Bug Description

1. As per RFC-2616 14.35.1 when a byte range is submitted in a GET the "last-byte-pos value gives the byte-offset of the last byte in the range". Eucalyptus instead returns one byte less than expected. It seems to me that the issue is in FileSystemStorageManager#sendObject when initializing the ChunkedDataFile (or the compressed one).

2. Still as per the same reference, the server SHOULD return a response with a status of 206 (Partial Content) instead of 200 (OK).

Also per the same RFC, specifying an incomplete range like:
  Range: bytes=567889-
should be accepted.

Currently it returns a 500 'Internal error' which is reflected in logs by:
14:59:12 [WalrusRESTBinding:New I/O server worker #1-4] ERROR java.lang.ArrayIndexOutOfBoundsException: 1
