Phase 4 (final): Remove associated stored procedures when a database is dropped.

Phase 3: Made qualified names work for functions as well.

into mysql.com:/home/pem/work/mysql-5.0-merge

Had to initialize some fields in lex before parsing an SP read from
mysql.proc.

Phase 2: Make SPs belong to a DB, and use qualified names.
  As a side effect, using USE in an SP is no longer allowed.
  (It just doesn't work otherwise.)

into mysql.com:/home/pem/work/mysql-5.0

SQL SECURITY DEFINER must enforce reduced rights too, not just additional rights.

without proper locking.

Phase 1: Introduced sp_name class, for qualified name support.

"MySQL server does not detect if garbage chara at the end of query"

Allow the parser to see the garbage characters.
Garbage should cause the parser to report an error.

CONVERT3 was removed, it was for test purposes,
and rather harmful.

Made code shorter and more correct

into mysql.com:/home/mysql_src/mysql-4.1

"MySQL server does not detect if garbage chars at the end of query":

Detect garbage chars at the end of the query or at the end of a query
for a prepared statement (which happens if mysql_real_query() or mysql_prepare()
were called with a too big 'length' parameter (bigger than the real intended
length of the query: then we receive a query + garbage characters from the
client). This resulted in garbage chars written into the binlog.
Now instead the client receives something like:
'You have an error in your SQL syntax.  Check the manual that corresponds
to your MySQL server version for the right syntax to use near '!stmt'
at line 1' i.e. the server is pointing at the weird tail of the query
(this '!stmt' are the garbage chars sent by the client).
All tests pass, except mysqldump.test and ctype_utf8.test but they failed
before the patch.
