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).
So far, it seems we can make this work with just hw_init() needing to
be subdriver-specific (it will point 'di' to the respective per-subdriver
entry), the rest of the API functions can then use a strcmp() on di->name to
learn which subdriver they belong to.
The 'uni-t-dmm' driver/directory will not appear as a "driver" to
frontends anymore, it's just an internal thing.
The frontends will see a uni-t-ut61d and voltcraft-vc820 driver now,
with the correct names and parsers etc. attached to them.
This is not fully finished yet, but it's a start (and works mostly):
$ sigrok-cli -D
The following devices were found:
UNI-T UT61D with 1 probe: P1
Voltcraft VC-820 with 1 probe: P1
$ sigrok-cli --driver voltcraft-vc820 -D
The following devices were found:
Voltcraft VC-820 with 1 probe: P1
$ sigrok-cli --driver uni-t-ut61d -D
The following devices were found:
UNI-T UT61D with 1 probe: P1
