removed ambiguous m_file in CachingCodec.h
[rbp] Ensure resolution infos have unique names

Currently the strMode for 2D and 3D resolutions have the same name.
This means the calibration info for a 2D mode can get replaced with a 3D mode
which can result in the pixel aspect ratio being reset to 0.5.

Also when using gui resolution clamping (i.e. 720p gui on 1080p display)
the calibration settings are scaled to gui resolution, but there is no indictation
of what the clamped resolution was when the settings were saved.

This means disabling gui clamping results in a minature gui.
(And I'd like to remove the gui clamping in the future).

Make sure all these resolutions have unique names by adding the gui resolution
and 3DSBS/3DTB to the resolution string.

Note: this will result in current calibration settings being lost.
[ios/atv2] - harmonize the behaviour of builtin "shutdownmenu" - it should behave the same on all platforms now that the shutdownmenu only has usefull entries

Merge pull request #3824 from FernetMenta/aefixes

ActiveAE fixes
changed: function parameter should be passed by reference
removed: the extra qualification 'CSysInfo::' is unnecessary
fixed: the parent class already defines a member variable m_processing but of different type. renamed it to avoid confusion.
removed: member variable already defined in parent class.
changed: rename critsection variable to prevent confusion with the cs variable from the parent class.
changed: use empty() instead of size()
