of already closed handle.

Write decreases too, not just increases. Check for any size change
that was not requested by this process.

e1a676eb18 ITS#7713 cleanups 
'#ifdef MDB_DEVEL' -> '#if MDB_DEVEL'
Fix comments, use actual PAGEBASE macro as originally intended.
Actually enable 64K pages. Set MDB_DATA_VERSION for testing only.

6ed295b256 Fixes for loose pages 
mdb_txn_commit(child): Give loose pages to parent.
Use a pointer beyond the page header instead of mp_next, so
we will not need to save/restore mp_pgno. This avoids a crash
caused by references to mp_pgno.

68e6faad5c ITS#7713 handle 65536 byte page size 
Fix mp_lower/mp_upper to exclude PAGEHDRSZ, which means our
max mp_upper is now pagesize - PAGEHDRSZ and won't overflow.
Currently must define MDB_DEVEL to use. Will be default for
LMDB 1.0/OpenLDAP 2.5

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.

91d8ad1d3c Fix mdb_page_loose() vs. mdb_page_flush(). 
Do not overwrite loose pages' mp_pgno with mp_next.
mdb_page_flush() will use mp_pgno to rebuild dirty_list.

c73f087750 Trap signals 
Try to exit cleanly to avoid leaving stale readers. Not
a critical issue since mdb_reader_check can take care of
them, but still cleaner.

Just use srand/rand, we don't care about the quality
of the random numbers, we just want some data.
