This reverts commit 4cd97e5ad7.
We should actually check the return value of sr_gpio_setval_export().

Add LIBUSB_CALL where needed to avoid warnings such as the following:

Both ina2xx and tmp401 linux drivers used by baylibre-acme expose
the standard hwmon update_interval attribute, which affects the internal
update interval of the chip.
When setting samplerate for data acquisition try to modify this
attribute accordingly.

PROBE_FACTOR and POWER_OFF options are advertised for all ACME probes
(channel groups) regardless of whether they actually have given capability.
Check these options in config_list() at runtime and only advertise them
for probes which support them.

Tested on an MSO1104Z with firmware 00.04.02.SP4.
The analog channels are captured correctly. For the MSO series, with digital
channels, there are two outstanding issues:
1. Logic data is retrieved per-channel, one byte per sample, with the value
in the LSB of each byte. The current datafeed logic format doesn't allow
this format to be passed on directly. I suggest we resolve that rather than
making the driver buffer and interleave the data.
As stands, the code will retrieve data for all channels and pass it onto
the datafeed with unitsize=1. Channel D0 can used correctly if selected
alone. For other channels, data is passed to the frontend but the API does
not provide a way to associate it with the correct channel.
2. Channels CH3 and CH4 are multiplexed with D0-7 and D8-15 respectively, so
enabling these is mutually exclusive. We don't currently have a way to
express this constraint to the frontend.
