In the case where n is a constant 16 bytes, the second load/store is
ignored by the load/store unit - it has neglible/zero cost. In the case
where n is variable and greater than 512 bytes, the extra if (n == 16)
branch has a very small performance impact.

Allow using custom python interpreter via 'PYTHON' env variable.
E.g. env PYTHON=pypy make test.
Get latest pip automatically to properly function in environments,
where old pip is available and a proxy is required. This allows
testing pypy in a centos vagrant-provided vm.

* Populated the trace struct that weren't used before
* Modified and created format functions to format tcp packets and
connections
* Completed the node definitions to add the format_trace function
* Filled the tracing parts with `vlib_add_trace' calls in each tcp node
function
For the nodes in tcp_input.c, there is a verbose trace and a non-verbose
trace. Each packet goes through tcp[4-6]-input which is traced with
`format_tcp_rx_trace', and the other nodes are traced with
`format_tcp_rx_trace_short'.

The missing call to `vnet_session_enable_disable' would cause segfaults
because of an uninitialized session pointer. Just as in the builtin
server the session needs to be enabled for the client.
The `short_help' of the CLI command was also populated with the
arguments that are accepted in the parsing function
`test_tcp_clients_command_fn'.

Handle situation when client tries to connect to multiple hosts/ports
from the same client port. Extend matching to include remote host/port
when searching for existing session and create session for each flow
even when originating from the same client port.

without exhausting file descriptors.

The command set interface placement is supposed to remove the existing
interface placement and add a new interface placement based on the given
options. My quick test for the CLI shows that the old interface placement
continues to exist. But the new interface placement is also added.
The bug exists in vnet_device_input_unassign_thread which checks
the old thread index is the same as the passed thread index and skips the
deletion if they are the same.
The fix is to remove the check which is not supposed to be there.

epoll was supposed to not sleep when timeout
is less than 1ms, but a typo made it not sleep
any time the requested timeout is lower than
1000 seconds (in practice, never...).
This patch replaces "1e3" with "1e-3", which
represents 1ms.

(cherry picked from commit ec06222ae1)
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.
