Floats can lead to calculation errors because, now uints are used and aspect ratio values are handled with a x 10000 scale.
When entering fullscreen, it will be looked for the fullscreen mode with the smallest metric that mantains the game screen aspect ratio.

Found that the particular implementation was producing messy assembly for misaligned copies. Improved it and also fixed up wrapping the memcpy, which would cause endless prints in case memcpy testing is asked for.

OSystem_SDL will create a merged list of all graphics modes from SDL and OpenGL. When the user changes the graphics mode in options and restarts ScummVM should switch to that graphics mode in the corresponding graphics manager.

This fixes a hack for resetting the graphics scale to x1 when starting games that have a large screen size. The SDL graphics manager should now scale back to x1 without changing the current scaler in use, as well as the OpenGL graphics manager.

If a game CD has a scummvm.ini file with at least one game domain in
it, the normal autodetection is now bypassed and a menu of only the
games in the .ini file is presented instead. The descriptions of the
games are taken from the .ini file, but icons are still scanned for
in the old fashion.
Note that previously ScummVM would read global options from the
scummvm.ini file on the boot disc (if present), but now global options
are instead taken from the scummvm.ini on the game disc (in case of
a disc swap).

Implement platform-specific variants of createConfigReadStream()
and createConfigWriteStream(), instead of inheriting the BaseBackend
definitions. Nonstandard behavious is as follows:
* createConfigWriteStream() always returns 0 (read-only filesystem)
* createConfigReadStream() returns an empty MemoryReadStream instead
of NULL if scummvm.ini does not exist. This is to make sure that
loadDefaultConfigFile() always clears out any old config data, as
I'll want to restart config parsing from scratch after a disc
swap.

This should help avoid situations where MODULE_DIRS is not set to a
complete list of build dirs (which causes troubles with the automatic
header dependency detection logic).
On the long run, we should replace the relevant code by a macro or also
use rules.mk for this (with yet another if/else case add to it).
