Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add options to control DataAccessProvider, allow to turn off use of file memory mapping in particular to solve potential sharing violation (os file handle gets released on MappedByteByffer being GC'd, not on FileChannel.close())
