Make the dss log facility C89 conform.

Variadic macros were introduced in C99, so they are not supported on
ANSI C compilers. Since currently all DSS_*_LOG macros are variadic,
we need a replacement for these. Moreover, since not all compilers
support __func__ or an equivalent, we need to check for this feature
as well and provide a workaround if necessary.

This patch introduces the new public function dss_log_set_params()
which saves the given log level, filename, line number and the
function name in global variables. The DSS_*_LOG macros are changed
to receive a single argument only, which is the usual variadic list,
enclosed in additional parentheses.

The new DSS_*_LOG macros first set the log parameters by calling
dss_log_set_params(), then call dss_log() with the variadic list as
the argument. dss_log() is patched to print the function name only
if __func__ is supported and fall back to file name and the line
number otherwise.

All DSS_*_LOG() calls are changed to the new syntax.
