Some locales (e.g. fr_FR.UTF-8 on ArchLinux) don't split the string stream on a space. As such, when extracted formatted data from te stream, it will return the two numbers as one for the first call, effectively overflowing the u32 variable, then will do an out-of-bounds read for the second call. Forcing the use of the C locale on the streams where it would cause a problem allows to workaround this behavior.
g_compressAndDumpStateSyncEvent was Set() before destruction of file object (i.e. before flushing changes and closing file).
Also, adds Common::ScopeGuard wrapper for RAII.
Added 3 depth/convergence presets. They are adjustable via (existing) hotkeys - changes to depth and convergence are applied to current preset.
Added 3 hotkeys for activating presets. Added hotkey for toggle between first and second preset.
Added OSD message for convergence/depth changes.
Presets are saved into per-game configs.
