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__.

available.

This is a best effort feature to not output plaintext after a
decryption failure (e.g. due to no or broken authenticated
encryption).  It always work when using a memory object and reading it
after the decryption but it can't work reliable when the user is
reading from the data object while the decryption process is still
running.

This is quite a large change because the data objects and the context
objects are allowed to be owned by different threads.  Thus a
synchronization is needed and we do this with a global table of all
data objects to which the context objects can do soft-linking via a
unique data object serial number.

51fd6d8292 Use gpg_error_from_syserror instead of directly accessing errno.
--

Also fixed a couple of minor thing; e.g. save the error before calling
cleanup functions.  Do not save the errno if only free is called
in between.
