+ switched from mmap based writing to simpler stdio based writing. Has
    a minor impact (0.5 microseconds) on microbenchmarks for asynchronous
    writes. Synchronous writes speed up from 30ms to 10ms on linux/ext4.
    Should be much more reliable on diverse platforms.
  + compaction errors now immediately put the database into a read-only
    mode (until it is re-opened). As a downside, a disk going out of
    space and then space being created will require a re-open to recover
    from, whereas previously that would happen automatically. On the
    plus side, many corruption possibilities go away.
  + force the DB to enter an error-state so that all future writes fail
    when a synchronous log write succeeds but the sync fails.
  + repair now regenerates sstables that exhibit problems
  + fix issue 218 - Use native memory barriers on OSX
  + fix issue 212 - QNX build is broken
  + fix build on iOS with xcode 5
  + make tests compile and pass on windows
- refreshed 0001-debian-ports.patch
  + moved OS_MACOSX hunk
