examples: fix dependencies on hash library

The multi_process example do not need rte_hash.
But these examples cannot compile if rte_hash is not available:
- ipsec-secgw (was already protected - no change)
- ipv4_multicast
- l3fwd-power
- l3fwd-vf
- tep_termination
- ip_pipeline

The ip_pipeline example is not disabled because its dependencies
are handled with #ifdef. It may require a separate fix.

information for use by the pmdinfogen tool.  For example:

PMD_REGISTER_DRIVER(ena_driver, ena);

const char this_pmd_name0[] __attribute__((used)) = "ena";

DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);

Which allows pmdinfogen to find the pci table of this driver

Using this pattern, we can export arbitrary bits of information.

Since recently [1], it is not possible to run the dpdk with

layer tries to lock the memory. Using locked memory is mandatory for

EAL memory init allocates all free hugepages of the whole system,
which seen from sysfs, even when applications do not ask so many.
When there is a limitation on how many hugepages an application can
use (such as cgroup.hugetlb), or hugetlbfs is specified with an
option of size (exceeding the quota of the fs), it just fails to
start even there are enough hugepages allocated.

To fix above issue, this patch:
 - Changes the logic to continue memory init to see if hugetlb
   requirement of application can be addressed by already allocated
   hugepages.
 - To make sure each hugepage is allocated successfully, we add a
   recover mechanism, which relies on a mem access to fault-in
   hugepages, and if it fails with SIGBUS, recover to previously
   saved stack environment with siglongjmp().

For the case of CONFIG_RTE_EAL_SINGLE_FILE_SEGMENTS (enabled by
default when compiling IVSHMEM target), it's indispensable to
mapp all free hugepages in the system. Under this case, it fails
to start when allocating fails.

Test example:
  a. cgcreate -g hugetlb:/test-subgroup
  b. cgset -r hugetlb.1GB.limit_in_bytes=2147483648 test-subgroup
  c. cgexec -g hugetlb:test-subgroup \
          ./examples/helloworld/build/helloworld -c 0x2 -n 4

net/ixgbe/base: allow setting MAC anti spoofing per VF

Make ixgbe_set_mac_anti_spoofing() consistent with the other
functions that deal with setting VLAN and Ethertype spoofing by
changing the prototype to accept a VF parameter.

Also change the logic for writing the PFVFSPOOF register to be similar
to the MAC and Ethertype functions.
