Clean up debugging code #ifdefs (Eduardo Habkost)

Browse source 
Use macros to avoid #ifdefs on debugging code.

This patch doesn't try to merge logging macros from different files,
but just unify the debugging code #ifdefs onto a macro on each file. A
further cleanup can unify the debugging macros on a common header, later
