Fix mdb_reader_pid().

Treat unexpected errors as "don't know".  Invert Pidcheck return
value, so nonzero including error codes = "the process may exist".

On Windows: Catch exited but still existing processes.  Handle
undefined PROCESS_QUERY_LIMITED_INFORMATION.
On Unix: don't trust F_GETLK error to leave the input alone,
the fcntl() doc seems unclear.

mdb_drop(): State what to do rather than what will be done, since
closing the handle could otherwise be read as happening even at failure.
