5f6fa8c042 Remember if last cursor op was a delete 
If so, don't advance cursor on next NEXT. Also, init xcursor
on the next GET_CURRENT.

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.

2a28686e4f ITS#7672 fix mdb_dbi_flags

try to fake out the dirty list.

7b1db13050 Less aggressive page_spill 
spilling all possible pages is a waste because the majority will be
needed again. Just do 1/8th of the dirty list instead.

76f0a02485 ITS#7664 better fix 
For RDONLY, don't get lockfile until we know datafile exists.
Also, don't try to create a new datafile for me_mfd if someone
deleted it after we got me_fd.

5a5d33ff33 Fix obscure MDB_MULTIPLE bug 
If a key has a single existing value, and then a put (MDB_MULTIPLE)
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.

9c49ef1d71 Avoid compiling debug args with C90 compilers. 
Use double DPRINTF() parenthesis, so varargs macros are not needed.
Parenthesize MDB_DEBUG, in case the user defines it as foo || bar.

5645812f41 mdb_txn_commit(): Always commit if MDB_TXN_SPILLS. 
Checking dirty_list was insufficient after a spill
with no named databases and no positioned cursors.

38b11b1de1 mdb_cursorpages_mark: Mark current txn and no more. 
Ignore parent txn cursors since it is the current txn's dirty_list
which will be flushed. But check the current txn also when clearing,
since cursors can have pages which are dirty in a parent.

Check !mc_xcursor instead of !MDB_DUPSORT.  Equivalent for valid
data, but a bit safer if the sub-DB flags are corrupt.

2bd5d8102e Fix mdb_ovpage_free() vs. spill. 
Ensure me_pghead has room before removing from spill/dirty list.
Don't return pages to me_pghead in nested txns, use mt_free_pgs.

c3547e81f3 Fix page spilling when MDB_WRITEMAP.

d66739f947 MDB_LOCK_VERSION -> MDB_LOCK_FORMAT. 
Pid locking needs a different lockfile-version: MDB_env's with and
without pid locking must not coexist, they can sabotage each other.
Store MDB_LOCK_FORMAT = (version | "use locking" flag) instead.

1878213092 Fix mdb_reader_pid(). 
Treat unexpected errors as "don't know".  Invert Pidcheck return
value, so nonzero including error codes = "the process may exist".

On Windows: Catch exited but still existing processes.  Handle
undefined PROCESS_QUERY_LIMITED_INFORMATION.
On Unix: don't trust F_GETLK error to leave the input alone,
the fcntl() doc seems unclear.
