Robert Watson 3f0bfcccfd Further clean up sorflush:
- Expose sbrelease_internal(), a variant of sbrelease() with no
  expectations about the validity of locks in the socket buffer.
- Use sbrelease_internel() in sorflush(), and as a result avoid intializing
  and destroying a socket buffer lock for the temporary stack copy of the
  actual buffer, asb.
- Add a comment indicating why we do what we do, and remove an XXX since
  things have gotten less ugly in sorflush() lately.

This makes socket close cleaner, and possibly also marginally faster.
