This suggests that the timer is reset when start() is called even

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.

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

aren't overlapping with it.

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.

This change addresses bug #1199.
