b3e144a7df des: add possibility to calculate DES-CBC-MAC with small buffer 
This patch adds the possibility to calculate the DES-CBC-MAC of a
source buffer (i.e. the last block of the buffer encrypted in CBC
mode) without having to allocate a destination buffer that is as
long as the complete source buffer, but instead only 8 bytes
for the MAC.

3ffe32eb96 rtmp: Don't blindly skip the 4 trailer bytes from the FLV packets 
If not enough bytes are available, keep track of them and skip
them on next call.

In practice, if these trailer bytes are written in a separate
call, there is no other data written in this call, making it
fall into the "FLV packet too small" case currently - working,
but not as intended.

This patch makes the code more robust, handling all cases
except for having the FLV packet header split over multiple
write calls.

a14c784210 rtmp: Handle FLV packets written in more than one write call 
If the FLV packet is larger than the AVIO buffer, a partial
FLV packet will be flushed to the RTMP protocol.

This commit handles the most common cases of FLV packets
being written in more than one call.
