Changes since V1:
 * Implemented fixes suggested by Moritz Barsnick (if/else whitespace)
 * Strict checking on overread of the IP packet data
 * Fixed checking the size of the IP packet header size (6 vs 8)

Changes since V2:
 * Correct the header size check found by Paul B Mahol

This patch series implement the previously unknown opcodes 0x06, 0x0E,
and 0x010 for Interplay MVE movies.

With this series every MVE sample[0] plays correctly, but I have some
doubts as to the implementation of the extra two AVFrames necessary for
format 0x10. If someone has a better idea on how to achieve this I'll
happily rework it as necessary.

I've tried to split up the patchset logically, I hope this makes sense.

I'm working with Multimedia Mike to get detailed information on the frame
formats added to multimedia.cx

If preferred the patchset is also available on github[1]

[PATCH v2 1/5] Interplay MVE: Implement MVE SEND_BUFFER operation
 This patch implements a feature that wasn't used for 0x11 formatted movies.
 See the commit message for details.

[PATCH v2 2/5] Interplay MVE: Refactor IP packet format
 This patch changes the IP packet format for interplaymovie. The reason for
 this is that frame format 0x10 requires an extra stream of data for a total
 of three to work correctly. This generalizes that for all frame formats.

[PATCH v2 3/5] Interplay MVE: Implement frame format 0x06
[PATCH v2 4/5] Interplay MVE: Implement frame format 0x10
[PATCH v2 5/5] Interplay MVE: Changelog entry for changes
