On SMP architecture, '/sys/bus/pci/devices/<devices id>/numa_node' file
will return -1 as a valid value if it does not have any NUMA node information.
Using -1 as a valid node id to access data structures will cause memory issue.
Fix the error by setting the value of numa_node to 0 if '/sys/bus/pci/devices/
<devices id>/numa_node' returns -1 and it is a SMP system.

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.

If no Linux PCI driver module is loaded, then the driver_name in the PCI
info struct is NULL. This can triggers crash when checking driver name
eg. in vlib_pci_device_open().
Default to "<NONE>" as driver name, which should never match.

The vlib init function subsystem now supports a mix of procedural and
formally-specified ordering constraints. We should eliminate procedural
knowledge wherever possible.
The following schemes are *roughly* equivalent:
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
clib_error_t *error;
... do some stuff...
if ((error = vlib_call_init_function (init_runs_next)))
return error;
...
}
VLIB_INIT_FUNCTION (init_runs_first);
and
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
... do some stuff...
}
VLIB_INIT_FUNCTION (init_runs_first) =
{
.runs_before = VLIB_INITS("init_runs_next"),
};
The first form will [most likely] call "init_runs_next" on the
spot. The second form means that "init_runs_first" runs before
"init_runs_next," possibly much earlier in the sequence.
Please DO NOT construct sets of init functions where A before B
actually means A *right before* B. It's not necessary - simply combine
A and B - and it leads to hugely annoying debugging exercises when
trying to switch from ad-hoc procedural ordering constraints to formal
ordering constraints.

clib_file_index is 0 if it is not initialized result in
following assertion on deleteing the pci device.
vpp/src/vppinfra/file.h:122 (clib_file_del_by_index) assertion `! pool_is_free (um->file_pool, _e)' fails
This patch fixes the issue by initializing the clib_file_index to -1.

For some reason, GCC 8 in debian is pickier than GCC 8 in ubuntu. It complains
about things in strncpy like this
/home/sluong/vpp/src/vlib/linux/pci.c:485:7: error: ‘strncpy’ output may be
truncated copying 15 bytes from a string of length 255 [-Werror=stringop-truncation]
strncpy (ifr.ifr_name, e->d_name, sizeof (ifr.ifr_name) - 1);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/sluong/vpp/src/vlib/linux/pci.c: At top level:
It also complains similar things in string_test.c
The fix in pci.c is to convert strncpy to use clib_strncpy
The fix in string_test.c is condiational compile the complained code for GCC 8.

Doing strncpy(ifr.ifr_name, s, sizeof(ifr.ifr_name)) will cause
a warning about string truncation with GCC 8 (and other tools).
Fix this by using sizeof(ifr.ifr_name) - 1. Also, there is no
need to manually zero the end of the string since the whole
ifr structure is already zeroed by memset.

Few devices provide PCI bar region(s) through I/O.
If any such device driver opens I/O "fd" to read and write,
needs to close it, when pci device is going to be deleted.

gcc8 introduced a new warning (Wstringop-truncation) which in our case
is being treated as error.
Disabling the warning globally might introduce bugs related to string
truncation which are not desired by the developer (e.g. bug).
Instead, this patch disables the warning only for those occurences
which have been verified to be non-bugs but the desired behaviour as per
developer will.

Old code was only allowing PCIdevices to be scanned during startup,
now driver can open and close device without restart of vpp.

While comment properly says that only first 64 bytes can be read, actual
