Run tests in a forked process with a set of pipes to communicate
keep-alives and overall result. This allows us to detect when e.g.
vpp dies mid-API call causing the test to hang waiting for response
(which will never come since vpp died).
Support setting a (per test case) TIMEOUT make test option to set timeout,
with a default timeout of 120 seconds.
Example - fail the test suite if any test-case fails to finish within
300s:
make TIMEOUT=300 test

Add code which checks if vpp doesn't crash/exit immediately after
startup to aid debugging stuff like mistyped graph node name or so.
Refuse to run tests if the vpp is unable to start, complain loudly
and print vpp's stderr at critical log level if this happens to make
spotting these problems in jenkins easy.

- single-hop BFD: attach a delegate to the appropriate adjacency
- multi-hop BFD [not supported yet]: attach a delegate to the FIB entry.
adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it.
For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).

Implement plumbing to allow decorating tests as extended, e.g.:
@unittest.skipUnless(running_extended_tests(), "part of extended tests")
both methods and classes can be decorated this way.
Change make test and make test-debug to run only non-extended tests.
Introduce make test-all and make test-all-debug to run the full suite.
Run full suite as part of make verify.
Decorate most BFD tests as extended.

Under stress, it's possible to hit a race condition, when the packet
header is fully written to pcap, but not all packet data - yet.
Scapy is stupid enough to:
1. not detect and report this error, truncating the packet instead
2. continue munching more data from wrong offset
The work around is to scan the file ahead, parse the packet header,
figure out how much data we need, wait for the file to be big
enough, then restore the file position back to where it was
and finally let scapy parse the packet.

Perform accounting of expected packets based on created packet infos.
Use this accounting info to automatically expect (and verify) the
correct number of packets to be captured. Automatically retry the read
of the capture file if scapy raises an exception while doing so to
handle rare cases when capture file is read while only partially
written during busy wait. Don't fail assert_nothing_captured if only
junk packets arrived.

Introduce an API which asserts empty capture for interface.
Throw exception in old API if the capture does not exist, thus
making it clear if the test expects packets to arrive or not.
Improve performance by not doing sleeps after starting the packet
generator, rather lazily deleting captures when needed.
Fix wrong usage of packet.show() in various tests.
