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
`comedi_pci_auto_unconfig()` and `comedi_usb_auto_unconfig()` are just
one-line wrappers around `comedi_auto_unconfig()`. Convert them to
inline functions and remove the `BUG_ON()` calls.

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
`comedi_usb_auto_config()` to check that `driver->auto_attach` is
non-null before calling `comedi_auto_attach()` as this check is done by
`comedi_auto_config()` itself (actually by
`comedi_auto_config_wrapper()`). Remove the unnecessary checks.

All the Comedi drivers that call `comedi_usb_auto_config()` have

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).

The newly defined format for the `INSN_CONFIG_DIGITAL_TRIG`

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.)
