This commit adds CIDR parsing and IP validate helper function to parse
single IP or range of IP with CIDR. (e.g. 198.18.0.0/15)
Validating the address should be preceded prior to the parsing.
Helpers will be used in prior to set target address in samples/pktgen.

Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread',
'pg_set'. proc_cmd is designed to check command result with grep the
"Result:", but this might fail since this string is only shown in
'pg_thread' and 'pg_set'.
This commit fixes this logic by grep-ing the "Result:" string only when
the command is not for 'pg_ctrl'.
For clarity of an execution flow, 'errexit' flag has been set.
To cleanup pktgen on exit, trap has been added for EXIT signal.

This commit adds port parsing and port validate helper function to parse
single or range of port(s) from a given string. (e.g. 1234, 443-444)
Helpers will be used in prior to set target port(s) in samples/pktgen.

1. given a device, get its NUMA belongings
2. given a device, get its queues' irq numbers.
3. given a NUMA node, get its cpu id list.

Preparing for removing existing samples/pktgen/ scripts, and
replacing these with easier to use samples.
This commit provides two helper shell files, that can
be "included" by shell source'ing. Namely "functions.sh"
and "parameters.sh".
The parameters.sh file support easy and consistant parameter
parsing across the sample scripts. Usage example is printed on
errors.
The functions.sh file provides, three new shell functions for
configuring the different components of pktgen: pg_ctrl(),
pg_thread() and pg_set(). A slightly improved version of the old
pgset() function is also provided for backwards compat.
The new functions correspond to pktgens different components.
* pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
* pg_thread() control the kernel threads and binding to devices
* pg_set() control setup of individual devices
These changes are borrowed from:
