  ovs-numa: Remove non-linux stubs.

Instead of having static inline stubs for non linux platform we can use
the implementations in ovs-numa.c.  With one small change to
ovs_numa_dump_cores_on_numa(), they will behave exactly like the
stubs for the non-linux case, because 'found_numa_and_core' will be
false and the socket and cpu hmaps will be empty.

There are a few places where conditional compilation is required: the
code that parses the linux specific sysfs entries and its dependencies.
It requires opendir() and readdir() and doesn't make sense outside of
linux anyway.

This change is required to have a cross-platform ovs-numa dummy
implementation for testing.

  Log Message:
  -----------
  ovs-numa: Introduce function to set current thread affinity.

This commit moves the code that sets the pmd threads affinity from
netdev-dpdk to ovs-numa.  There's one small part left in netdev-dpdk, to
set the lcore_id.

Now dpif-netdev will call both modules (ovs-numa and netdev-dpdk) when
starting a pmd thread.

This change will allow having a dummy implementation of the set affinity
call, for testing purposes.

  Log Message:
  -----------
  vswitchd: Add --dummy-numa command line option.

This option is used to initialize the ovs_numa module with a fake
configuration and to avoid pthread_setaffinity_np() calls.  It will be
useful to test dpif-netdev with pmd threads.

Since it is only used for testing it is not documented in the man pages.
