Mostly needed for Monty for him getting notion what needed for triggers 
from new .FRM format. 

Things to be done:
- Right placement of trigger's invocations
- Right handling of errors in triggers (including transaction rollback)
- Support for priviliges
- Right handling of DROP/RENAME table (hope that it will be handled automatically
  with merging of .TRG into .FRM file)
- Saving/restoring some information critical for trigger creation and replication
  with their definitions (e.g. sql_mode, creator, ...)
- Replication

Already has some known bugs so probably not for general review.

Replication of charsets and timezones should shortly be changed to not need ONE_SHOT
(but 5.0 should still be able to read it, to be able to replicate 4.1 masters).

Note: The following tests fails
- fulltext (Sergei has promised to fix)
- rpl_charset (Guilhem should fix)
- rpl_timezone (Dimitray has promised to fix)

Sanja needs to check out the calling of close_thread_tables() in sp_head.cc

charged sql/sql_db.cc only
(
changed length in mysql_create_db to path_len
so as it was calculated in the first unpack_dirname
in my previous fix for Bug #4378
'"create database IF NOT EXISTS thing" returns an error'
)

as after effect of fix for Bug #4378 
'"create database IF NOT EXISTS thing" returns an error' 

(avoided an unpack_dirname and 
 changed strcat into strmake)

  Define cxa_pure_virtual to print error message and DBUG_ASSERT:
  calls to pure virtual methods should not go unnoticed.
