Docs for SERVER-15723: Avoid G_X lock for rename_collection within database

XMLWordPrintableJSON

      Documentation Request Summary:

      Our documentation says that all operations on the database are blocked during the rename. Now this is only true for cross-database renames.

      Engineering Ticket Description:

      Probelm:

      See https://github.com/mongodb/mongo/blob/master/src/mongo/db/commands/rename_collection.cpp#L113

                  Lock::GlobalWrite globalWriteLock(txn->lockState());

      Solution:
      Scope this lock as a DB_X when renaming within a database. Renaming between databases probably still requires a G_X or perhaps two DB_X locks.
