In NixOS@3fafb02
the Qt version used by Qutebrowser was downgraded from 5.15 to 5.14.
Let's be consistent by also setting qt514 and including a comment so one
can trace why it is used.

(Note that downgrade gave it the same Qt version as used by the Python
packages set at the time, so in principle the override could be
removed.)

(cherry picked from commit 4bccbd9)

Since we now use qt5.15 in all python modules (defaulting to the same
qt5 used in all-packages.nix), That patch is not required, but it will
be needed if qt5.14 is used if pythonInterpreters is overridden, which
is likely to happen like it happend to qutebrowser for instance. See:
NixOS@2667af4

Bonus: Set `makeWrapperArgs` instead of calling `wrapQtApp` - to prevent
double wrapping.

(cherry picked from commit 198e025)

(cherry picked from commit 5cbf0c1)

Since now Python packages use qt5.15, this should too.

(cherry picked from commit f3e5c93)

Remove included upstream patches. Use qt5.15 (NixOS#99956). Spare double
wrapping by using `makeWrapperArgs+=()`.

(cherry picked from commit 2edd4ed)

(cherry picked from commit cd5b560)

Add an optional withGui flag to turn off gui as most of the time it's
not needed since this is a python library.

Use a GitHub tarball to optionally enable tests, currently disabled by
default, but next release' tests should pass (tested the beta release
tag).

Wrap qt apps properly, without double wrapping, if gui is enabled.

(cherry picked from commit 36b7e89)

Since Python's pyqt5 is using qt5.15, it should use the same version as
well.

(cherry picked from commit 56d047f)

The same as used by pyqt5 (NixOS#99956).

Also: Fix double wrapping.
(cherry picked from commit bc0113e)

Don't mix qt5.14 and pyqt5 which uses qt5.15 (NixOS#99956).

(cherry picked from commit 16c2b3c)

Bonus: Spare double wrapping.
(cherry picked from commit 3d8267e)

Don't double wrap executables.

(cherry picked from commit 62738d4)

Wrap application with wrapQtAppsHook and no double wrapping.

For security reasons [1] we upgrade to the latest Qt, despite this
breaking a feature, which is why 5.14 was forced earlier.

(cherry picked from commit c0d5cf4)

Update many dependencies. Add a patch that fixes a build. Use
`libsForQt5` instead of `libsForQt514`.

They do depend on qt5, and putting them in top level scope could cause
qt5 incompatibilities errors.
