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.

e3b6c359a9 Use robust mutexes by default
Making it optional on pthreads just complicates things;
they're always robust on other implementations

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.
