Rationale:
1. Now to reset a CVAR to default, the user doesn't need to remember the default value.
2. If a modder wants to reset a CVAR via menu command, they don't need to keep menudef and cvarinfo in sync.
src/common/filesystem/file_ssi.cpp:78:20: warning: comparison of integers of different signs: 'int' and 'uint32_t' (aka 'unsigned int') [-Wsign-compare]

This allows proper dimensions in the stock menus and should make menu layout for mods a lot easier because coordinates are more predictable than with the clean factors.
The feature is opt-in for custom content. As long as only stock elements are used, the menu will be able to switch between both on its own, but as soon as custom classes or custom elements are used, the virtual size must be declared explicitly, defaulting to clean scaling.
In this mode the clean scaling factors are ignored and content is always scaled to fit the screen as efficently as possible.
For the default summary screens an option was added to use this mode, which is a lot closer to the original look of this screen.
It is not 100% identical because it still factors in the author, if given and long level names that may be broken into multiple lines of text.
Sensitivity scaling of both axes is now exposed as a raw factor to the user instead of obscuring it behind an unclear 'prescale' boolean.
This also consolidates the coordinate processing code to prevent such discrepancies as were present here from happening again.
Migration code for old config settings is present so that this change does not affect existing configurations.
- DirectInput axes are now X first, Y second.
- Menu axes controls swapped/fixed.
- Added SDL DualShock3 buttons in menu actions.
- Fixed SDL mouse system cursor; it could appear in-game.
* support for SSI container format - this is an obscure format used by a few Duke Nukem mods - added to have this subsystem identical between both engines.
* removed some dead wrapper code
* made the Open methods local to their implementations, this was never called virtually.
* new texture format: ANM - this reads the first frame of a Build-ANM movie as a texture.
* some preparations for indexed (paletted) rendering.
* optimization of the patch texture checker - do not read in the entire file if checking the initial header is sufficient for rejecting it.
* removed refreshFreq variable and related code. This only got into the backend because of stupid interpolation code in some of the Build games which has long been removed.
* save FixedBitArrays as base64 in savegames.
* allow indirections in the string table - by prefixing the language string with '$$' the remaining text is interpreted as another string label to resolve.
* constexpr in palette code, also replacing #defines with enums.
Backported from Raze - without this there is no way to implement sounds that can unload themselves, because the existing ChannelEnded function is called when the sound is still active.
