In regparse.c:
* Reduce coode duplication by merging the almost identical functions
create_sequence_node and create_alternate_node into a new function
create_node_from_array, adding a parameter that distinguishes between
creating a list and creating an alternative.
* Streamline variable/function naming. Unicode UAX #29 uses 'sequence', but
the regular expression library uses 'list' for the same concept. Keep
'sequence' in the ccmments that are taken from UAX #29, but use 'list'
in variable names.

* unicode.c: Remove the arrays onigenc_unicode_GCB_ranges_GAZ,
onigenc_unicode_GCB_ranges_E_Base, and onigenc_unicode_GCB_ranges_Emoji,
because they are not needed anymore for Unicode 11.0.0.
* regparse.c: Remove external declarations for above arrays.

- common.mk: Change Unicode version to 11.0.0, and Emoji version to 11.0
- test/ruby/enc/test_emoji_breaks.rb: update hard-coded Emoji version
- enc/unicode/11.0.0, enc/unicode/11.0.0/casefold.h, enc/unicode/name2ctype.h:
Add generated files. Files for Unicode 10.0.0 will be removed once we are
sure 11.0.0 works.
- lib/unicode_normalize/tables.rb: Updated table.
- regparse.c: Almost completely reimplement grapheme cluster detection in
function node_extended_grapheme_cluster().

Remove unnecessary settings of node_array elements to NULL_NODE.
We can do this because we initialize the whole array to NULL_NODEs
and set everything again to NULL_NODEs when creating a sequence or
alternative node.
Also, fix an index error in the initialization of node_array.

regparse.c: In function node_extended_grapheme_cluster(), introduce function-global
array node_array and use it for sequence and alternate construction. This is done
so that in case of error, all nodes that have already been constructed can be
correctly freed. (issue #15343)

Remove code that tries to remove CR and LF from Grapheme_Cluster_Break=Control.
This code is unnecessary because Grapheme_Cluster_Break=Control already excludes
CR and LF.

Introduce new function create_alternate_node() to create an alternative node
from a list of nodes in one go. Use it once (two more uses expected).

Four more use of create_sequence_node() in node_extended_grapheme_cluster
(a few more to come).

One more use of create_sequence_node() in node_extended_grapheme_cluster
(several more to come).

Introduce a new preprocessor macro R_ERR to visually reduce repetitive code
checking for return values and going to the err: label at the end of the
function node_extended_grapheme_cluster().

There are only four patterns of the last two arguments to quantify_property_node().
By replacing the lower/upper arguments with a single char, we get more expressive
calls, the last argument directly corresponding to the quantifier that we want to
use (except for '2', which means exactly two).

In function node_extended_grapheme_cluster(), store and test
return value from create_sequence_node(). Never forget this!

In function node_extended_grapheme_cluster(),
move declaration up so that block encompasses all of the regular expression
creation that finally makes up the sequence. Having blocks like this will
be great because it directly shows the extent of code belonging to each
subexpression of the regular expression being created.

We make sure that the newly created tree and all remaining nodes passed in
in the node_array are freed.

The new function create_sequence_node() uses its second argument
(an array of Node*, from left to right, ending with NULL_NODE)
to create a sequence of expressions using node_new_list().

The new function quantify_property_node() combines the functions
create_property_node() and quantify_node(), which frequently appear together.

Refactoring: In regparse.c, extract creation of a new CClass node and
initialization using a property into a new function create_property_node().

* enc/unicode.c: moved additional Grapheme Cluster Break ranges
which depend on the Unicode version.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65087 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* regparse.c (node_extended_grapheme_cluster): as Unicode 10 has
added Grapheme_Cluster_Break properties to some characters,
remove duplicated ranges for Unicode 9.

* regparse.c (parse_char_class): initialize return values before
depth limit check. returned values will be freed in callers

* meta character \X matches Unicode 9.0.0 characters with some workarounds
for UTR #51 Unicode Emoji, Version 4.0 emoji zwj sequences.
[Feature #12831] [ruby-core:77586]
The term "character" can have many meanings bytes, codepoints, combined
characters, and so on. "grapheme cluster" is highest one of such words,
which means user-perceived characters.
Unicode Standard Annex #29 UNICODE TEXT SEGMENTATION specifies how to
handle grapheme clusters (extended grapheme cluster).
But some specs aren't updated to current situation because Unicode Emoji
is rapidly extended without well definition.
It breaks the precondition of UTR#29 "Grapheme cluster boundaries can be
easily tested by looking at immediately adjacent characters". (the
sentence will be removed in the next version)
Though some of its detail are described in Unicode Technical Report #51
UNICODE EMOJI but it is not merged into UTR#29 yet.
