The restrack code has separate .c, so move callbacks initialization to
that file to improve code locality.

For debugging purpose it will be easier to understand if prefetch works
okay if it has its own counter. Introduce ODP prefetch counter and count
per MR the total number of prefetched pages.
In addition remove comment which is not relevant anymore and anyway not in
the correct place.

In order to avoid double multiplexing of the resource when it is a MR, add
a dedicated callback function.

Add RDMA nldev netlink interface for dumping MR statistics information.
Output example:
$ ./ibv_rc_pingpong -o -P -s 500000000
local address: LID 0x0001, QPN 0x00008a, PSN 0xf81096, GID ::
$ rdma stat show mr
dev mlx5_0 mrn 2 page_faults 122071 page_invalidations 0

Provide an ODP explicit/implicit type as part of 'rdma -dd resource show
mr' dump.
For example:
$ rdma -dd resource show mr
dev mlx5_0 mrn 1 rkey 0xa99a lkey 0xa99a mrlen 50000000
pdn 9 pid 7372 comm ibv_rc_pingpong drv_odp explicit
For non-ODP MRs, we won't print "drv_odp ..." at all.
