Dmitri Smirnov cdad04b051 Remove double buffering on RandomRead on Windows. 
Summary:
Remove double buffering on RandomRead on Windows.
  With more logic appear in file reader/write Read no longer
  obeys forwarding calls to Windows implementation.
  Previously direct_io (unbuffered) was only available on Windows
  but now is supported as generic.
  We remove intermediate buffering on Windows.
  Remove random_access_max_buffer_size option which was windows specific.
  Non-zero values for that opton introduced unnecessary lock contention.
  Remove Env::EnableReadAhead(), Env::ShouldForwardRawRequest() that are
  no longer necessary.
  Add aligned buffer reads for cases when requested reads exceed read ahead size.
Closes https://github.com/facebook/rocksdb/pull/2105
