netfilter: ipset: bitmap:ip set type support

The module implements the bitmap:ip set type in two flavours, without
and with timeout support. In this kind of set one can store IPv4
addresses (or network addresses) from a given range.

In order not to waste memory, the timeout version does not rely on
the kernel timer for every element to be timed out but on garbage
collection. All set types use this mechanism.

netfilter: ipset: bitmap:ip,mac type support

The module implements the bitmap:ip,mac set type in two flavours,
without and with timeout support. In this kind of set one can store
IPv4 address and (source) MAC address pairs. The type supports elements
added without the MAC part filled out: when the first matching from kernel
happens, the MAC part is automatically filled out. The timing out of the
elements stars when an element is complete in the IP,MAC pair.

netfilter: ipset; bitmap:port set type support

The module implements the bitmap:port type in two flavours, without
and with timeout support to store TCP/UDP ports from a range.

netfilter: ipset: hash:ip,port set type support

The module implements the hash:ip,port type support in four flavours:
for IPv4 and IPv6, both without and with timeout support. The elements
are two dimensional: IPv4/IPv6 address and protocol/port pairs. The port
is interpeted for TCP, UPD, ICMP and ICMPv6 (at the latters as type/code
of course).

netfilter: ipset: hash:ip,port,ip set type support

The module implements the hash:ip,port,ip type support in four flavours:
for IPv4 and IPv6, both without and with timeout support. The elements
are three dimensional: IPv4/IPv6 address, protocol/port and IPv4/IPv6
address triples.

netfilter: ipset: hash:ip,port,net set type support

The module implements the hash:ip,port,net type support in four flavours:
for IPv4 and IPv6, both without and with timeout support. The elements
are three dimensional: IPv4/IPv6 address, protocol/port and IPv4/IPv6
network address/prefix triples. The different prefixes are searched/matched
from the longest prefix to the shortes one (most specific to least).
In other words the processing time linearly grows with the number of
different prefixes in the set.
