Implement an option (-b) to execute RDMAtool commands
from supplied file. This follows the same model as
in use for ip and devlink tools, by expecting
every new command to be on new line.
These commands are expected to be without any -*
(e.g. -d, -j, e.t.c) global flags, which should be
called externally.

The global resource summary information. The object names, current utilization
and maximum numbers are received as is from the kernel.
$ rdma res

3: mlx5_2: pd 3 cq 5 qp 4

$ rdma res show mlx5_4

This patch adds general infrastructure to RDMAtool to handle various
filtering options needed for the downstream resource tracking patches.
The infrastructure is generic and stores filters in list of key<->value
entries. There are three types of filters:
1. Numeric - the values are intended to be digits combined with '-' to
mark range and ',' to mark multiple entries, e.g. pid 1-100,234,400-401
is perfectly legit filter to limit process ids.
2. String - the values are consist from strings and "," as a denominator.
3. Link - special case to allow '/' in string to provide link name, e.g.
link mlx4_1/2.

Device (dev) object represents struct ib_device to the user space.
Device properties:
* Device capabilities
* FW version to the device output
* node_guid and sys_image_guid
* node_type

RDMA devices are cross-functional devices from one side,
but very tailored for the specific markets from another.
Such diversity caused to spread of RDMA related configuration
across various tools, e.g. devlink, ip, ethtool, ib specific and
vendor specific solutions.
This patch adds ability to fill device and port information
by reading RDMA netlink.
