[DCCP]: enable debug messages also for static builds 

This patch
  * makes debugging (when configured) work both for static / module build
  * provides generic debugging macros for use in other DCCP / CCID modules
  * adds missing information about debug parameters to Kconfig
  * performs some code tidy-up

---help---
Only use this if you're hacking DCCP.
When compiling DCCP as a module, this debugging output can be toggled
by setting the parameter dccp_debug of the `dccp' module to 0 or 1.
Just say N.
