[Swan-dev] DBG_* cleanout

[Andrew Cagney]

I'm planning on flushing out all these redundant macros:

-#define DBG_RAW        DBG_BASE
-#define DBG_PARSING    DBG_BASE
-#define DBG_EMITTING    DBG_BASE
-#define DBG_CONTROL    DBG_BASE
-#define DBG_LIFECYCLE    DBG_BASE
-#define DBG_KERNEL    DBG_BASE
-#define DBG_DNS        DBG_BASE
-#define DBG_OPPO    DBG_BASE
-#define DBG_CONTROLMORE    DBG_BASE
-#define DBG_NATT    DBG_BASE
-#define DBG_X509    DBG_BASE
-#define DBG_DPD        DBG_BASE
-#define DBG_XAUTH    DBG_BASE
-#define DBG_RETRANSMITS    DBG_BASE
-#define DBG_OPPOINFO    DBG_BASE
-#define DBG_PROPOSAL_PARSER    DBG_TMI

and where possible, reducing:
      DBG(DBG_<above>, DBG_log(...))
to just
      dbg(...)
