Fix warning

Works-around #5396

This is no longer necessary now, when the omxil module keeps
track of the number of initializations of the OMX Core.

This avoids deinitializing the global OMX Core if a second
instance of the module is initialized (e.g. for testing whether
it can handle decoding another stream) and deinitialized while
the first instance still is active.

This should fix a regression on non-FPU builds whereby the built-in
downmix of some decoders was not used anymore.

add_deprecated_alias does not work at all, so lets avoid it. Anyway,
the remaining affected configuration items are not very commonly used.
This works around #5266.

Exceptions:
 - decklink and shm new plugins in VLC 1.2,
 - imem not usable through VLC directly,
 - rtmp never compiled in VLC 1.1 (and VLC 1.2).

This should fix the warning about 8 not being a valid control type.

This changes the path added in
17c3d301 to the right one.

Doing the white balance is an action, showing as a "void" variable
in VLC and button control in V4L2. So it made no sense to have an
integer configuration item for it.

They were deprecated in Linux version 2.6.26.

Ideally, we should subclass QAbstractSpinBox to support 64-bits values.
But in the mean time, lets at least support the int32_t range.

Otherwise, the caller cannot determine that the value is not defined,
such that the vlc_value_t is not set and cannot be used.
