rwatson 82295697cd Extend coverage of SOCK_LOCK(so) to include so_count, the socket
reference count:

- Assert SOCK_LOCK(so) macros that directly manipulate so_count:
  soref(), sorele().

- Assert SOCK_LOCK(so) in macros/functions that rely on the state of
  so_count: sofree(), sotryfree().

- Acquire SOCK_LOCK(so) before calling these functions or macros in
  various contexts in the stack, both at the socket and protocol
  layers.

- In some cases, perform soisdisconnected() before sotryfree(), as
  this could result in frobbing of a non-present socket if
  sotryfree() actually frees the socket.

- Note that sofree()/sotryfree() will release the socket lock even if
  they don't free the socket.
