NEX-1643 dtrace provider for smbsrv
Also illumos 1841:
 DTrace smb provider was mis-implemented, doesn't exist.
Add back handlers for read/write raw, so that
 legacy dtrace consumers can find the probes.
Kill extra arg in smb_negotiate
Fix missing "done" probe with smb_notify
Add example consumer: smb-trace.d
fix soi_pid
