Improve trace().

Turn on trace() with the TRACE macro and remove the ## token paste
preprocessor operator which is unnecessary here and causes these errors:

ps/common.h:176:26: error: pasting "(" and ""ps_argv[thisarg] is %s\n""
does no t give a valid preprocessing token
.

Send trace output to STDERR.

Tracing can be enabled by adding TRACE to CPPFLAGS as follows:

./configure CPPFLAGS="-DTRACE"
