[Patch 0/3] dccp: Lockless use of CCID blocks

[Gerrit Renker <gerrit@erg.abdn.ac.uk>]

Hi Dave,

please find attached an updated and tested revision of the earlier 
patch set to enable lockless use of CCID plugins within DCCP.

It combines the initial patch by Arnaldo with further work, following
discussions on this mailing list.

All patches have been compile individually (sparse enabled) and have
been verified to work.

Wishing a good new year
Gerrit


Changes relative to earlier revision:
-------------------------------------
 * incorporated Arnaldo's feedback regarding the deletion of jump labels
 * and the renaming of the register/unregister functions (for want of a
   better word, 'activate' has been used here);
 * added un-registration function to allow module unloading;
 * removed now obsolute module references from the CCIDs (ccid_owner);
 * updated Kconfig menu to reflect all the new changes.


List of patches:
----------------
Patch #1: Integrates CCID plugins with dccp.ko main module.
Patch #2: Cleans up the old interface.
Patch #3: Integrates the TFRC library, a dependency of CCID-3.

CCID-4 has also been updated and likewise been tested - negotiation,
as well as a longer test involving audio streaming.
