soreuseport: Fix reuseport_bpf testcase on 32bit architectures
This fixes the following compiler warnings when compiling the
reuseport_bpf testcase on a 32 bit platform:
reuseport_bpf.c: In function ‘attach_ebpf’:
reuseport_bpf.c:114:15: warning: cast from pointer to integer of ifferent size [-Wpointer-to-int-cast]

soreuseport: BPF selection functional test for TCP
Unfortunately the existing test relied on packet payload in order to
map incoming packets to sockets. In order to get this to work with TCP,
TCP_FASTOPEN needed to be used.
Since the fast open path is slightly different than the standard TCP path,
I created a second test which sends to reuseport group members based
on receiving cpu core id. This will probably serve as a better
real-world example use as well.

soreuseport: pass skb to secondary UDP socket lookup
This socket-lookup path did not pass along the skb in question
in my original BPF-based socket selection patch. The skb in the
udpN_lib_lookup2 path can be used for BPF-based socket selection just
like it is in the 'traditional' udpN_lib_lookup path.
udpN_lib_lookup2 kicks in when there are greater than 10 sockets in
the same hlist slot. Coincidentally, I chose 10 sockets per
reuseport group in my functional test, so the lookup2 path was not
excersised. This adds an additional set of tests with 20 sockets.

soreuseport: BPF selection functional test
This program will build classic and extended BPF programs and
validate the socket selection logic when used with
SO_ATTACH_REUSEPORT_CBPF and SO_ATTACH_REUSEPORT_EBPF.
It also validates the re-programing flow and several edge cases.
