[lwip-users] typo in src/core/pbuf.c:770

[Mike Tesch]

%q should be %p

also, to get rid of a bunch of compiler warnings I added
parens around (debug) in the definition of DEBUGF():

#define DEBUGF(debug, x) \
do { \
 if (((debug) & DBG_ON) && \
     ((debug) & DBG_TYPES_ON) && \
     (((debug) & DBG_MASK_LEVEL) >= DBG_MIN_LEVEL)) { \
   LWIP_PLATFORM_DIAG(x); \
   if ((debug) & DBG_HALT) \
     while(1); \
 } \
} while(0)
