Improve batch and dump times by caching link lookups
ip route uses ll_name_to_index and ll_index_to_name to convert between
device names and indices. At the moment both use for the ioctl based glibc
functions if_nametoindex and if_indextoname and does not cache the result.
When using a batch file or dumping large number of routes this means the
same device lookups can be done repeatedly adding unnecessary overhead
(socket + ioctl + close for each device lookup).
Add a new function, ll_link_get, to send a netlink based RTM_GETLINK. If
successful, cache the result in idx_head and name_head so future lookups
can re-use the entry. Update ll_name_to_index and ll_index_to_name to use
ll_link_get and only fallback to the glibc functions if it fails.
With this change the time to install 720,022 routes with 2 ecmp nexthops
where the nexthop device is given is reduced from 31.4 seconds to 19.2
seconds. A dump of those routes drops from 13.3 to 2.8 seconds.

ss: Render buffer to output every time a number of chunks are allocated
Eric reported that, with 10 million sockets, ss -emoi (about 1000 bytes
output per socket) can easily lead to OOM (buffer would grow to 10GB of
memory).
Limit the maximum size of the buffer to five chunks, 1M each. Render and
flush buffers whenever we reach that.
This might make the resulting blocks slightly unaligned between them, with
occasional loss of readability on lines occurring every 5k to 50k sockets
approximately. Something like (from ss -tu):
However, I don't actually expect any human user to scroll through that
amount of sockets, so readability should be preserved when it matters.
The bulk of the diffstat comes from moving field_next() around, as we now
call render() from it. Functionally, this is implemented by six lines of
code, most of them in field_next().

ipneigh: print dst for AF_BRIDGE
In case a neighbour message is of family AF_BRIDE the NDA_DST attribute
was not printed so far. With this patch the family is evaluated to pass
the correct family to format_host_rta.

libnetlink: linkdump_req is done for AF_BRIDGE as well

bridge: fdb: Fix filtering with strict checking disabled
Older kernels expect an ifinfomsg struct as the ancillary header, and
after kernel commit bd961c9bc664 ("rtnetlink: fix rtnl_fdb_dump() for ndmsg
header") can handle either ifinfomsg or ndmsg. Strict data checking only
allows ndmsg.
Use the new RTNL_HANDLE_F_STRICT_CHK flag to know which header to send.

rdma: Fix incorrectly handled NLA validation
mnl_attr_type_valid() receives maximum attribute type, which means that
we were supposed to supply the latest valid netlink attribute and not
the number of attributes. Such coding mistake caused to failures while
NLA attributes were extended.

A recent change reduced max line length from 4096 to 2048 bytes,

Switch to getline() and do not worry about future kernel changes.

bridge: fdb: Use 'struct ndmsg' for FDB dumping
Since commit aea41afcfd6d ("ip bridge: Set NETLINK_GET_STRICT_CHK on
socket") iproute2 uses strict checking on kernels that support it. This
causes FDB dumping to fail [1], as iproute2 uses 'struct ifinfomsg'
whereas the kernel expects 'struct ndmsg'.
Note that with this change iproute2 continues to work on old kernels
that do not support strict checking, but contain the fix introduced in
kernel commit bd961c9bc664 ("rtnetlink: fix rtnl_fdb_dump() for ndmsg
header").

addition, add a new ipaddr_link_get to do a single RTM_GETLINK request
