Dmitry Yakunin 7bd9188581 ss: add checks for bc filter support
As noted by David Ahern, now if some bytecode filter is not supported
by running kernel printed error message is not clear. This patch is attempt to
detect such case and print correct message. This is done by providing checking
function for new filter types. As example check function for cgroup filter
is implemented. It sends correct lightweight request (idiag_states = 0)
with zero cgroup condition to the kernel and checks returned errno. If filter
is not supported EINVAL is returned. Result of checking is cached to
avoid extra checks if several same filters are specified.

This is a set of utilities for Linux networking.

How to compile this.
--------------------
1. libdbm

arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines.  Often this is in the db-devel package.

2. make

The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.

3. To make documentation, cd to doc/ directory , then
   look at start of Makefile and set correct values for
   PAGESIZE=a4		, ie: a4 , letter ...	(string)
   PAGESPERPAGE=2	, ie: 1 , 2 ...		(numeric)
   and make there. It assumes, that latex, dvips and psnup
   are in your path.

4. This package includes matching sanitized kernel headers because
   the build environment may not have up to date versions. See Makefile
   if you have special requirements and need to point at different
   kernel include files.
