A fix for
Bug#12093 "SP not found on second PS execution if another thread
drops other SP in between" and
Bug#21294 "executing a prepared statement that executes a stored
function which was recreat"
Stored functions are resolved at prepared statement prepare only.
If someone flushes the stored functions cache between prepare and
execute, execution fails.
The fix is to detect the situation of the cache flush and automatically
reprepare the prepared statement after it.
