6d63afb1d9 ITS#8311 fix page_split from update_key 
Check for top of stack. Usually the cursor only has height 1 when
calling page_split, but not always.

0c777dfc99 ITS#8300 fix rebalance after node_move 
ITS#8258, ITS#7829 fixes checked parent index to see if we were moving
from a left neighbor. Should have just checked to see if current index
was 0, meaning we added on the left. (Parent index may not tell us
anything meaningful after a nested rebalance.)

3e6ac6ef6b For ITS#7789: Ensure mapsize >= pages in use. 
Check new mapsizes against mm_last_pg.  Move
mdb_env_init_meta0() so it can set mm_last_pg earlier.

4008e5e583 Partially revert ada2630699 
Of course, MacOSX only has posix_memalign, and only in recent versions.
(Older versions could use valloc instead. That precludes ever changing
the LMDB pagesize to be different from the OS pagesize.) Not all that
crucial since it only affects mdb_env_copyfd1.

f3573a7383 Windows compat 
We mainly use Win32 functions, so cannot just use C-runtime strerror
to return error messages. We have to use Win32-specific messages.
Unfortunately, we document the API to return C-runtime error codes,
so we can't just switch to all Win32 error codes.
