Fix for bug #46456 [Ver->Prg]: HANDLER OPEN + TRUNCATE + DROP
(temporary) TABLE, crash
Problem: if one has an open "HANDLER t1", further "TRUNCATE t1"
doesn't close the handler and leaves handler table hash in an
inconsistent state, that may lead to a server crash.
Fix: TRUNCATE should implicitly close all open handlers.
Doc. request: the fact should be described in the manual accordingly.
