Set MDB_xcursor DB_DIRTY, clear md_name.

Both were unused and md_name was unmaintained -- except
mdb_cursor_touch(xcursor) would abuse md_name as a key to
touch MAIN_DBI if it could somehow get passed ! DB_DIRTY.

xcursor DBIs were parent DBI+1 for debugging. Instead output
-(parent DBI). Fixes a crash in mdb_cursor_del0()'s xcursor
tracking, it forgot to subtract 1 for C_SUB cursors.
