This commit adds an interface to get the statistics (64-bits) from
CAN interface. See more information from /usr/include/linux/if_link.h
where defines the struct rtnl_link_stats64.
Compare to the rtnl_link_stats, rtnl_link_stats64 was introduced
since linux kernel 2.6. After that the rtnl_link_stats is synchronous
with struct rtnl_link_stats64 by truncating each member from 64 bits
to 32 bits. Actually, the struct rtnl_link_stats is kept for
compatibility.

libsocketcan always retrieves link information from all interfaces
instead of only specified one. This commit fixes the issue by appending
an interface information to dump request netlink message.
See man 7 rtnetlink for detail description in section 'RTM_GETLINK'.

Because max is the index of the last element in array tb, max+1
elements need to be initialized.

This bug was detected by the clang warning:

Prior to this commit, do_get_nl_link assumed there would only be a single
reply for a dump request. On my system with multiple can interfaces, this
would cause only half of them to be listed in the dump reply. This change
checks for NLMSG_DONE dump terminator and stops receiving messages once
received.

When using libsocketcan on git://git.pengutronix.de/git/tools/libsocketcan.git,
I kind of missed a method to fetch the can device statistics.
This patch adds that functionality.
I think this is the proper library to put such function.

we now have can_set_bitrate and can_set_bitrate_samplepoint. The second is for
convenience for the developer. We tend to let the kernel use CIA recommnended
sample point value, which can_set_bitrate simply does
