osd/OSDMap: more efficient PGMapTemp

Use a flat_map with pointers into a buffer with the actual data.  For a
decoded mapping, we have just two allocations (one for flat_map and one
for the encoded buffer).

This can get slow if you make lots of incremental changes after the fact
since flat_map is not efficient for modifications at large sizes.  :/
