SR_CONF_CONTINUOUS is used to check if a device supports continuous sampling
or not. As such, the type boolean is better suited.

g_variant_print() allocates memory during call. Save the pointer
so that it can be free'd afterwards.

High precision multimeters have a special setting, called "number of
powerline cycles" (NPLC) which determines the integration time of the
ADC in terms of the power line period. Some devices need their NPLC
adjusted from the default value before they can measure at their full
rated precision.
Since Autoconf places some important feature flags only into the
configuration header, it is necessary to include it globally to
guarantee a consistent build.
A few of these were pretty serious, like missing arguments,
passing integers where a string was expected, and so on.
In some places, change the types used by the code rather than
just the format strings.
The need to make this a list no longer applies.
SR_T_MQ is thus a type consisting of a tuple with two elements: the first
item is the MQ (type G_VARIANT_TYPE_UINT32), and the second is the MQ
flags value (G_VARIANT_TYPE_UINT64).
This type consists of an array, with each item a two-member tuple,
representing an MQ/MQflags pair: the first item is the MQ (type
G_VARIANT_TYPE_UINT32), and the second is the MQ flags value
(G_VARIANT_TYPE_UINT64).
A GVariant of type SR_T_MQLIST can thus always represent more than
one MQ/MQflag pair.
The tables defined with this struct can now be used for information
on items other than config keys.
Functions to access these tables have been renamed sr_key_info_[name_]get.
These take an extra argument, keytype, which should be set to SR_KEY_CONFIG
to get the config key tables. Other key types will be added.
Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong. Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.
Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself. This matches the convention
already imposed on users of the library.
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 makes 'output_frequency' symmetrical with 'output_current' and
'output_voltage'. On a more fundamental level, there's no reason why
frequency should be treated as a discrete quantity, other than
"es51919 used it this way".
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.

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.

Use g_malloc0() for small allocations and assume they always
succeed. Simplify error handling in a few places accordingly.
Don't always sanity-check parameters for non-public (SR_PRIV)
functions, we require the developers to invoke them correctly.
This allows further error handling simplifications.
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.
