ALSA amidi(1) and aseqdump(1) can be used to dump MIDI instead of
manually dumping MIDI messages in the driver.  The advantage of using
these existing tools is that can be used at run-time rather than
compile-time.

The usbmon feature should be used instead of manually dumping control
URBs.  There are a few advantages to using usbmon:

 * Can be turned on/off at runtime
 * Provides full USB-level traffic
 * tcpdump and wireshark support for powerful analysis
 * No driver-specific code is required

Apart from the somewhat unnecessary `BUG_ON()` calls,
`comedi_pci_auto_config()` and `comedi_usb_auto_config()` are just
one-line wrappers around `comedi_auto_config()`, and

No comedi drivers set the `attach_pci()` or `attach_usb()` handlers in
their `struct comedi_driver` any longer as they have all been replaced
with an `auto_attach()` handler.  Also, no code calls the `attach_pci()`
or `attach_usb()` handlers any longer.  Remove them from `struct
comedi_driver`.

`comedi_auto_config()` just calls internal function
`comedi_auto_config_helper()`, passing it a wrapper function
`comedi_auto_config_wrapper()` to handle the specifics of checking and
calling the low-level comedi driver's `auto_attach()` handler.

Since there are no other callers of `comedi_auto_config_helper()` or
`comedi_auto_config_wrapper()`, combine everything into the single
exported function `comedi_auto_config()`.

Change the ordering of the check for existence of the low-level comedi
driver's `auto_attach()` handler and the allocation of the comedi minor
device number.  This means the log message warning of the absence of the
handler now has to be refer to the hardware device instead of the
not-yet-allocated comedi device.

There is no need for `comedi_pci_auto_config()` and

The 'addi_apci_1032' driver recently started supporting the
`INSN_CONFIG_DIGITAL_TRIG` configuration instruction, but as no other
drivers were using it before, there was no existing practice of how the
instruction should look.

Define the format to be something a bit more configurable.  In
particular, a subdevice might have more than one trigger requiring an ID
and/or `COMEDI_EV_...` flags to disambiguate them, a trigger might have
more than 32 inputs, and a trigger might need several
`INSN_CONFIG_DIGITAL_TRIG` configuration instructions to configure
completely (if there are more than 32 inputs or if it uses a combination
of edge-triggered and level-triggered inputs).

Conform to the new definition of the `INSN_CONFIG_DIGITAL_TRIG`
configuration instruction.

Return an error if the 'trigger number' in `data[1]` is non-zero or if
the configuration operation in `data[2]` is not supported.  Deal with
the 'left-shift' amount in `data[3]`.

The trigger's input channels can only be configured as a set of rising
and falling edges ('OR' mode) or as a set of high and low levels ('AND'
mode).  Preserve the old input channels to the right of the 'left-shift'
value except when switching modes.

(The 'left-shift' support is a bit of an overkill for this driver since
the trigger only has 16 input channels.)
