sctp: use sb_avail() when accessing sb_acc for reading

sctp: cleanup, no functional change intended

sctp: improve path verification

sctp: improve consistency

sctp: improve locking

sctp: improve stopping of timers

sctp: hold the inp lock while calling ip6_output

if_vtnet: improve dumping a kernel

As suggested by Mark, disable software LRO for the vtnet interface during dumping.

sctp: fix typo introcuded in last commit

sctp: don't wakeup 1-to-1 listening sockets for data or notifications

sctp: don't keep a pointer to a freed stcb around

sctp: improve locking

sctp: fix parameter type in NAT status message

sctp: remove a mutex not used anymore

sctp: use variable names in a consistent way

We talked about this at the FreeBSD transport call. glebius@ suggested to follow markj@'s suggestion to disable TCP LRO when dumping the kernel. tuexen@ will look at it.

I suspect the right solution is to somehow ensure that LRO is not in use when dumping. Either by checking dumping in vtnet_software_lro() or (probably better) clearing the software LRO flag in the vtnet softc in vtnet_debugnet_event().
