Optimized hash function for lock manager and hash join
Notes:
- lock print extension is not backported
- Alex, please review linux build. I did not include changes in builds/posix/make.rules here as i'm not sure it is required
Now all plug-ins have the same root\install folders.
It should fix CORE-4581 and related issues.
MSVC10 and MSVC12 builds are updated, Posix and Darwin builds will follow.
