Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
This reverts commit c9eb8f82e9.
The change caused "implicit declaration" warning and actual segfault.

Add encoding conversion (transcoding) from UTF-8 to CESU-8
and back. CESU-8 is an encoding similar to UTF-8, but encodes
codepoints above U+FFFF as two surrogates, these surrogates
again being encoded as if they were UTF-8 codepoints. This
preserves the same binary sorting order as in UTF-16. It is
also somewhat similar (although not exactly identical) to an
encoding used internally by Java.
This completes issue #15995.

Unicode Version 12.1.0 adds one single character, U+32FF SQUARE ERA NAME REIWA,
for the new Japanese era starting on May 1st. 12.1.0 will be finalized only on
May 7th, so we go with the beta version because further changes in the data we
need are highly unlikely, and we want to make sure Ruby is ready for the new era.
* common.mk: change UNICODE_VERSION to 12.1.0, UNICODE_BETA to YES
* enc/unicode/12.1.0, enc/unicode/12.1.0/casefold.h, enc/unicode/12.1.0/name2ctype.h:
add directory and generated data files for new version
* lib/unicode_normalize/tables.rb: update for new character
* test/ruby/test_regexp.rb: add test for character property age=12.1
* test/test_unicode_normalize.rb: add test for NFKC decomposition of new character
This (mostly) completes issue #15195.

The modern Georgian script is special in that it has an 'uppercase'
variant called MTAVRULI which can be used for emphasis of whole words,
for screamy headlines, and so on. However, in contrast to all other
bicameral scripts, there is no usage of capitalizing the first letter
in a word or a sentence. Words with mixed capitalization are not used
at all.
We therefore implement special behavior for String#capitalize. Formally,
we define String#capitalize as first applying String#downcase for the
whole string, then using titlecase on the first letter. Because Georgian
defines titlecase as the identity function both for MTAVRULI ('uppercase')
and Mkhedruli (lowercase), this results in String#capitalize being
equivalent to String#downcase for Georgian. This avoids undesirable
mixed case.
* enc/unicode.c: Actual implementation
* string.c: Add mention of this special case for documentation
* test/ruby/enc/test_case_mapping.rb: Add two tests, a general one
that uses String#capitalize on some (including nonsensical)
combinations of MTAVRULI and Mkhedruli, and a canary test to
detect the potential assignment of characters to the currently
open slots (holes) at U+1CBB and U+1CBC.
* test/ruby/enc/test_case_comprehensive.rb: Tweak generation of
expectation data.
Together with r65933, this closes issue #14839.

In the function onigenc_unicode_case_map() in enc/unicode.c, deal
with the case that the ONIGENC_CASE_IS_TITLECASE flag is set on
lowercase characters. This is in preparation for Georgian Mtavruli,
which are uppercase but not titlecase, in Unicode 11.0.0.

In ASCII, 'a' is bigger than 'A'. Which means 'A' - 'a' is a negative
number (-32, to be precise). In C, the type of 'a' and 'A' are signed
int (cf: ISO/IEC 9899:1990 section 6.1.3.4). So 'A' - 'a' is also a
signed int. It is `(signed int)-32`.
The problem is, OnigCodePoint is unsigned int. Adding a negative
number to a variable of OnigCodepoint (`code` here) introduces an
unintentional cast of `(unsigned)(signed)-32`, which is
4,294,967,264. Adding this value to code then overflows, and the
result eventually becomes normal codepoint.
The series of operations are not a serious problem but because
`code >= 'a'` holds, we can `(code - 'a') + 'A'` to reroute this.
