Fix #1204 by making sure the lazy event handler is fired
The QTimer reference says about QTimer::start():
> Starts or restarts the timer with the timeout specified in interval.
> If the timer is already running, it will be stopped and restarted.
> If singleShot is true, the timer will be activated only once.
This suggests that the timer is reset when start() is called even
when it is in single shot mode. However, this is actually not the case
and start() doesn't appear to be doing anything if it has already
been started. While this works in most cases, it causes issues when
the timer is supposed to be reset and timeout at the specified time
since view items are still in flux.

about: move Pulseview version information into the text box
Move the application's version information out of the caption and into
the text box. So that it resides with the libraries' version information,
and is accessible via clipboard for reports.
This addresses part of bug #1213, and fixes all of #1264.

DecodeSignal: Add and use inclusive/exclusive sample count variant
This is needed because the annotation cache must be operating on the
number of decoded samples WITHOUT the ones being currently processed,
otherwise it'll refuse to refresh the cache, even if more annotations
arrive - it uses the sample count to determine the cache state.
However, the bar showing the undecoded area must operate on the number
of samples WITH the ones being currently processed so that annotations
aren't overlapping with it.
Adding the parameter to DecodeSignal::get_decoded_sample_count() allows
for both.

cmake: help users by pointing out libsigrok build depencendies
It appears that users have trouble to relate failed PulseView builds to
missing dependencies during libsigrok configuration. Although the error
occurs early and is stated in the build output, it only gets noticed
late and users forgot about the earlier step, or never bothered to check.
Explicitly test for the availability of the C++ bindings, and print a
message that points to libsigrok's(!) configuration phase. Another
check for the full set of libraries will fail in fatal ways as before.
An unfortunate implementation detail of the cmake check leaves all parts
of the lookup result empty when either(!) of the tested libs is missing.
So we cannot tell with certainty which test failed when the test result
is negative while a list of libraries was passed to the test. That's why
the "soft" individual test with QUIET and without REQUIRED is the least
intrusive adjustment to existing CMake rules, where other locations
depend on the PKGDEPS_* variables.

after getopt(3) is done. As a byproduct the application code no longer
manipulates a variable that is owned by an external library.

Disable unit tests by default
The rationale for this change is that except for developers, pretty
much everyone who builds from source does so because they want to
use the latest changes. However, only developers care about the results
of the unit tests, so this doubles the build time for users without
any real benefit.
Even worse, the unit tests are known to fail on several hosts for
reasons that are within the realm of the unit tests themselves, not
because of broken code. This confuses users and even prevents them
from installing PV for no good reason.
Since the unit tests do still run on Jenkins, there's little to no
coverage gap in my opinion.
