Fix up xprt_connect_status: the soft timeout logic was clobbering tk_status,
so TCP connect errors were not properly reported on soft mounts.
Test-plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP.

In __xprt_lock_write() we check to see if `task' is NULL, but in other places
we just go and dereference it.
`task' shouldn't be NULL anyway, so remove this test.
This defect was found automatically by Coverity Prevent, a static analysis
tool.

Make the socket transport kick the event queue to start socket connects
immediately. This should improve responsiveness of applications that are
sensitive to slow mount operations (like automounters).
We are now also careful to cancel the connect worker before destroying
the xprt. This eliminates a race where xprt_destroy can finish before
the connect worker is even allowed to run.

Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. Hard-code impossibly small connect timeout.

When the network layer reports a connection close, the RPC task
waiting to reconnect should be notified so it can retry immediately
instead of waiting for the normal connection establishment timeout.
This reverts a change made in 2.6.6 as part of adding client support
for RPC over TCP socket idle timeouts.
Test-plan:
Destructive testing with NFS over TCP mounts.

Cancel autodisconnect requests inside xprt_transmit() in order to avoid
races.
Use more efficient del_singleshot_timer_sync()

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
