Issue:
Let iperf3 server run via ldp and vcl on top of vpp's host stack. If
iperf3 client connects this iperf3 server with tcp MSS setting option,
iperf3 server will always crash.
Root cause:
When MSS option is specified by iperf3 client, iperf3 server will
recreate the listening socket firstly, then call setsockopt() to set MSS
immediately. Iperf3 code can be referred here:
58332f8154/src/iperf_tcp.c (L186).
However, in vcl layer vpp_evt_q of this recreated session is not
allocated yet. So iperf3 server crashes with vpp_evt_q null pointer access.
Fix:
Add session vpp_evt_q null pointer check in vcl_session_transport_attr().
Add a vcl test case for this MSS option scenario.

Drop pycodestyle for code style checking in favor of black. Black is
much faster, stable PEP8 compliant code style checker offering also
automatic formatting. It aims to be very stable and produce smallest
diffs. It's used by many small and big projects.
Running checkstyle with black takes a few seconds with a terse output.
Thus, test-checkstyle-diff is no longer necessary.
Expand scope of checkstyle to all python files in the repo, replacing
test-checkstyle with checkstyle-python.
Also, fixstyle-python is now available for automatic style formatting.
Note: python virtualenv has been consolidated in test/Makefile,
test/requirements*.txt which will eventually be moved to a central
location. This is required to simply the automated generation of
docker executor images in the CI.

This patch addresses the functionality that is
missing for distributed make test source files.
In addition it extends the concept of colocating
test source code with functional source code
(eg. src/vcl/test). It also cleans up deficiencies
in the make test makefiles.
NOTE: Due to the way sphinx document tools work,
all test, all of the make test python code is
gathered using soft links into the directory:
.../build-root/build-test/src
Change summary:
- Remove 'make test' help details from
main makefile help output to reduce clutter
and redundant help output
- Move all generated build output to
.../build-root/build-test
- Move test_vcl.py as first usecase for
distributed core feature make test code
- Add test-wipe-all target and fix wipe targets
to remove all generated files
- Fix 'make test-doc' to generate module
documentation for all source files
- Remove unused targets in test/doc/Makefile
- Fix 'make test-shell'
- Fix test/ext Makefile to not generate
bogus output

Enhance the route add/del APIs to take a set of paths rather than just one.
Most unicast routing protocols calcualte all the available paths in one
run of the algorithm so updating all the paths at once is beneficial for the client.
two knobs control the behaviour:
is_multipath - if set the the set of paths passed will be added to those
that already exist, otherwise the set will replace them.
is_add - add or remove the set
is_add=0, is_multipath=1 and an empty set, results in deleting the route.
It is also considerably faster to add multiple paths at once, than one at a time:

Have vcl poll and wait on the event message queues as opposed to
constantly polling the session fifos. This also adds event signaling to
cut through sessions.
On the downside, because we can't wait on multiple condvars, i.e., when
we have multiple message queues because of cut-through registrations, we
do timed waits.
