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.

Set subDB DBI=parent DBI, fix MDB_DUPSORT delete.
...
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.

Clean up and simplify mdb_page_search().
...
Only named DBs can have DB_STALE, and they do not use MDB_PS_MODIFY.
Replace magic key values with flags. Drop duplicated comments at
mdb_page_search_root() vs. mdb_page_search(), and rephrase.

Allow mdb_env_set_mapsize() on an open environment

is done where the first of the multiple values matches the existing
value, the put would return SUCCESS without writing any of the
values. Fixed to loop to the next value as intended.
