Gerrit Renker e28fe59f9c dccp ccid-2: Update code for the Ack Vector input/registration routine
This patch uupdates the code which registers new packets as received, using the
new circular buffer interface. It contributes a new algorithm which 
	* supports both tail/head pointers and buffer wrap-around and
	* deals with overflow (head/tail move in lock-step).

The updated code is also partioned differently, into
	1. dealing with the empty buffer,
	2. adding new packets into non-empty buffer,
	3. reserving space when encountering a `hole' in the sequence space,
	4. updating old state and deciding when old state is irrelevant.

Protection against large burst losses: With regard to (3), it is too costly to
reserve space when there are large bursts of losses. When bursts get too large,
the code does no longer reserve space and just fills in cells normally. This
measure reduces space consumption by a factor of 63.

The code reuses in part the previous implementation by Arnaldo de Melo.
