Load balance sockets with new SO_REUSEPORT_LB option
This patch adds a new socket option, SO_REUSEPORT_LB, which allow multiple programs or threads to bind to the same port and incoming connections will be load balanced using a hash function. Most of the code was copied from a similar patch for DragonflyBSD. However, in DragonflyBSD, load balancing is a global on/off setting and can not be set per socket. This patch allows for simultaneous use of both the current SO_REUSEPORT and the new SO_REUSEPORT_LB options on the same system. Required changes to structures Globally change so_options from 16 to 32 bit value to allow for more options. Add hashtable in pcbinfo to hold all SO_REUSEPORT_LB sockets. Limitations As DragonflyBSD, a load balance group is limited to 256 pcbs (256 programs or threads sharing the same socket).
