This commit adds support in ovs-numa module for reading a user
specified cpu mask, which configures the availability of the cores.
The cpu mask has the format of a hex string similar to the EAL '-c
COREMASK' option input or the 'taskset' mask input. The lowest order
bit corresponds to the first CPU core. Bit value '1' means the
corresponding core is available.
An upcoming patch will allow user to configure the mask via OVSDB.

'numa' and 'socket' are currently used interchangeably in ovs-numa.
But they are not always equivalent as some platform can have multiple
sockets on a numa node. To avoid confusion, this commit renames all
the 'cpu_socket' to 'numa_node'.
