In MySQL when the mapping for space is changed to something other than
0x20 by defining a different collation, then space is not ignored when
comparing two strings.
This was happening because the function that performs the comparison
of two strings while ignoring ending spaces, was comparing the collation
value of a space with the ascii value of the ' ' character. This should
be changed to do comparison between the collated values.
mysql-test/r/ctype_ldml.result:
Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
Result file for test case.
mysql-test/std_data/Index.xml:
Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
Added entry for new test collation in the index file.
mysql-test/std_data/latin1.xml:
Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
Added support for new collation for test.
mysql-test/t/ctype_ldml.test:
Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
Added test case to ensure trailing spaces are not ignored.
strings/ctype-simple.c:
Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
change my_strnncollsp_simple to compare collated values when checking
for trailing spaces. Currently the comparison happens between a collated
value and the ascii value.

- 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.
