Added httpd_squid_script_t
squid_conf_t can be a directory
Squid also needs additional ports to communicate with
dovecot and snmp try to read squid files. (Snuck in a couple of other
fixes for dovecot and snmp)

This brings up a problem to which I currently don't have a good
solution. Due to the encapsulation, the squid module doesn't actually
know how many types are created or their names when using
apache_content_template(), so httpd_squid_script_t can't be used here.

Yeah - there isn't really a good solution. You could argue that the
types are actually for the squid module (otherwise it would be an
interface rather than a template), but you still have the problem that a
change to the template could result in different types.
We should think about this for when interfaces are pushed into the
language.

Merged except for the apache template, plus:

The second interface is missing.

This one is missing too.

Ok here is an updated patch with the missing interfaces.
snmp is trying to execute sys_module, we are dontauditing
Switched from using nis_use_ypbind to nsswitch, since snmp is using nsswitch
Also sneaking in a fix for manage sendmail_log_t.
