95c2da7c25 lb: Fix src_ip_sticky evaluation bug in per-port-vip case.
Before this fix, the src_ip_sticky flag was passed as an argument to
the lb_node_get_hash function, which computes a hash value for a packet.
However, in per-port-vip case, the value of src_ip_sticky flag may be
different for each port number. As a result, the value is the same for
all port numbers, even though it is a per-port-vip case.

This commit fixes the src_ip_sticky evaluation by delaying it until the
packet is received, so that the correct value is obtained. Also, the
unit test case has been enhanced for this bug fix.

The steps to reproduce this bug are described below:

613e6dc0bf lb: add source ip based sticky load balancing
This patch adds source ip based sticky session, which is already
implemented in many hardware LBs and software LBs. Note that sticky
sessions may be reset if the hash is recalculated as ASs are added
or deleted.

Since this feature is unrelated to the other existing options, the
lb_add_del_vip API version has been upgraded to v2 and a new option
"src_ip_sticky" has been added.

d9b0c6fbf7 tests: replace pycodestyle with black
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.

097fa66b98 fib: fib api updates
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:

8e66b9bf4b Use crc32 wrapper (VPP-1086)
This allows arm platforms to also take advantage of crc32 hardware
acceleration.

* add a wrapper for crc32_u64. It's the only one really used. Using it
  instead of a call to clib_crc32c() eases building symmetrical hash
  functions.
* replace #ifdef on SSE4 by a test on clib_crc32c_uses_intrinsics.
  Note: keep the test on i386
* fix typo in lb test log

dab231a11e make test: improve handling of packet captures
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.

f588f35d66 Test: Add test case for Load Balancer plugin
This adds a basic test for the four existing encap modes
for the load balancer plugin.
- ip4 over gre4
- ip4 over gre6
- ip6 over gre4
- ip6 over gre6

Apparently, scapy does not support GRE and IPv6 combinations.
Hence, those tests do send packets through VPP, but only
ip4 over gre4 output is actually parsed and verified.
