31ae2912f7 libnetlink: Rename rtnl_wilddump_* to rtnl_linkdump_*
Rename rtnl_wilddump_req_filter to rtnl_linkdump_req_filter,
rtnl_wilddump_request to rtnl_linkdump_req and
rtnl_wilddump_req_filter_fn to rtnl_linkdump_req_filter_fn.

In all cases drop the type argument which at this point is only
RTM_GETLINK and hardcode in the functions.

fe269b6e7c utils: Reimplement ll_idx_n2a() and introduce ll_idx_a2n()
Now all users of ll_idx_n2a() replaced with ll_index_to_name() we can
move it's functionality to ll_index_to_name() and implement index to
name conversion using snprintf() and "if%u".

Use %u specifier in "if%..." template consistently: network device
indexes are always greather than zero.

Also introduce ll_idx_n2a() conterpart: ll_idx_a2n() that is used
to translate name of the "if%u" form to index using sscanf().

4b9e917822 lib/ll_map: Choose size of new cache items at run-time
Instead of having a fixed buffer of 16 bytes for the interface name,
tailor size of new ll_cache entry using the interface name's actual
length. This also makes sure the following call to strcpy() is safe.

d17b136f7d Use C99 style initializers everywhere
This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).

Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.

The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.

d652ccbf81 netns: allow to dump and monitor nsid
Two commands are added:
 - ip netns list-id
 - ip monitor nsid

A cache is also added to remember the association between the iproute2 netns
name (from /var/run/netns/) and the nsid.
To avoid interfering with the rth socket, a new rtnl socket (rtnsh) is used to
get nsid (we may send rtnl request during listing on rth).

Example:
$ ip netns list-id
nsid 0 (iproute2 netns name: foo)
$ ip monitor nsid
Deleted nsid 0 (iproute2 netns name: foo)
nsid 16 (iproute2 netns name: bar)

cd70f3f522 libnetlink: remove unused junk callback
Both rtnl_talk and rtnl_dump had a callback for handling portions
of netlink message that do not match the correct pid or seq.
But this callback was never used by any part of iproute2 so remove
it.

ee7ba9875d iproute2: Add ll_index_to_addr function
After calling ll_init_map, all of the information stored in the link-layer map
can be retrieved by function calls (ll_index_to_*), except for the link-layer
address. This patch fills the gap by adding a ll_index_to_addr function.
Changes welcome.

linux/if.h into the directory with the local copies.
This caused troubles with outdated redefinitions from net/if.h
so I've removed the dependency on it.
