reworked once the real SP caching is implemented.
mysql-test/r/sp.result:
New function tests.
mysql-test/t/sp.test:
New function tests.
sql/sp.cc:
Big rehack of mysql.proc table usage strategy and adding a function cache
mechanism, since we need to read used functions from the db before doing anything else
when executing a query. (This cache is temporary and will probably be replaced by
the real thing later.)

Expanded the mysql.proc table, reworked the find/create/drop functions
completely, added new functions for FUNCTIONs (lotta functions here :),
got rid of some unnecessary use of Item_strings while at it. Extended
the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs
coexist with UDFs.
Can now CREATE and DROP FUNCTIONs. Invoking yet to come...

Updated with info about CASCADE/RESTICT and METHOD, and some answers to questions.

statement.)
sql/sp_head.cc:

Attempted to support global user vars as OUT/INOUT parameters too, but
unfortunately we can't quite manage that yet.

single-statement procedures, rudimentary multi-statement (begin-end) prodedures
(when the client can handle it), and local variables.
Missing most of the embedded SQL language, all attributes, FUNCTIONs, error handling,
reparses procedures at each call (no caching), etc, etc.
Certainly buggy too, but procedures can actually be created and called....

Lots and lots of additions for SPs...
(Still even more missing, and no error messages...)
