The resistance values of some DMMs were incorrectly reported due to a
missing factor of 10 in the calculations.
Tested on Voltcraft VC-920/VC-940 and Tenma 72-9380A/72-7730/72-7732.
Bump the number of supported logic channels from 8 to 128. This is
mostly motivated to test the 64 channels limit which some of the
components/subprojects of the sigrok project might have (input/output
modules, user interfaces).
Only automatically enable the first 8 of the 128 total logic channels,
i.e. default to the previous behaviour. Prepare to only enable part of
the set of analog channels, but stick with their being active by default
as well.
Factor out the choice for the default logic pattern, too. This allows
for easier adjustment of the default configuration, when settings are
concentrated in a single spot.
Extend the demo driver, add another waveform choice for logic channels.
Create a "cable squid" logo representation which occupies a large number
of channels.
This pattern occupies 128x128 pixels. Unlike the 'sigrok' pattern it
gets repeated when more channels are involved, but is not shifted in the
repetition.

This fixes bug #700.
This is a (hopefully temporary) workaround for the
SR_CONF_CAPTUREFILE mechanism. The value for
vdev->capturefile is set by this, however only once
via stream_session_data().
During stream processing in stream_session_data(),
capturefile may receive new values - e.g. when there
are multiple logic files or if there is analog data.
With that, the initially set capturefile is overwritten.
When re-loading the file, we are then running into
issues because we don't know what the initial value was.
As all .sr files use "logic-1" by default and, we
simulate the behavior of stream_session_data() and
assign this name to capturefile if there are logic
channels present.
With this change, all three kinds of files reload
as expected: logic only, analog only and mixed signal.
For this reason, it's a short-term fix for #944.
The handling of the digital channels for this series is somewhere
between that of the DS1000D series (PROTOCOL_V2) and the MSO1000Z
(PROTOCOL_V4).
The :LA command set is similar to that of V4, but the LA data has to be
requested with :WAV:SOUR:LA and arrives in interleaved form like V2.
None of these changes should affect other models. They only affect the
case of PROTOCOL_V3 with digital channels, which occurs only for the
MSO2000A series.
'i' was iterating in steps of unitsize. However, the destination array
was also indexed with it, but it is of u8 type. Let 'i' run bytewise and
only multiply with unitsize when we need it.
This fixes parts of bug #844.

Fixes#933.
We'd already had this problem elsewhere and thus have this wrapper function
that does this where necessary. It just wasn't in use on these two call sites,
which was causing timing problems when used over tcp-raw or VXI transports.
With trigger enabled, and with PulseView, a second (or more) acquisition
starts immediately instead of blocking. It's mandatory to try several times
to have a correct behavior.
According to http://mygizmos.org/ols/Logic-Sniffer-FPGA-Spec.pdf section 2.3.1
p.8, the Openbench Logic Sniffer must be reset before each arm command.
This fixes bug #809.

Openbench Logic Sniffer reset is a little more complex than a simple send.
To avoid code duplication, this patch adds a new function dedicated to
this task.

Instead of replacing the group=plugdev, simply add the TAG as well.
This allows (in most cases) the same file to be used happily on systemd
and older group based systems. Some systems may produce warnings about
non-existant groups, but it remains functional. Approach inspired by
that taken by the OpenOCD project.
This fixes parts of bug #665.

Increasing the chunk size from 512ksamples to 4Msamples leads to
slightly faster session file loading from sigrok session (*.sr) files
in frontends, while not looking too "chunky".
The performance increase is not really massive, but still noticeable.
A further increase to, say, 10 or 100Msamples shows no further
noticeable improvements.
This changes the fx2lafw code to only enable the wide_sampling (16bit)
method, if at least one of the higher eight channels is enabled. This
has the benefit, that we can use higher samplerates on 16bit LA
devices if we use only the first eight channels.
The wide sampling is also enabled if we have one or more analog
channels.
