All those options are currently applied only to power-supplies
but they could apply as well to electronic loads, except for the
fact that electronic loads channels are called inputs and not
outputs.
Also when you think about an SMU (or any kind of 4-quadrants
power-supply), their channels can both source and sink current,
so they can be considered as input as much as output.
Those SR_CONF_* are thus renamed so that they can be used in all
those situations.
This requires sr_hw_cleanup_all() and sanity_check_all_drivers()
to also take a context.
The (runtime) generation of the driver list now happens in sr_init()
and sr_driver_list() always returns that pre-generated list. This fixes
a segfault when (correctly) invoking multiple sr_init() and sr_exit()
calls with different contexts (caught by the unit tests).
This fixes bug #565.
Add new configuration option allowing to modify the probe factor
for oscilloscopes and power-monitors.

Inlining can only happen in the same compilation unit where the
function was defined, so there is no sense declaring an inline
function in a header if this function is not defined in this
same header.
This fixes the following gcc-5 warning:
In file included from include/libsigrok/libsigrok.h:1066:0,
from src/version.c:21:
include/libsigrok/proto.h:36:20: warning: inline function 'sr_rational_set' declared but never defined
SR_API inline void sr_rational_set(struct sr_rational *r, uint64_t p, uint64_t q);

Add new error code which can be used to notify the user about
general input/output errors.

- 'struct sr_input *' variables are consistently named 'in'.
- 'struct sr_input_module *' variables are consistently named 'imod'.
- 'struct sr_output *' variables are consistently named 'o'.
- 'struct sr_output_module *' variables are consistently named 'omod'.
Add new config options to libsigrok - 'averaging', which allows to
enable averaging of samples and 'avg_samples' for setting the number
of samples to be averaged over in each cycle.

The automatic selections of the measured quantity and equivalent circuit
model are more part of the configuration of the meter than attributes
of the measurement result. To reflect this, model them as config keys
instead of mqflags. This allows a driver that supports remote control to
implement 'set' method for them and has the additional benefit of saveing
two flag bits.
Add flags for indicating that the meter has selected the measured
quantitiy and/or the used measurement model automatically. These
are similar to the existing auto-range flag.
Add 'SR_MQ_DIFFERENCE' quantity for reporting relative difference
between the current measurement and the reference value. The value
of this quantity will normally be reported in percents. Add also
the flag 'SR_MQFLAG_REFERENCE' for indicating that the reported
value is not the current measurement but the reference value instead.
Add parallel and serial model inductance, capacitance and resistance
for LCR meter measurements. Add also secondary quantities many LCR
meters calculate, namely dissipation factor, quality factor and phase
angle.
Add degrees and henrys to the list of supported units. Degree is
an unit of plane angle where one degree is 1/360th of a full circle.
Henry is the SI unit of inductance.
This signifies to the module instance no more input will come. This
will cause the module to process any data it may have buffered. The
SR_DF_END packet will also typically be sent at this time.
