c3375d0501 Fix MDP client packet receive bug on OSX 
Was failing because recvmsg(2) on OSX does not nul terminate the
pathname of local (AF_UNIX) sockets in the returned sockaddr buffer.
Zerofilling the buffer before calling recvmsg() does the trick.

In the process, improved debug and error logging, replacing
recvwithttl() with recv_message() and recv_message_frag().  The
mdp_net.c source file was retired.

7d9a5faa4e Move if(config.debug.xxx) tests into DEBUGF() 
Original DEBUG() and DEBUGF() macros renamed to _DEBUG() and _DEBUGF()
New DEBUG() and DEBUGF() macros, first argument is flagname
New DEBUGF2(foo, bar, ...) macro does if(config.debug.foo||config.debug.bar) test
Replace almost all config.debug.xxx references to IF_DEBUG(xxx)

53c1b1c04c Filesystem Heirarchy Standard (FHS) paths 
If no instance directory specified, then use paths like
/etc/serval/serval.conf
/var/cache/serval
/var/log/serval
/var/run/serval
etc. for files, instead of all in a single directory.

Log all directory creation as INFO messages.

Interpretation of log.file.directory_path has changed slightly.

Updated servald configuration tech doc.

30b2059608 Fix -Wunused-parameter warnings 
New UNUSED(param) macro suppresses the warning for a specific parameter

parameter in a DEBUGF() or assert() statement to document the intent.
