a5780a4815 Fixed BUG#336: Subselects with tables does not work as values for local SP variables 
and BUG#1654: Stored Procedure Crash if contains subquery and set function

Disallowed subselects in RETURN (for FUNCTIONs) and SET of local variables.
The latter should work, but turned out to be difficult to fix, so we just
disallow it for the time being.

5e46a05960 Fixed BUG#1874: Don't call fix_fields() indiscriminately, it resets null_value 
for some items, which made aggregates like MIN(), MAX() and SUM() fail.

c4871b240d Fixed BUG#1862 (flush table in SPs didn't work). 
Fixed various bugs: setting local variables to NULL, SELECT INTO var now actually
might work, SELECT INTO with not row now gives a "no data" warning (instead of
the "empty query" error), etc.
Updated test cases accordingly.

8049daf202 Made FUNCTIONs work in insert and select queries, as well as nested function invocations. 
Had to add a cahing mechanism which is in parts an ugly kludge, but it will be
reworked once the real SP caching is implemented.

16cff7e75d A small step forward. Fixed a few bugs and made string type functions work,

ca2e77ca7a Made stored FUNCTION invokation work almost always. Still buggy and unstable, and

d8c75ec8aa Most of the groundwork for sprint task 729 (implement FUNCTIONs). 
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...
