     Add a netlink attribute INET_DIAG_SECCTX

     Add a new netlink attribute INET_DIAG_SECCTX to dump the security
     context of TCP sockets.

     The element sk_security of struct sock represents the socket
     security context ID, which is inherited from the parent process
     when the socket is created.

     but when SELinux type_transition rule is applied to socket, or
     application sets /proc/xxx/attr/createsock, the socket security
     context would be different from the creating process. For these
     conditions, the "netstat -Z" would return wrong value, since
     "netstat -Z" only returns the process security context as socket
     process security.


The application to verify the netlink new attribute.

See attached file

test:
--------
1. Enable SELinux when compile and startup .
	root@qemu-host:/root>  ./printsocketsec
	 inode:7141 system_u:system_r:rpcbind_t:s0
	 inode:7136 system_u:system_r:rpcbind_t:s0
	 inode:7604 system_u:system_r:initrc_t:s0
	 inode:7227 system_u:system_r:rpcd_t:s0
	 inode:7471 system_u:system_r:sshd_t:s0-s0:c0.c1023
	 inode:7469 system_u:system_r:sshd_t:s0-s0:c0.c1023
	 inode:7552 system_u:system_r:sendmail_t:s0
	 inode:7348 system_u:system_r:initrc_t:s0
	 inode:7553 system_u:system_r:sendmail_t:s0
	root@qemu-host:/root>

2. Disable SELinux when startup.
	root@qemu-host:/root>  ./printsocketsec

	inode:2942
	inode:2861
	inode:3256
	inode:3156

	inode:3060
