When a meter display 105.2 kΩ, libsigrok will return 105200 Ω
but it is really valuable to know that the last 2 digits are not
significant, so encoding.digits should be set to -2.
This would allow a sigrok client to display 105200 as 105.2 k
instead of 105.200 k.
The method accepts strings with numbers in scientific or normal notation,
e.g. -1.25 or 3.37e-6. The numeric range is limited by the sr_rational
range, i.e +-9.2e18, resolution is ~19 digits.
On the high-end bench multimeters, resistance can be measured with a
kelvin connection as well as the more common two wire method. Provide
a flag which can indicate if four-wire mode is used.
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.
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().

Introduce a new API function sr_session_stopped_callback_set()
which can be used to receive notification when a session stops
running. This allows applications to integrate libsigrok event
processing with their own main loop, instead of blocking in
sr_session_run().
The resource API provides a generic means for accessing resources
that are bundled with sigrok, such as device firmware files. Since
the manner of resource bundling is platform-dependent, users of
libsigrok may override the functions used to open, close and read
a resource. The default implementation accesses resources as files
located in one of the XDG data directories or a directory defined
at compile time.
Completely remove the old session save code that has been
superseded by the srzip output module. Also refactor a bit,
plug a number of leaks and tighten the error checking.
