(puremodule.c): New module which exports the Purify and Quantify C API
to Python.  Minimal documentation is included in comments at the top
of the file, and in the Misc/PURIFY.README file.  Note that this
module must be statically linked since Pure doesn't provide shared
stubs libraries.

(Setup.in): Added commented template for pure module

(syslogmodule.c): ins() function wasn't declared static.
