Since James' recent FG work, the Qt private headers are not needed
anymore for the Qt launcher; clarify this in the comments (they are
still needed for FGQCANVAS, but it is disabled by default).
This will enable richer author meta-data in aircraft, and hence
nicer GUI presentation of author information. Client-side support
still to be added before this can be used
The qml-module-qtquick-dialogs package is needed for the built-in
launcher's Settings dialog since FlightGear commit
37dc418ce1978a55281cdedf6983e0e3ffea0108.
Forum user daweed reported[1] a nasty error[2] when doing 'git clone' or
'git pull' for FGData with the HTTPS protocol. This error disappeared as
soon as he replaced libcurl4-gnutls-dev with libcurl4-openssl-dev on his
system.
-> favor installation of libcurl4-openssl-dev over libcurl4-gnutls-dev

was non-properly terminated"
Re-add the old feature, that -set.xml files can explicitly opt-out of
being included in the catalog. Useful for some development and helper /
included files in some aircraft.
Typical output of:
dpkg-query --showformat='${Status}\n' --show dctrl-tools
is:
install ok installed
(three words, not one). Thanks to wkitty42 for the report.
Rely on CMake install (in FlightGear) to copy all the required libs
to bin, so we simply grab them as part of that, instead of taking
them from the redist folder.
This relies on a corresponding FLightgear change.
Declare qtdeclarative5-private-dev and qml-module-qtquick2 as optional
dependencies, because they are needed for the built-in launcher,
starting from FG commit 3a8d3506d651b770e3173841a034e6203528f465
(committed to FG on 2017-09-26). People who can't install these packages
(oldish systems, etc.) should still be able to build and run FlightGear,
but without the built-in launcher.

- Rename _package_alternative_inner() to _find_package_alternative() and
modify it to make it more useful when called from other functions. If
a package is found that matches one of the alternatives, its name is
printed on stdout, otherwise nothing is printed (empty output).
- Adapt _package_alternative() accordingly and rename it
to _mandatory_pkg_alternative().
- New function _optional_pkg_alternative() based on
_find_package_alternative(). Contrary to _mandatory_pkg_alternative(),
if no match is found in _optional_pkg_alternative(), a message is
printed to stdout but the script doesn't abort.
