Bert Vermeulen 1987b8d63e drivers: use new sr_config struct
Sending an SR_DF_META packet at the start of every stream is not
mandatory; the frontend should ask for what it needs, and any extra
information the driver wants to send will come in due time.

Uwe Hermann 5edc02c77c Add missing "ULL" suffixes.
These numbers are larger than 32bit, mark them as ULL to avoid compile
failures on 32bit systems.

Bert Vermeulen 6b8d6f93bb Get rid of obsolete SR_DI_NUM_PROBES and SR_DI_PROBE_NAMES.
Frontends should use the probe list in the device's sr_dev_inst
to get this information.

Also, NULL-terminate all of them.

Uwe Hermann dc890b8f9f asix-sigma: Quickfix for an ASIX SIGMA issue.
It's not entirely clear whether this is the right fix, but we're merging
it for now, pending later review.

Uwe Hermann a873c5940c Consistently use 'di' as variable name.
Use 'di' consistently in all drivers as the name for a local, static
pointer to the respective driver's 'struct sr_dev_driver'.

Bert Vermeulen 69b07d14db allow for intermediate stage in stopping acquisition
In the case of USB drivers, a driver's dev_acquisition_stop() cannot
simply remove its fd sources from the session and close its devices:
a USB transfer might still be underway, and it needs to be finished
(and its memory freed) properly.

An sr_dev_inst->status value is added: SR_ST_STOPPING, which should
be set when the driver's dev_acquisition_stop() is called, and acts
as a marker for the USB event handler to wind up its operations.

In order for dev_acquisition_stop() to be able to set the sdi status,
however, it needs to be unconstified.

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.

Bert Vermeulen 014359e329 sr/drivers: obsolete SR_HWCAP_PROBECONFIG
Since probes now live in a struct sr_dev_inst owned by the driver, it
already knows about them. Instead of a frontend telling the driver to
configure probes, all driver now do this just before starting acquisition.

Bert Vermeulen 9e90dcba9c sr/drivers: remove driver API call dev_status_get()
It's obsolete: no frontend ever used it, and neither did libsigrok.
The sdi->status field is only used internally by some drivers, and
should probably be moved to the driver-specific context structs.

Bert Vermeulen 61136ea603 sr: add new driver API call: scan()
This changes the semantics of the init() call as well. That now only
initializes the driver -- an administrative affair, no hardware gets
touched during this call. It returns a standard SR_OK or SR_ERR* code.

The scan() call does a discovery run for devices it knows, and returns
the number found. It can be called at any time.

Bert Vermeulen 40dda2c3a5 sr: remove unused argument from hardware driver function init()
It was actually used in one way: the session file loaded abused it for
passing in the filename -- something it definitely wasn't intended for.
This now uses the proper way to pass arguments to a driver: the new
SR_HWCAP_SESSIONFILE.

The OLS driver could also use it as an indication of the serial port to
use instead of actively probing all serial ports on the system, but there
wasn't any frontend code that passed in such a parameter, making it
entirely useless. That will soon be handled differently with the new
scan() API call, regardless.

Bert Vermeulen 45c59c8bdd sr: moved sigrok.h so libsigrok/libsigrok.h
All frontends will have to include <libsigrok/libsigrok.h> from now on.
This header includes proto.h and version.h, both installed from the
distribution into $INCLUDE/libsigrok/ as well.

The only dynamically changed header is now version.h, which has both
libsigrok and libtool compile-time versions in it.
