Partially revert 47f6aec6
Was using RANGE_FIRST/RANGE_LAST on an IDL known to *not* be a range.

Measured perf cost of meminit was 7% worst case on an Intel Core2
system. YMMV.

Silence warnings, fix broken MinGW64 definitions, etc.

Init malloc'd memory by default, use #MDB_NOMEMINIT to disable.
Bump version to 0.9.10

Initialize unused portions of DB pages, for security or to silence
checkers like Purify and Valgrind. Like BDB configure --enable-umrw.

A node may need room for [key, subpage with 2 items] = 3 keys.

Use DB page size = min(32k, OS pagesize).  Previous limit was 8k
(MDB_MINKEYS*MDB_PAGESIZE).

Handle DB pagesize < OS pagesize. That's an I/O pessimization,
but transactions remain atomic: Only writing the MDB_meta must
be atomic, and it fits in one OS page.

Don't truncate desired subpage size: Asssign it to a size_t
(mv_size), not an uint16_t (mp_upper).

Skip cursors that aren't as deep as current cursor

Closing a connection can abandon its ops without going thru the threadpool,
so make sure to lock the si_ops_mutex before walking the list.
