SERVER-12127 migrate js tests to jscore suite when not related to writes

Added relevant getLastError tests to jstests/gle/core
omit dbadmin.js from smalloplog suite; calls CloseAllDatabases
SERVER-12873 begin dbtest file for plan ranking, add force-ixisect flag for qa
SERVER-12842 do not add filterSet to explain if solution is not available in single solution runner
Do not include cpppath/extrapath/libpath when generating output location

Otherwise, if libraries are used which have deeper paths, the ouput path
becomes really long and builds fail due to excessively long command line.

SERVER-12896 MongoRunner fixes to make multiversion tests run on Windows

The system programs either come versioned in the form of
<utility>-<major.minor> (e.g., mongorestore-2.4) or just <utility>. If
change_extension is called on this string, it will replace the minor
version component and the binary will not be found.

In pre-2.6.0rc0 versions, we did not have the server shutdown event and
the stop commands needs to use the old method of connecting on the admin
port and invoking shutdown.
