Comment:

 > Shouldn't the header include everything?
 I've taken out <log/macros.h> from main.cc as it is included in
 resolver_log.h.  The other two includes - logger_support.h and
 debug_levels.h - are only used by main.cc so I felt that they were better
 explicitly included in that file.

 it's probably matter of preference, so no big deal if you want it this
 way)
 They were direct translations from the original dlog() calls.  However,
 the ability to pass objects to the .arg() calls without the need to call
 methods to get the string representation is very convenient and does make
 the code clearer.  I've made the changes suggested (and in a couple of
 other places where there was a toText() call).
