Bug#28916 LDML doesn't work for utf8

and is not described in the manual
- Adding missing initialization for utf8 collations
- Minor code clean-ups: renaming variables,
  moving code into a new separate function.
- Adding test, to check that both ucs2 and utf8 user
  defined collations work (ucs2_test_ci and utf8_test_ci)
- Adding Vietnamese collation as a complex user defined
  collation example.


include/m_ctype.h:
  Renaming variable names to match collation names (for convenience).
mysys/charset-def.c:
  - Removing redundant declarations for variables declared in m_ctype.h
  - Renaming variable names to match collation names (for convenience).

  - Renaming "new" to "newcs", to avoid using C reserved word as a variable name
  - Moving UCA initialization code into a separate function
  - The bug fix itself: adding initialization of utf8 collations

  Renaming variable names to match collation names (for convenience).
strings/ctype.c:
  Increasing buffer size to fit tailoring for languages

  Adding test case
mysql-test/std_data/Index.xml:
  Adding Index.xml example with user defined collations.
mysql-test/t/ctype_ldml-master.opt:
  Adding OPT file for the test case,
  to use the example Index.xml file.
mysql-test/t/ctype_ldml.test:
  Adding test case
