In many application there are no timers queued, and the call to
rte_timer_managecan be optimized in that case avoid reading HPET and
lock overhead.

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.

When a memory address must be read, for instance a [mapped] PCI register,
the read value is assigned to a local variable that is not used after,
as for instance:
x = *((uint8_t *) mem_addr);
Such instructions do not compile with gcc 4.6.
The fix consists in adding the "volatile" attribute to the accessed data type
and to not assign the read value:
*((volatile uint8_t *) mem_addr);

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.
