DPDK lcore_id is unsigned. We need to support big values like
LCORE_ID_ANY (=UINT32_MAX). Therefore I am changing the type everywhere
in OVS.

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.

Many of the ovs_numa_*() functions abort the program when the
input cpu socket or core id is invalid. This commit relaxes
the input check and makes these functions return OVS_*_UNSPEC
when the check fails.

'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'.

list_size() yields a size_t, not uint64_t, and these types are different on
32-bit targets.
