tc: Set 'no_percpu' flag for compatible actions
Recent changes in Linux kernel TC action subsystem introduced new
TCA_ACT_FLAGS_NO_PERCPU_STATS flag. The purpose of the flag is to request
action implementation to skip allocating action stats with expensive percpu
allocator and use regular built-in action stats instead. Such approach
significantly improves rule insertion rate and reduce memory usage for
hardware-offloaded rules that don't need benefits provided by percpu
allocated stats (improved software TC fast-path performance). Set the flag
for all compatible actions.
Modify acinclude.m4 to use OVS-internal pkt_cls.h implementation when
TCA_ACT_FLAGS is not defined by kernel headers and to manually define
struct nla_bitfield32 in netlink.h (new file) when it is not defined by
kernel headers.
