Define the extended_socket_class policy capability used to enable
the use of separate socket security classes for all network address
families rather than the generic socket class. This also enables
separate security classes for ICMP and SCTP sockets, which were previously
mapped to the rawip_socket class.
The legacy redhat1 policy capability that was only ever used in testing
within Fedora for ptrace_child is reclaimed for this purpose; as far as
I can tell, this policy capability is not enabled in any supported distro
policy.

Currently the packet class in SELinux is not checked if there are no
SECMARK rules in the security or mangle netfilter tables. Similarly, the
peer class is not checked if there is no NetLabel or labeled IPSEC. Some
systems prefer that these classes are always checked, for example, to
protect the system should the netfilter rules fail to load or if the
nefilter rules were maliciously flushed.
Add the always_check_network policy capability which, when enabled, treats
these mechanisms as enabled, even if there are no labeling rules.
