vlib: Handle race in thread barrier processing

When CLIB_DEBUG is enabled, vlib_foreach_main macro asserts that
vlib_main it currently looks at is safely parked in barrier, by
checkling that vlib_main->parked_at_barrier is not 0.
Unfortunately, the check is racy - workers first increment the
atomic counter to indicate that they have reached the barrier
and _then_ set this_main->parked_at_barrier to 1. For the last
worker to suspend this opens the race - main thread is free
to execute and assert immediately after atomic counter has been
incremented, before worker gets to write to own parked_at_barrier.

Fix this by simply swapping the order of two operations.

session tcp: infra for transports to send buffers

Type: feature

Add infra that allows transpors to enqueue pending buffers without the
need to build and manage their own pending frames. An important benefit
is the fact that buffer wire/tx ordering is ensured by session layer.

vlib: linux: fix wrong iommu_group value issue when using dpdk-plugin

When VPP work with dpdk-plugin, linux_vfio_main_t->container_fd is always -1
since it never have chance to run open("/dev/vfio/vfio") to get the fd.

But this lead to a potential issue of VPP, that is, when start VPP without
uio-driver field setup in /etc/vpp/startup.conf, VPP will run to automatical
select uio driver in vlib_pci_bind_to_uio() and the function depend on
iommu_group value to decide to work on vfio or vfio-noiommu mode.

Since in vlib_pci_get_device_info() have the condition container_fd != -1,
so the iommu_group value will be always -1 at this scenario, this caused
that VPP mistake to run with vfio-noiommu driver on intel_iommu=on state.

Actually in order to get iommu_group and iommu_group/name value, no need to
depend on linux_vfio_main_t->container_fd value, so the fix remove the
condition lvm->container_fd != -1, then it can get the correct iommu_group
value.

devices: vhoost cpu->copy array overflow on tcp jumbo frame (65535 bytes)

We reserve 40 slots in cpu->copy array prior to copy out to avoid overflowing
the array. However, 40 is not enough for the jumbo frame because desceiptor
buffer len is likely at 1536. Change the reserve to 200 and add ASSERT to avoid
encountering the same problem in the future.

tests: add PID of VPP under test to API dump filename for the test

Some testclasses (e.g. IPSec) have methods with the same names,
this causes a race when running in parallel to save the API and
move it into the test's directory - the name of the file has
only the test method name as a discriminator.

Saving two traces from two VPP instances "succeeds", in that
it silently overwrites the file. But only one mv operation
works - the other gives an error "file not found" and fails the test.

Solution: add the PID of VPP under test to the API dump filename,
this way the filenames become guaranteed unique and the race is avoided.

tests: make pg_start() wait until pg completes

A sizable number of tests call pg_start() to get the packets flowing and then
immediately expect to have the entirety of the packets gone through.
This works on powerful and unstressed hardware, but fails in beautifully random
ways under load.

This also necessitates the complicated logic of remembering the "zombie captures",
then sleeping for some time before cleaning them up....

The solution is simple: in pg_start(), start the generators, wait till they
all finish, clean up, done.

tests: log error which happens during connect and wait longer for stats socket

Intermittently, a test would start VPP, but no testcases would execute.
This would be more probable apparent during the high load or if there
is another testcase dumping the core at that moment.
Adding the logging to the connection revealed it was the stats socket
connection erroring with error -2. Increasing the deadline
from 3 seconds to 5 minutes has eliminated this error.

on this activity, just in case the things go terribly wrong.

Fix a day-1 bug, possibly dating back as far as 2002. The zap64() game

That's fine *unless* the 8-byte fetch happens to cross a page boundary
into unmapped or no-access space.
