When using dumpcap in container environment or with multiple
DPDK processes, it is useful to be able to specify file prefix.
This version only accepts the long format option used by
other commands. If no prefix is specified then the default
is used.

The change to do argument process before EAL init broke
the support of select-interface option. Fix by setting flag
and doing select-interface later.

When dumpcap is run with a longer path name such as when
testing, the file prefix would be computed incorrectly.
Also, print out the resulting filename which is similar to
what wireshark program does.

At end of program there is call to rte_free() which is passing
a bogus value. There is no "bpf_filter" defined in this application;
it ends up being a text address inside pcap library.

Currently dumpcap tries to initialize dpdk before parsing command line
arguments, this makes it impossible to check version or help without
having the primary process running already.

If the rte_eth_promiscuous_enable() fails, then log the error
and continue.

The RTE_PORT_PCAP variable is used to signal libpcap availability,
though its name seems to refer to pcap support in the port library.
Prefer a generic name and add explicit link dependencies where needed.

rte_bpf_convert() implementation depends on libpcap.
Right now it is defined only when this library is installed and
RTE_PORT_PCAP is defined.
Fix that by providing for such case stub rte_bpf_convert()
implementation that will always return an error.
To draw user attention, if proper implementation is disabled,
warning will be thrown at meson configure stage.
Also move stub for another function (rte_bpf_elf_load) into
the same place (bpf_stub.c).

This is a new packet capture application to replace existing pdump.
The new application works like Wireshark dumpcap program and supports
the pdump API features.
It is not complete yet some features such as filtering are not implemented.
