ixgbe: fix Rx error stats
Bug fix to remove (rxnfgpc - hw_stats->gprc) which does not account
for phy errors.
hw_stats->gprc is the Number of good (non-erred) Rx packets (from the
network) that pass L2 filtering and has a legal length as defined by
LongPacketEnable. While rxnfgpc is the Number of good (non-erred with
legal length) Rx packets (from the network) regardless of packet
filtering and receive enablement. Thus hw_stats->gprc can be > rxnfgpc
and this calculation should be removed from the calculation of ierrors.
Validated with testpmd by sending packets to the interface without
forwarding enabled - packets should be dropped and the error counters
incremented.

The ring size comes from the host and the driver must use the
actual size passed.
The number of descriptors can be either zero to use the whole
available ring, or some value smaller. This is used to limit
the number of mbufs allocated for the receive ring. If more
descriptors are requested than available the size is silently

Note that the dummy library will be removed in the next release.
When building a combined library, all objects are copied to the same
directory before creating the library itself.
There are a few issues:
- CONFIG_RTE_LIBRTE_MALLOC is not a valid option anymore resulting
in wrong syntax and a compilation failure. Fix it by replacing it
with CONFIG_RTE_LIBRTE_EAL.
- As we kept a dummy library, there are now two objects with the
same name. This means that the proper rte_malloc.o object in eal gets
overwritten by an empty rte_malloc.o object from the dummy malloc lib.
Fix it by changing the name of rte_malloc.o object in the dummy

This problem was discovered when passing invalid PCI id to the

Any failures in rte_devargs_add would cause a core dump because
it would call rte_log() before the the EAL log environment was
initialized. Rather than try and log just remove the messages
and leave it up to the caller to check the return value.
Most of the other failure possibilities are when malloc() fails, and if
that happens any logging that used malloc() would also fail.

The following commit broke vhost sample when it runs in second time:
292959c71961acde0cda6e77e737bb0a4df1559c
It should call api to unregister vhost driver when sample exit/quit, then
the socket file will be removed(by calling unlink), and thus make vhost sample
work correctly in the second time startup.

This patch modifies malloc so it partitions memsegs instead of memzones.
Thus memzones would call malloc internally for memory allocation while
maintaining its ABI.
During initialization malloc sets all available memory as part of the heaps.
CONFIG_RTE_MALLOC_MEMZONE_SIZE was used to specify the default memory
block size to expand the heap. The option is not used/relevant anymore,
