SDP: SYSCTL_DECL SDP-wide sysctl node in header

This allows use of the shared _net_inet_sdp in more than one compilation
unit. (Nothing in-tree uses this today, but some of Isilon's out-of-tree
SDP enhancements add sysctls below the node.)

sdp: Use an mbufq for received control packets.

This is simpler than the hand-rolled queue, and fixes a use-after-free.

Prepare for activation of LinuxKPI module parameters as read-only
tunable SYSCTL's. Linux module parameters are associated with the
module they belong to. FreeBSD does not share this concept of a parent
module. Instead add macros which define the prefix to use for the
module parameters in the LinuxKPI consumers.

While at it convert all "bool" LinuxKPI module parameters to "byte"
type, because we don't have a "bool" type of SYSCTL in FreeBSD.
