As discussed in this thread:
http://mail.python.org/pipermail/python-dev/2010-March/098500.html
The syslog module is using the C argv[0] as the program name, not the python sys.argv[0]. So, in most cases this means that unless you explicitly set a ident, you get "python" as the ident. Not entirely helpful.
This patch:
 - Makes openlog arguments keyword args.
 - Makes openlog ident argument optional.
 - If ident is not passed to ident, basename(sys.argv[0]) is used.
 - The first call to syslog.syslog() calls ident() with no options
 (if it hasn't previously been called).
 - Variously related documentation changes.
"make test" with this succeeds.
I think this is ready to go into the trunk, but would like a review. I'll check with the release maintainer about if this is appropriate for 2.7b.
