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.

Add new 'link' subcommand 'add' and 'delete' to allow binding a soft-rdma
device to a netdev interface.
EG:
rdma link add rxe_eth0 type rxe netdev eth0
rdma link delete rxe_eth0

The port capability mask represents IBTA PortInfo specification,
but as it is written in description of kernel commit 2f944c0fbf58
("RDMA: Fix storage of PortInfo CapabilityMask in the kernel"),
the bit 26 was mistakenly overwritten.
The rdmatool followed it too and mislead users by presenting wrong
value. Since it never showed proper value, we update the whole
port_cap_mask to comply with IBTA and show real HW values.

According to the IBTA spec [1], the physical connected port is provided
for the QP in RTR-to-INIT stage performed by modify_qp(). It causes
to do not have port number for newly created QPs.
The following patch adds "-" sign to present absence of port, because
QPs are going to be associated with rdmatool link object, which needs
port number as an index.
