     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().

Do env_sync() and commit() survive the test program from ITS#7886?
It creates a datafile which ends before mm_last_pg+1.
