Hi all.

Here is v2 of NBD reconnect, but it is very very different from v1, so,
forget about v1.
The series includes my "NBD reconnect: preliminary refactoring", with
changes in 05: leave asserts (Eric).

The feature realized inside nbd-client driver and works as follows:

There are two parameters: reconnect-attempts and reconnect-timeout.
So, we will try to reconnect in case of initial connection failed or
in case of connection lost. All current and new io operations will wait
until we make reconnect-attempts tries to reconnect. After this, all
requests will fail with EIO, but we will continue trying to reconnect.

To implement nbd reconnect in further patches, we need to distinguish
error codes, returned by nbd server, from channel errors, to reconnect
only in the latter case.

Keep all connection code in one file, to be able to implement reconnect
in further patches.

We have several paranoiac checks for ioc != NULL. But ioc may become
NULL only on close, which should not happen during requests handling.
Also, we check ioc only sometimes, not after each yield, which is
inconsistent. Let's drop these checks. However, for safety, lets leave
asserts instead.

To implement reconnect we need several states for the client:
CONNECTED, QUIT and several CONNECTING states. CONNECTING states will
be realized in the following patches. This patch implements CONNECTED
and QUIT.

QUIT means, that we should close the connection and fail all current
and further requests (like old quit = true).

CONNECTED means that connection is ok, we can send requests (like old
quit = false).

For receiving loop we use a comparison of the current state with QUIT,
because reconnect will be in the same loop, so it should be looping
until the end.

Opposite, for requests we use a comparison of the current state with
CONNECTED, as we don't want to send requests in CONNECTING states (
which are unreachable now, but will be reachable after the following
commits)

This coroutine will serve nbd reconnects, so, rename it to be something
more generic.

As a first step to nbd reconnect, move connection to connection_co
coroutine.

The key point in this patch is nbd_client_attach_aio_context() change:
We schedule to connection_co only if it is waiting for read from the
channel. We should not schedule it if it is some other yield, and if
it is currently executing (we call nbd_client_attach_aio_context from
connection code).

Add two parameters:

reconnect-attempts, which defines maximum number of reconnects, after
  which:
  - open will fail
  - block operations will fail

Note: on open, we actually have reconnect-attempts+1 connection
attempts, the first one is not REconnect.

reconnect-timeout, timeout in nanoseconds between reconnects.

Realization of these options is in the following patch.

Implement reconnect. To achieve this:

1. Move from quit bool variable to state. 4 states are introduced:
   connecting-wait: means, that reconnecting is in progress, and there
     were small number of reconnect attempts, so all requests are
     waiting for the connection.
   connecting-nowait: reconnecting is in progress, there were a lot of
     attempts of reconnect, all requests will return errors.
   connected: normal state
   quit: exiting after fatal error or on close

Possible transitions are:

   * -> quit
   connecting-* -> connected
   connecting-wait -> connecting-nowait
   connected -> connecting-wait

2. Implement reconnect in connection_co. So, in connecting-* mode,
    connection_co, tries to reconnect every NBD_RECONNECT_NS.
    Configuring of this parameter (as well as NBD_RECONNECT_ATTEMPTS,
    which specifies bound of transition from connecting-wait to
    connecting-nowait) may be done as a follow-up patch.

3. Retry nbd queries on channel error, if we are in connecting-wait
    state.

4. In init, wait until for connection until transition to
    connecting-nowait. So, NBD_RECONNECT_ATTEMPTS is a bound of fail
    for initial connection too.
