7a20e5282e In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to 
make characteristics (and SHOW) work right, we had to separate the old
definition blob in the mysql.proc table into separate fields for parameters,
return type, and body, and handle the characteristics (like SQL SECURITY)
separately... and then reassemble the CREATE string for parsing, of course.
This is rather ugly, mostly the parser bit. (Hopefully that will be better
with the new parser.)

7bfbfc308f WL#1364: Store some environmental values with SPs and use at invokation 
sql_mode is stored and used with SPs.
sql_select_limit is always unlimited in SPs.

b27e9d6052 WL#1363: Update the mysql.proc table and add new fields. 
Also made the parsing and handling of SP characteristics
more general and extendable, and added a few ch:istics.

70ea503662 Bugfix of previous WL#1265 commit. 
Need a sp_cache_remove() function with implicit name lookup to make the WL task
to work. It's a cleaner and more convenient interface anyway...

e42a724fa7 WL#1265: Fix proper ALTER/DROP support in the SP cache. 
New sp_cache C API. When an SP is dropped, old caches (in other threads)
become invalid and are cleared.
Also, the caches in THD are only created on demand.

a8a29a39d2 Merging 4.1 into 5.0 (second pass; post-merge fixes). 
One test in subselect.test still wrong.
Had to reconstruct all errmsg.txt files completely, since auto-merge made
a mess of the lot. :-(

c908b555ff Fixed the old kludge for pre-loading functions and made it more efficient 
using a hash table instead (and made it work with lex pointers).
Some additional code cleanup too.

9f14ae7516 sp_head now has its own mem_root (WL#961). 
Also fixed some difficult memory leaks that became apparent
in this task.

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.

ca2e77ca7a Made stored FUNCTION invokation work almost always. Still buggy and unstable, and 
various known problems, but good enough for a checkpoint commit.

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...

77b671f594 Moved create/find/drop functions to a separate files (sp.cc,sp.h). 
Fixed backpatching of forward jumps.
Implemented LOOP, WHILE, REPEAT (temporarily known as SPREPEAT).

Known bug: Expression evaluation still not quite ok (e.g. "x > 0"),
which is why IF and CASE is not yet implemented.
