The citied commit broke the CLI output and printed ifindex/ifname
instead of dev/link.

[leonro@vm ~]$ rdma res show cq
ifindex 0 ifname rocep0s9 cqn 0 cqe 1023 users 2 poll-ctx WORKQUEUE adaptive-moderation on comm ib_core

With this new criteria, QPs have different PIDs will be bound to
different counters in auto mode. This can be used in combination with
other criteria like "type". Examples:
$ rdma statistic qp set link mlx5_2/1 auto pid on
$ rdma statistic qp set link mlx5_2/1 auto type,pid on
$ rdma statistic qp set link mlx5_2/1 auto off
$ rdma statistic qp show link mlx5_0 qp-type UD

Instead of doing open-coded solution to generate JSON and prints, let's
reuse existing infrastructure and APIs to do the same as ip/*.
Before this change:
if (rd->json_output)
jsonw_uint_field(rd->jw, "sm_lid", sm_lid);
else
pr_out("sm_lid %u ", sm_lid);
After this change:
print_uint(PRINT_ANY, "sm_lid", "sm_lid %u ", sm_lid);
All the print functions are converted to support color but for now the
type of color is COLOR_NONE. This is done as a preparation to addition
of color enable option. Such change will require rewrite of command line
arguments parser which is out-of-scope for this patch.

RDMA has weak connection between PIDs and HW objects, because
the latter tied to file descriptors for their lifetime management.
The outcome of such connection is that for the following scenario,
the returned PID will be 0 (not-valid):
1. Create FD and context
2. Share it with ephemeral child
3. Create any object and exit that child
This flow was revealed in testing environment and of course real users
are not running such scenario, because it makes no sense at all in RDMA
world.
Let's do two changes in the code to support such workflow anyway:
1. Remove need to provide PID/kernel name. Code already supports it,
just need to remove extra validation.
2. Ball-out in case PID is 0.

This enhancement allows printing rdma device-specific state, if provided
by the kernel. This is done in a generic manner, so rdma tool doesn't
need to know about the details of every type of rdma device.
Driver attributes for a rdma resource are in the form of <key,
[print_type], value> tuples, where the key is a string and the value can
be any supported driver attribute. The print_type attribute, if present,
provides a print format to use vs the standard print format for the type.
For example, the default print type for a PROVIDER_S32 value is "%d ",
but "0x%x " if the print_type of PRINT_TYPE_HEX is included inthe tuple.
Driver resources are only printed when the -dd flag is present.
If -p is present, then the output is formatted to not exceed 80 columns,
otherwise it is printed as a single row to be grep/awk friendly.
Example output:
# rdma resource show qp lqpn 1028 -dd -p
link cxgb4_0/- lqpn 1028 rqpn 0 type RC state RTS rq-psn 0 sq-psn 0 path-mig-state MIGRATED pid 0 comm [nvme_rdma]

2. Provide illegal port number (0 is illegal):
$ rdma res show qp link mlx5_4/0

4. Get QPs which have not assigned port yet:
link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib]
5. Limit to specific Local QPNs:
$ rdma res show qp link mlx5_4/1 lqpn 1-3,7
