The Tecpel DMM-8060 was added since we assumed it would be a rebadged
Voltcraft VC-820 (since we know the Tecpel DMM-8061 is a rebadged VC-840).
However, according to the vendor webpage it doesn't have PC connectivity
at all, so drop it for now (until someone can confirm that it does or does
not actually have RS232/USB connectivity).
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.
Implement SR_HWCAP_LIMIT_MSEC capability, to allow acquisition to automatically
stop after a specified amount of time.

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!)
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.
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.

Store/use the receive_data() function and a pointer to the driver struct
in the dmms[] array. Use a ".subdriver" entry in the driver struct.
Use a macro to simplify hw_init() wrappers.
Declare dmm_info dmms as extern in protocol.h to prevent duplicate
symbol error from the linker.

Use the infrastructure of serial-dmm to handle the RadioShack 22-812,
and completely remove radioshack-dmm.
