validate_host

Validate the given host for this site.

Check that the host looks valid and matches a host or host pattern in the given list of allowed_hosts. Any pattern beginning with a period matches a domain and all its subdomains (e.g. .example.com matches example.com and any subdomain), * matches anything, and anything else must match exactly.

Note: This function assumes that the given host is lowercased and has already had the port, if any, stripped off.

Return True for a valid host, False otherwise.
