This patch changes the behavior of xt_TOS v1 so that the mask value
the user supplies means "zero out these bits" rather than "keep these
bits". This is more easy on the user, as (I would assume) people keep
more bits than zeroing, so, an example:
Action: Set bit 0x01.
before (&): iptables -j TOS --set-tos 0x01/0xFE
after (&~): iptables -j TOS --set-tos 0x01/0x01
This is not too "tragic" with xt_TOS, but where larger fields are used
(e.g. proposed xt_MARK v2), `--set-xmar 0x01/0x01` vs. `--set-xmark
0x01/0xFFFFFFFE` really makes a difference. Other target(!) modules,
such as xt_TPROXY also use &~ rather than &, so let's get to a common
ground.
(Since xt_TOS has not yet left the development tree en direction to
mainline, the semantic can be changed as proposed without breaking
iptables.)

Most of the netfilter modules are not considered experimental anymore,
the only ones I want to keep marked as EXPERIMENTAL are:
- TCPOPTSTRIP target, which is brand new.
- SANE helper, which is quite new.
- CLUSTERIP target, which I believe hasn't had much testing despite
being in the kernel for quite a long time.
- SCTP match and conntrack protocol, which are a mess and need to
be reviewed and cleaned up before I would trust them.

Show number of entries in trie, the size field was being set but never used,
but it only counted leaves, not all entries. Refactor the two cases in

inet_confirm_addr can be called with NULL in_dev from arp_ignore iff

arp_ignore has two arguments: dev & in_dev. dev is used for
inet_confirm_addr calling only.
inet_confirm_addr, in turn, either gets in_dev from the device passed
or iterates over all network devices if the device passed is NULL. It
seems logical to directly pass in_dev into inet_confirm_addr.
