History
Philo Lu accdd51dc7 net/udp: Add a new struct for hash2 slot 
Preparing for udp 4-tuple hash (uhash4 for short).

To implement uhash4 without cache line missing when lookup, hslot2 is
used to record the number of hashed sockets in hslot4. Thus adding a new
struct udp_hslot_main with field hash4_cnt, which is used by hash2. The
new struct is used to avoid doubling the size of udp_hslot.

Before uhash4 lookup, firstly checking hash4_cnt to see if there are
hashed sks in hslot4. Because hslot2 is always used in lookup, there is
no cache line miss.

Related helpers are updated, and use the helpers as possible.

uhash4 is implemented in following patches.
