Howard Chu
4009c9ae65 Add mdb_env_copy2()
And mdb_env_copyfd2(). Perform compaction on the copy. Trims out
freed pages and renumbers data pages in sequential order. This is
more CPU-intensive since it copies and modifies data pages.

4e954f8ae8 ITS#7793 mdb_cursor_put(): Fix MDB_CURRENT.
Ignore key, broken by 5bda3565a9
and some older code.  Document and clarify MDB_CURRENT usage.

Also affects non-MDB_CURRENT put() with empty data and a key
which matches by the mdb_set_compare function but not by memcmp.

2e7130cab0 Allow mdb_env_set_mapsize() on an open environment
The caller is responsible for making sure no transactions are
active in this process before resizing. This is slightly lighter
weight than doing a full env_close/env_open cycle.

6214423163 Clarify doc: mdb_copy, nested txns, mdb_drop().
mdb_copy: Does not copy lockfile. Can trigger file growth.
mdb_txn_begin(): Clarify usage restrictions.
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.

MDB_NEXT_NODUP, MDB_PREV_NODUP: Allow for non-MDB_DUPSORT databases.
No mdb.c code changes needed.

mdb_stat.c: Use MDB_NEXT_NODUP, to avoid a crash with a DUPSORT mainDB.

b389341b4b mdb_dcmp(): Assume the database has MDB_DUPSORT.
There was little point in returning EINVAL when not: Comparing (A,B)
and (B,A) would claim (A > B && B > A), which could confuse callers.

e4af9ee5da ITS#7515 mdb_dbi_open(): Also open in parent txns.

53cf2eed90 ITS#7491 check for filled dirty page list
Very large single transactions will fail. It's not just a problem when
nested transactions are used. We could make this dynamically sized,
but I'm not sure what the point is.
