The new methods wrap the new libsigrok C API helper functions and eliminate
the need to pass complex types back to the user and wrap them with SWIG.
Fixes bugs #479 and #480.
This function replaces the pattern of calling config_list() with
SR_CONF_DEVICE_OPTIONS to obtain a list of device options. Note
that this does not include the SR_CONF_{GET,SET,LIST} bitmask,
which is now retrieved for a specific key by calling
sr_dev_config_capabilties().
Refactor handling the size of modbus_devs, so it doesn't produce a build
warning and still allows the compiler to remove unused code.
This fixes bug #637. It could be reverted once modbus_devs
unconditionally has a member in the struct.

In some situations, the reply to the *IDN? command contains an
additional trailing 0x01 byte for unknown reasons.
This issue seems to be reproducible by changing the voltage using the knobs
on the device, then turning on the output and turning it off again.
The next korad-kaxxxxp scan() operation would contain the trailing 0x01
byte, which would lead to the detection of the device in libsigrok no
longer working until the next power-cycle.
Work around this issue by treating both the ID string with and without
the trailing 0x01 byte as valid.
This is a desperate measure to improve the success rate of device
initialization even after it got into a bad state. Combine this
with a reduced USB timeout (1 second) so that if it fails, it fails
quickly. Also ignore USB errors from the initial dummy read of the
device test ID.
Detect whether the FX2 firmware of the LWLA device exhibits the
short transfer bug. If so, work around the problem by limiting
reads to at most 64 bytes at a time. This slows down the memory
read after acquisition quite noticably, but makes the device
usable even in adverse conditions.
Reduce the number of long registers read in bulk during status
polling from 10 to 5. The LWLA1034 driver used to do that already
in an earlier iteration, which was then changed to be more like
the original vendor software. The reason for bringing it back now
is that it reduces the response size to 40 bytes, which works
around the spurious 64 byte limit bug in the FX2 firmware of the
LWLA devices.
The sr_input_dev_inst_get API documentation guarantees an input is fully
initialized as soon as the device instance is returned. An sdi
implementation should not set sdi_ready any earlier.
This fixes parts of bug #387.
The source file enum.hpp was not found when not building in the source
tree. Also, extraction of the brief description did not work correctly
when there was additional XML markup inside the <para> element.
The sixth character from ISET? is read and discarded. If the device is
turned off and on again, this won't be there and causes 10 ms delay in
every ISET? Luckily, this value isn't queried that often. To get the
sixth byte, the *IDN? command has to be issued before ISET?.
