This ensures consistent handling of the SR_CONF_SCAN_OPTIONS and
SR_CONF_DEVICE_OPTIONS (with sdi NULL or non-NULL) config keys
and also reduces copy-pasted boilerplate in the drivers a bit.
This function does not handle channel-group specific items, that's
very driver-specific and thus left to the individual drivers.
Also move some generic checks and error messages from the drivers into
the sr_config_list() wrapper.
The HW simply stops sending data on overflows, so if we receive no data
in one second, we abort the acquisition. We also need to allocate more
buffers to support higher sample rates.
Until now, clear_helper() callbacks for std_dev_clear_with_callback()
were expected to g_free(devc), but not all of them did that.
Have std_dev_clear_with_callback() unconditionally g_free(sdi->priv)
(i.e., devc), regardless of whether a clear_helper() callback was
provided or not. It was doing g_free(sdi->priv) when no callback
was provided already anyway.
This makes the individual drivers' clear_helper() implementations
shorter and prevents errors such as missing g_free(devc) calls.
This works, because all drivers either call std_dev_clear_with_callback()
directly, or indirectly via std_dev_clear().
This also allows us to remove some no-longer needed dev_clear()
and clear_helper() implementations that only did g_free(devc)
in favor of std_dev_clear().
Be explicit and consistent in the drivers about which dev_clear function
will be called to avoid confusion and inconsistencies.
Drop some open-coded implementations of std_dev_clear().
Drop unneeded log messages, add some others that might be useful,
document which ones we're intentionally not emitting.
Don't log "$operation successful" type of messages in most cases,
that's too verbose; logging failures only is sufficient there.

The asix-sigma driver was reported to fail in combination with newer
libftdi versions, because the firmware upload routine opened again an
already opened device, and then failed to claim the interface. Which was
not fatal before with previous libftdi versions.
Remove the redundant open call. Remove the local FTDI context variable,
which brings the firmware upload routine in line with all other calls
that communicate to the USB device.
This fixes bug #471.

The asix-sigma driver supports different samplerates, which will involve
different firmware images and will affect the number of available logic
channels as well as their memory layout in downloaded sample data.
Make sure to only store the configuration's parameters after the setup
of that configuration has successfully completed, and make sure to store
a consistent set of parameters. Specifically don't change the number of
channels when the firmware upload failed.
This fixes part of bug #471.
Suggested-By: Marian Cingel <cingel.marian@gmail.com>
The firmware upload code paths in the asix-sigma driver used to return
either the SR_OK code, or the magic number 0 for error conditions. Which
happens to be identical and cannot be told apart by callers.
Provide proper SR_ERR return codes for error conditions, such that
callers can tell whether the firmware upload succeeded.
This fixes part of bug #471.
