1. Use reference counted stable in global pool objects instead PublicHandle's validation.
...
2. Avoid massive segfaults when closing heavily loaded server.
3. Restored logic in YValve required for correct shutdown.
4. Do not change externally visible request body when preparing it.

Fixed CORE-1620: Incorrect error message if EXECUTE STATEMENT contains empty string. It doesn't fix the "uninitialized variable" issue per se, but I'm not sure this is strictly required, as it gets initialized if the statement contains at least one character, and all cases of empty string are now caught in advance.

1) Simplify the explicit plan handling between the parser and the engine. It makes no sense to pass the join type as it's ignored internally.
...
2) Support hash joins in the plan output and in the parser. For the latter, it's just the syntax sugar, same as loop vs merge join (see above).
