- remove clamav flavour in favour of enabling clamd support in
the main package.
- rearrange the Makefile slightly
the clamav flavour was using libclamav, which past experience shows
to not be a stable interface to the clamav virus scanner; dansguardian
also supports scanning via the clamd socket, this is now enabled
instead (by default since it doesn't add a required dependency).
note: those currently using the clamav flavour and upgrading will
need to adjust their configuration.
maintainer timeout. on ports@ for a few days, lightly tested here
but lacking test reports from real users.
