The new function logstream::setTestingMode() has been created to allow for a
testing mode to be set. This stores a boolean in the private logstream thread
which modifies the behaviour of the would_log() function, allowing for
everything to be logged. The removeCallbacks() function has also been added,
allowing for the default fgfs output to STDOUT and STDERR to be silenced when
calling setTestingMode().
Add test coverage for disabling a catalog due to version, and also
for auto-migrating to a new version. Expose disabled catalogs on the
Root, so they can be checked for.
Since the dawn of times (FG commit
1bcaf4bfdd38f18ac7c375dd9319935ff3df56ac, where SGBinding was called
FGBinding), SGBinding's destructor has had a strange behavior:
SGBinding::~SGBinding()
{
if(_arg && _arg->getParent())
_arg->getParent()->removeChild(_arg->getName(), _arg->getIndex());
}
In other words, it used to remove the passed-in <binding> node from its
parent node (if any) once the SGBinding instance got destroyed. This
behavior is very unintuitive to several people and has resulted in a few
workarounds in the FG code base just to cope with this strangeness.
This commit gives SGBinding the implictly-generated destructor,
therefore SGBinding::~SGBinding() does not attempt to remove the
property node anymore.

this is to use some kind of utc time for timestamps in mp protocol,
to improve the lag correction system for mp planes, using a
"real time" mode when possible.
Remove an apparently bogus portability workaround (which was presumably
targetting one of the bugs fixed in the previous commit [1]) and further
simplify the code using std::find().

Explicitly enable the CMP0067 policy to have try_compile use the correct
C/C++ standard flags; otherwise, CMake will default to not honoring those,
causing the C/C++ checks to be compiled with no standard flags and SimGear
to be compiled with them. This causes errors if we try to detect a new
prototype which is only present in C++14 and above).
