When blacklisting network adapters that share a PCI bus address with multiple
ports such as Mellanox ConnectX-3 (librte_pmd_mlx4), RTE applications
enter infinite loops while probing PCI devices.
This commit removes this probe on subsequent instances for blacklisted devices
that have RTE_PCI_DRV_MULTIPLE set.

Need to change PCI code to support multiple I/O regions on a single device.
Some devices like VMXNET3 have multiple PCI memory regions, and some
have none.

The VMWare TSC mapping uses a hook to RDPMC to read the physical TSC
in the case of VMware ESXi.

Introduce new option --vmware-tsc-map, ignored if
CONFIG_RTE_LIBRTE_EAL_VMWARE_TSC_MAP_SUPPORT is not set.
Default is CONFIG_RTE_LIBRTE_EAL_VMWARE_TSC_MAP_SUPPORT=y.
if CONFIG_RTE_LIBRTE_EAL_VMWARE_TSC_MAP_SUPPORT is set:
rte_rdtsc() selects at runtime between Vmware mapping of
TSC or native TSC
else
rte_rdtsc() always uses native rdtsc.
When running DPDK on VMware guest, enable --vmware-tsc-map to
read the physical TSC.
Caution: ESXi should pass monitor_control.pseudo_perfctr = TRUE
othewise it results in general protection fault.

Both logging and calls to panic are never in the critical path.
Use the GCC attribute cold to mark these functions as cold,
which generates more optimised code.

By default, DPDK based applications would only allow logging
to syslog as "rte", DAEMON; but for any production application more
control is desired to allow using actual application name and
overriding the facility.

The original definitions prevent external programs/libraries from compiling
without warnings when using these headers and -std=gnu99 (relaxed C99 mode).

Drivers with the flag RTE_PCI_DRV_MULTIPLE enabled will be bound several
times to the same device until they return an error.
These drivers must internally keep track of each device state in order for
this to work reliably.
This flag currently required for Ethernet adapters with several physical
ports but a single address on the PCI bus.

Add a driver reference (if available) to every PCI devices,
even when blacklisted. This information is made available in the global
device_list variable so users know which network devices are managed or
ignored.

The '\0' is written outside the bounds of the log buffer, which can
result in memory corruption or display issues with log messages.
Use a new constant LOG_BUF_SIZE to store the effective size of the
buffer in struct log_history.
