Nicolas Lacasse 012102eefd Pass OpenTruncate to gofer in Open call when opening file with O_TRUNC.
Note that the Sentry still calls Truncate() on the file before calling Open.

A new p9 version check was added to ensure that the p9 server can handle the
the OpenTruncate flag. If not, then the flag is stripped before sending.

Jamie Liu e9af227a61 Fix p9 integration of flipcall.
- Do not call Rread.SetPayload(flipcall packet window) in p9.channel.recv().

- Ignore EINTR from ppoll() in p9.Client.watch().

- Clean up handling of client socket FD lifetimes so that p9.Client.watch()
  never ppoll()s a closed FD.

- Make p9test.Harness.Finish() call clientSocket.Shutdown() instead of
  clientSocket.Close() for the same reason.

- Rework channel reuse to avoid leaking channels in the following case (suppose
  we have two channels):

  sendRecvChannel
    len(channels) == 2 => idx = 1
    inuse[1] = ch0
                                        sendRecvChannel
                                          len(channels) == 1 => idx = 0
                                          inuse[0] = ch1
    inuse[1] = nil
  sendRecvChannel
    len(channels) == 1 => idx = 0
    inuse[0] = ch0
                                          inuse[0] = nil
    inuse[0] == nil => ch0 leaked

- Avoid deadlocking p9.Client.watch() by calling channelsWg.Wait() without
  holding channelsMu.

- Bump p9test:client_test size to medium.

Michael Pratt df5d377521 Remove go_test from go_stateify and go_marshal
They are no-ops, so the standard rule works fine.

Adin Scannell 75cd70ecc9 Track paths and provide a rename hook.
This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.

Zhaozhong Ni be7fcbc558 stateify: support explicit annotation mode; convert refs and stack packages.
We have been unnecessarily creating too many savable types implicitly.
