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.

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.

Uwe Hermann 1476661970 serial-dmm: Rename VOLTCRAFT_VC820 to VOLTCRAFT_VC820_SER.
This matches the _ser suffix of the other functions/variables for this
device ("ser" denotes that it is used with the serial UNI-T UT-D02 cable
as opposed the USB/HID based cables which are handled by the uni-t-dmm driver).

But more importantly, the _SER suffix for the enum value will prevent
name clashes later, when the uni-t-dmm driver gets a VOLTCRAFT_VC820 enum.

Do the same for VOLTCRAFT_VC840.

Uwe Hermann 35e199da50 Fix limit_samples check in various drivers.
Check whether a sample limit was actually set (> 0) before checking if
that sample limit is reached. This also fixes continuous acquisition mode
for drivers which have that.

Alexandru Gagniuc d55c89f523 serial-dmm: Properly handle continuous mode
serial-dmm does not check if a sample limit is actually in place before deciding
to stop acquisition. Since the sample limit is set at 0 by default, operating
in continuous mode will cause acquisition to stop before even sending the first
sample.

Check to make sure we actually are in a sample-limited mode before stopping for
this reason.

Uwe Hermann 54d1122187 serial-dmm: Add Voltcraft VC-840 (UT-D02) support.
This works with the UNI-T UT-D02 (RS232) cable. For the USB/HID
based cable (UNI-T UT-D04), the uni-t-dmm driver must be used.

Note: This is untested, but should work just fine for all settings, with
the possible exception of temperature (testers needed!)

Uwe Hermann 16b7b79005 serial-dmm: Eliminate unneeded "subdriver" field.
Just use the 'int dmm' + wrapper method that is used for all other
functions which need this information. There is no real need to
special-case the hw_dev_acquisition_start() API call here.

Alexandru Gagniuc e7ed87a469 serial-dmm: Use dummy info struct for rs9lcd parser
The rs9lcd parser, which is used for the RadioShack 22-812 does not use its
*info parameter, and therefore did not have a rs9lcd_info struct declared.

With recent re-factoring of the receive data callbacks, it became necessary to
pass a struct pointer. This made the RECV_DATA macro look like:

- RECV_DATA(RADIOSHACK_22_812, metex14)

giving the wrong impression that the RadioShack 22-182 uses the
metex14 protocol, which is not the case.

Create a dummy rs9lcd_info struct, and correctly identify the parser
as rs9lcd in the RECV_DATA macro:

+ RECV_DATA(RADIOSHACK_22_812, rs9lcd)

Alexandru Gagniuc c69049091e libsigrok.h: Don't store subdriver in sr_dev_driver
Not all drivers use subdrivers. The only reason the subdriver field was
introduced was to accomodate the model of serial-dmm.

The sr_dev_driver struct is available to the frontend. Exposing the subdriver
field creates the problem of exposing knowledge of libsigrok's internal driver
layout, even though the drivers are designed to be a flat list to the frontend.

Store the subdriver in the dev_context struct of serial-dmm.

Alexandru Gagniuc d128bf12b2 serial-dmm: Remove global sr_dev_driver *di alias
The global *di alias was used to keep track of the driver context.
It caused issues with trying to use several subdrivers at once, so
its use was obsoleted.

The correct context is preserved through different mechanisms, either
the *sdi pointer, or wrappers which pass the correct context.

The *di alias is no longer used, so remove it.

Alexandru Gagniuc 3098b3902d serial-dmm: Simplify wrapper layout
Wrappers for hw_init, hw_cleanup, clear_instances, and hw_scan are needed for
each subdriver due to the nature of serial-dmm. These wrappers are implemented
as macros, in order to reduce the number of lines of code.

For each of those functions, we have a separate wrapper list, then we connect
them together in a first-class driver using a DRV macro, and yet another list
(the DRV list).

Instead of declaring those wrappers in separate lists, include them in the DRV
macro. This approach reduces the number of macro lists from five to just one.

From the perspective of adding a new subdriver, this also greatly reduces the
number of places needed to hook in a new device.
