Uwe Hermann 53b4680fce Consistently use 'cg' for channel group variables.
This matches how we consistently use sdi, devc, and so on all over
the code-base.

This fixes parts of bug #259.

Uwe Hermann 660e398fe9 Replace 'probe group' with 'channel group' everywhere.
The name 'probe' (and thus 'probe group') is a relic from the times when
sigrok was mostly about logic analyzers. Nowadays we support a lot more
device types where 'probe' is not really a good term and 'channel' is
much better suited.

This fixes parts of bug #259.

Daniel Elstner 2a854d7139 hwdriver: Introduce sr_config_commit() API call.
(sr_dev_driver.config_probe_set): New optional callback enabling
drivers to be notified upon changes to probe settings.
(sr_dev_probe_enable, sr_dev_trigger_set): Invoke new driver
callback on changes.
(sr_dev_driver.config_commit): New optional callback allowing
drivers to defer application of configuration settings until
an explicit call to config_commit().
(sr_config_commit): New public wrapper function.

Bert Vermeulen a769b9f357 Add sr_session_save_init().
This allows a frontend to initialize a session file, providing the
required samplerate and probe names, without having a proper
struct sr_dev_inst handy.

sr_session_append() is then used to add captured data to the session
file, as usual.

The existing sr_session_save() function works the same way as always.

poljar (Damir Jelić) 9e4f8cf93b strutil: Add helper functions: string to number.
This patch adds helper functions for converting a string to different number
formats (double, long, float, int).

These functions are exposed in the public API.

Bert Vermeulen f438e0c923 Add sr_session_append(): add captured data to an existing session file
This extends the session file format to contain logic data files named
either "logic-1" as before, or "logic-1-1", "logic-1-2", ...
representing chronologically ordered chunks of captured data.

The chunks are transparently concatenated together by sr_session_load().

Bert Vermeulen bc1c2f001a Use GVariant for sr_config_*() functions
sr_config_get() provides a GVariant owned by the caller, so it must be
released with g_variant_unref() when done.

sr_config_set() takes a GVariant from the caller which may be floating;
it will be properly sunk and release after use by this function. Thus
the output of g_variant_new_*() may be used as an argument.

sr_config_list() also provides a GVariant owned by the caller, to be
unreferenced when done.

sr_config_make() can take a floating reference.

Uwe Hermann a819da9c25 Drop deprecated sr_session_halt().
This has been deprecated in favor of sr_session_stop() since a while.

None of the current frontends use sr_session_halt() anymore, neither
does libsigrok.

Bert Vermeulen c5fb502f97 New driver API function: config_list()
This takes an sr_config key and returns a list of possible values for
that key to be submitted with config_set(). The format of the list and
its contents is dependent on the key.

This will replace the SR_DI_* keys that returned such a list before,
such as SR_DI_SAMPLERATES.

Joel Holdsworth bf53457d1d Pass sr_datafeed_packets and payloads with const pointers
This patch marks packet structures and their payloads as const.
This indicates to packet receivers that modifications to these are
not allowed. In general all pointers should be marked const unless
modification of the referenced data is explicitly allowed.

Bert Vermeulen 811deee4af sr/drivers: add API calls sr_dev_inst_list() and sr_dev_inst_clear()
These are used to list the device instances currently known to the driver,
and clear that list.

Drivers that don't necessarily clear their list of instances on every scan,
such as genericdmm, need to provide these to the frontend to keep instance
management sane.

driver and device struct sr_hwcap_option arrays were published.
