Initial set of changes for MP4 DTCP support
Tweaked the MP4 DTCP support to calculate the encrypted size using the entire MP4 serialized response

The DTCP response length is now calculated using the MP4 response size - not
 just the section of content data taken from the source resource.

Changed the logic to declare its own local range array before calling
 calculate_dtcp_encrypted_length().

Found/fixed a bug in the TimeSeekRange response when protection is not
 enabled. It was passing end_point.byte_offset-1 instead of
 end_point.byte_offset. The byte offsets from the MP4 AccessPoints are
 non-inclusive.

Testing is pending.
