SERVER-17718 deprecate showDiskLoc()

The showDiskLoc() shell helper is now an alias for showRecordId(). The server still
accepts $showDiskLoc for OP_QUERY style find operations. For find command, the showDiskLoc
argument has been renamed to showRecordId.

Also renames the $diskLoc field returned in the resulting documents to $recordId. Unlike
$diskLoc, the $recordId field reports a single 64 bit integer rather than separately reporting the
high-order 32 bits and low-order 32 bits, which have MMAPv1-specific meaning of file and offset.
