5736faa146 Get a reference to the device when "snd/N" MIDI ports are opened 
As the master output level control is not in software any longer the
device needs to opened for adjustments to work.

343f13e33f Make sure devices are properly closed in case of an error 
Fixes possible crashes if the contol device fails, while the audio
device continues to work.

e5f270a89f If available, use the hardware output.level to control the volume. 
With this change, there's a single outputs.level control: either the
hardware one or software one. Consequently, there can't be control
name clashes and there's no need to move hardware's top-level controls
into the "hw/" group.

fab9b7cb7e Call dev_ctlsync(), even if there's no control device 
In the dev_reopen() code-path, the controls of the old device were
removed so all clients must be notified about the controls change.

4f7c000acb Don't forget to notify clients when controls list is ready. 
This is needed because when devices are swapped, clients need to know
when to rebuild their user interface.

As control may have different max values, make sndioctl
expose floats in the [0:1] range.

9b20997f58 Make the device hold a reference to its controls. 
Without this, if "-a on" is used, when the last control client
disconnects, references reach zero and controls are freed.

74ae9cda72 Make the control group a simple string. 
To handle nested devices, just prefix the group with the "dev."
prefix. To avoid namespace conflicts, put program controls in a
new "app" group.

The "master.level" control is renamed to "output.level" to match the
hardware name. This way snd/0 and rsnd/0 end-up with the same control
name.

9ba816d28e Lower the default audio block size from 20ms to 10ms. 
The new default block size is supported by virtually all devices
which allows switching between devices without further configuration.
The buffer size remains the same, so this change won't affect audio
stability.

3935da37f6 Setup channel join/expand after channle mapping conversions. 
The channel mapping conversion calculate the number of channels
actually present on the hardware. This allows to join/expand the right
number of channels.

7cd9c4b0a9 Don't attempt to join/expand nonexistent channels. 
If the (hardware) device has fewer channels than the exposed
sub-device and -jon is used, then mix the samples only to channels
that exist on the device.

0310ad45e9 Revert "Allow switching between devices without disconnecting clients." 
This change was not right: First, upon SIGHUP, next device should be
opened before the old one is closed. Second the migration code doesn't
reinitialize the conversion layer which breaks audio when switching
between devices with different channel counts.

This reverts commit 5bc17e6cea.
