not to lookups defined
in previous blocks sharing the same feature tag
* feaLib: add BuilderTest::test_FeatureFile_multiple_feature_blocks
Fixed encoding error in subset tool in Windows which system default codepage isn't 65001.
For Example:
When windows default codepage is 936, the command like 'pyftsubset myfont.ttf --text-file=mytextfile.txt' will throw an exception.
In the upstream google/brotli, if the `decompress` function receives an empty byte
string, it returns a brotli.error; whereas in 'brotlipy' it does not raise but
returns an empty string b"":

This test case asserts that when 'totalCompressedSize' in the WOFF2 header is
incorrectly set, the woff2 reader fails -- either because the brotli decoder
raises an exception, or it returns a string whose length is not the one expected.

Previously the warning message was wrong (probably a regression)
as it was reporting the the length of all kern data as "excess".
Fixing that, I see 4 bytes excess in Calibri. Up to 4 is alright,
since many compilers add padding and wrongly add 4 instead of 0
sometimes.
Where more than one run is used, it's only the first run's first point
that is absolute, all other values are relative.
Similar fix landing in FreeType soon. Fixes lizzard glyph (glyphname
"dollar") in Zycon.
Changed the merge algorithm to properly handle cmap subtables
of type 4 and 12 with platform id and encoding ids of 3/1 and 3/10
respectively. All other subtables are not merged and ignored.
The resulting merged cmap table includes a subtable of format 4/3/1
and a format 12 subtable iff there are mappings outside of the BMP.
If one font has two codepoints that point to the same glyph,
and another font has the same code points pointing to two other glyphs,
keep the behavior where the first replacement glyph is stored in 'locl'
and output the third glpyh (or more) to let the user know that they were
dropped, instead of failing to merge the font.

Before, if someone tried to set the language before setting the script
a None/language language system would be created (with actual tag
"None" stored in the feature table). This defaults to tag DFLT and
fails when a non-dflt language is set for DFLT, since that's illegal.
This is to fix what I think was a misunderstanding of the exclude_dflt
keyword (and the implicit include_dflt option active by default).
Rather than including the following lookups in the default language
systems, I think it is used to include the lookups specific to default
language systems in the system defined by the current language
statement. Thus instead of registering a lookup in all default
systems when include_dflt is true, we should exclude the lookups
registered with default systems from the current system when
include_dflt is false.
