[NETFILTER]: xt_TOS: Change semantic of mask value
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.)

[NETNS]: Namespacing IPv4 fib rules.
The final trick for rules: place fib4_rules_ops into struct net and
modify initialization path for this.

[NETNS]: Show routing information from correct namespace (fib_trie.c)
This is the second part (for the CONFIG_IP_FIB_TRIE case) of the patch
#4, where we have created proc files in namespaces.
Now we can dump correct info in them.

[NETNS]: Add netns to nl_info structure.
nl_info is used to track the end-user destination of routing change
notification. This is a natural object to hold a namespace on. Place
it there and utilize the context in the appropriate places.

[NETNS]: Add netns parameter to inet_(dev_)add_type.
The patch extends the inet_addr_type and inet_dev_addr_type with the
network namespace pointer. That allows to access the different tables
relatively to the network namespace.
The modification of the signature function is reported in all the
callers of the inet_addr_type using the pointer to the well known
init_net.
