Bug Fixes

Issue 2034, Issue 2383, Issue 2702: Fix race condition in change merge queue when using Cherry-Pick submit strategy.

There was a race in the merge queue between changes submitted via the UI, and merges scheduled by the background merge queue reload.

This resulted in multiple submit actions being scheduled, leading to corrupt changes.

Execute cherry-pick submit DML operations in a database transaction boundaries. In combination with implemented transaction management for Jdbc dialects it solves the problem recovering from collisions between interactive actions and background jobs.
In gwtorm the LIMIT clause was only honored when followed by a constant integer.

When followed by a placeholder "?" it wasn’t included in the generated database query. This caused poor performance when moving to the next change page for very big projects.
Fix sporadic SSHD handshake failures (SSHD-330).
