(cleanups, leaks fixed)

cleanup before throwin away DYNAMIC_ARRAY for event storage,
once reallocated I get dangling pointers so that's not good.
solution will be found however ;)

QUEUE implementation working now. this should be ready more or less
for testing once the debug output is being cleaned and some things
around DYNAMIC_ARRAY are cleaned
- fix handling in case of errors that lead to crashes, now no more crashes
  in case of table corruption and such.

- handle better non-latin1 identifiers

- fix a bug introduced with last commit ALTER EVENT a RENAME TO b; failed
- misc

(strip m_ as prefix from member variables' names)

make more independent of SP

updated sources

- split into several files
- forbid parallel execution (before analyse is done how to make it possible)
  because the same sp_head instance cannot be executed in parallel
- added GPL headers
- changed EVENT_ACL to be per DB variable
- fixed minor problems

The previous variant where it was a specific ha_partition method
only worked for the partition handler. It was unfortunately called also
for the NDB handler and in this case it called a random method in the
NDB handler with random input.

Its funny, I am reading through the forums and someone asks "Can I please have a REPLACE INTO, instead an INSERT INTO?" and I remember how often I have used a sed script to modify MySQL dumps to have exactly that.
So, use --replace and instead of getting INSERT INTO you will INSTEAD get REPLACE INTO. Buyer beward, REPLACE is a MySQL SQL, so you will not end up with a dump that can be used for other databases.

Though I hear you could just use a sed line to modify it back :)

Update version number to 5.1.4-alpha
