It would be useful for userspace to query the size of an ipset hash,
however, this data is not exposed to userspace outside of counting the
number of member entries. This patch uses the attribute
IPSET_ATTR_ELEMENTS to indicate the size in the the header that is
exported to userspace. This field is then printed by the userspace
tool for hashes.
Because it is only meaningful for hashes to report their size, the
output is conditional on the set type. To do this checking the
MATCH_TYPENAME macro was moved to utils.h.
The bulk of this patch changes the expected test suite to account for
the change in output.

Introduce packet mark mask for hash:ip,mark data type. This allows to
set mark bit filter for the ip set.

Introduce packet mark support with new ip,mark hash set. This includes
userspace and kernelspace code, hash:ip,mark set tests and man page
updates.
The intended use of ip,mark set is similar to the ip:port type, but for
protocols which don't use a predictable port number. Instead of port
number it matches a firewall mark determined by a layer 7 filtering
program like opendpi.
As well as allowing or blocking traffic it will also be used for
accounting packets and bytes sent for each protocol.
