Marc Gilleron 89750a20f8 Made file streams thread-safe (but still won't be used in more than one thread)
- Added a global file locker so threads can synchronize when accessing files
- Added mutexes to serialize access to file streams (i.e to call in series)
- VoxelStream API now expects implementations to be thread-safe
- Did some logic/data separation in RegionFile in case we need an
  in-memory implementation, however I might just use SQLite in the
  future instead
