Apparently, glibc uses an overly aggressive caching strategy, causing
Creator to accumulate an unreasonable amount of resident memory over
time.
We deal with this by manually forcing glibc to free unused memory once a
minute, provided the application is actually in use.

LD_PRELOAD is useful e.g. to preload custom malloc implementations
for profiling purposes. At times, it makes sense to not propagate
that to spawned child processes. This here allows to prevent that
by setting another variable, QTC_DO_NOT_PROPAGATE_LD_PRELOAD, in
the environment.

At startup check if there is a plugin for which we wrote, but not

We used to set QT_OPENGL, currently set LD_LIBRARY_PATH when qtcreator.sh
is used, and might set other variables in the future,
but these environment modifications should not be passed on
to user applications or when we run tools that are not shipped with
Qt Creator.
For LD_LIBRARY_PATH there already was a hack for
Environment::systemEnvironment.
For environment variables that we might set in main()
in the future, this patch caches the system environment for
Environment::systemEnvironment early before any modifications are made.
The previous hack for LD_LIBRARY_PATH no longer works, since it
used QCoreApplication::applicationDirPath() which cannot be used at that
point in time (before the QApplication has been created). Instead pass
the correct user LD_LIBRARY_PATH directly from qtcreator.sh to
Qt Creator through a command line option, which is cleaner anyhow.
