Removing the WRITEMAP test dropped this into the MDB_VL32 code path,
which was wrong.

a6ccef73ed ITS#8324 fix c4e31434c7 
Actually, there is no guarantee that Windows will map newly written
data, so we need VirtualAlloc even for non-WRITEMAP.

5db0b54ca1 Fixups for env_copy with large files 
wsize was being truncated to 32bits on Windows.
Only try to write 1GB at a time on Windows64;
larger writes fail with ERROR_WORKING_SET_QUOTA.

5eb25c5cb9 MDB_VL32 - fix for Win32 read-only envs 
We can't map with MEM_RESERVE because that requires write access
to the underlying file/section. Mapping with the default (MEM_COMMIT)
requires that we don't map past the end of the file.

3a2ac24f5b MDB_VL32 - track overflow pages too 
Otherwise they'll fill up the txn's pageref list when traversing
a DB with lots of overflow records.

6534b804a5 mdb_page_alloc(): Use original snapshot of freeDB. 
I can't help thinking this should be safer, and useful somewhere.

209b56fead ITS#8324 fix for WRITEMAP 
We called FlushViewOfFile with (map,mapsize) which worked fine
when we had allocated the entire map already. Now we have to make
sure to only flush as much as was actually written. Add a numpgs
argument to tell how much to flush in env_sync0().

1ba5adb2ec MDB_VL32 preparation 
Use 64 bit types consistently. This keeps database structures the
same size for MDB_VL32 and native 64 bit builds.

is only temporary and will be fixed by the time rebalance finishes.

c4e31434c7 ITS#8324 additional tweaks 
VirtualAlloc is only needed with WRITEMAP. Regular writes
already extend the mmap implictly.
