Werner Koch 5857491a2a
core: Simplify the trace maros by using variadics.
* src/debug.h (TRACE_BEG, TRACE_LOG, TRACE_SUC): Use variadic macros
and remove the TRACE_BEG1 et al.  Change all users to always pass a
format string.
(TRACE): Ditto.
* src/debug.c (_gpgme_debugf): New.
* configure.ac <GCC>: Add -Wno-format-zero-length.
--

This makes it easier for use to enable format checks.  The zero-length
format is required to allow for an empty format due to the comman
problematic of __VA_ARGS__.
