Some applications doesn't have the pcap link flag
when shared libraries are enabled.
Indeed in such case, pcap PMD must not be linked but pcap library should.
Actually -lpcap is always needed if pcap PMD is used,
and -lrte_pmd_pcap must be set only with static PMD library.
So the flags -lrte_pmd_pcap and -lpcap are enabled separately.
Workarounds in test-pmd/ and test-pipeline/ can be removed.

No need to test some build option multiple times in a Makefile.
Besides, such option is needed by the associated app, so move it at the
top of the Makefile.

This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].

Add a new specific packet processing engine in the "testpmd" application that
only replies to ARP requests and to ICMP echo requests.
For this purpose, a new "icmpecho" forwarding mode is provided that can be
dynamically selected with the following testpmd command:
set fwd icmpecho
before starting the receipt of packets on the selected ports.
Then, the "icmpecho" engine performs the following actions on all received
packets:
- replies to a received ARP request by sending back on the RX port a ARP
reply with a "sender hardware address" field containing the MAC address
of the RX port,
- replies to a ICMP echo request by sending back on the RX port a ICMP echo
reply, swapping the IP source and the IP destination address in the IP
header,
- otherwise, simply drops the received packet.
When replying to a received packet that was encapsulated into a VLAN tunnel,
the reply is sent back with the same VLAN identifier.
By default, the testpmd configures VLAN header stripping RX option on each
port.
This option is not managed by the icmpecho engine which won't detect
packets that were encapsulated into a VLAN.
To address this issue, the VLAN header stripping option must be previously
switched off with the following testpmd command:
vlan set strip off
When the "verbose" mode has been set with the testpmd command
"set verbose 1", the "icmpecho" engine displays informations about each
received packet.
The "icmpecho" forwarding engine can also be used to simply check port
connectivity at the hardware level (check that cables are well-plugged)
and at the software level (receipt of VLAN packets, for instance).

This commit adds a multi-flow traffic generator forwarding engine. In effect,
this forwarding mode functions very similar to the txonly mode, with the
difference that it generates multiple L4 flows.

This commit adds a new forwarding mode, in which the source and destination
MAC addresses of packets are swapped before forwarding according to the
port-topology in effect. This has been designed for operation primarily with
--port-topology=loopback.

This reverts commits
a0cdfcf9 (use pcap-config to guess compilation flags),
ef5b2363 (fix build with empty LIBPCAP_CFLAGS) and
60191b89 (fix build when pcap_sendpacket is unavailable).
These patches are creating more problems than solving the initial one
(which was a build error with too old pcap libraries).
Since old pcap libraries are not that common, just revert them.

This adds a new forwarding mode to testpmd, whereby it will forward
packets, but on a transmit failure, it will wait a small amount of time
before retrying the transmit again. This mode can be useful in some
cases to set a zero-packet loss rate at the cost of overall throughput,
especially in cases where TX ring size/buffering is constrained, such as
with virtio.
