Add Latin9 (iso-8859-15) character set.
This task is a part of Sun Globalization Requirements.
Character set name
==================
MySQL character set name will be "latin9".
Collations
==========
* latin9_bin
* latin9_danish_ci - also good for Norwegian.
* latin9_general_ci - for English, French, German Dictionary, Italian, Dutch,
Portuguese, Malay. Will provide the same sorting order as latin1_general_ci.
* latin9_general_cs
* latin9_german1_ci
* latin9_german2_ci - German Phonebook.
* latin9_spanish_ci - Modern Spanish.
* latin9_swedish_ci - also good for Finnish
The default collation will be latin9_swedish_ci
Collations will have the same sorting order with the corresponding
latin1 collations.
What the reviewer looks for
===========================
The code reviewer will look for:
- Every operation that is applicable to latin1, for example converting
+ using in CHARACTER SET clause + using in introducer + finding in
information_schema.character_sets, will be applicable to latin9.
- The characters and conversions are as in these "authoritative" charts:
