Core options handling changes

[andres-asm]

I made a few changes that affect core option behavior.
Report any options that do not work here.

Tested options:

Emulated machine

• startup

Memory size

• startup

CPU core

• startup
• in-game

CPU type

• startup
• in-game

Cycles

• startup
• in-game

Blaster

• startup
• in-game
  This is disabled on purpose, changing blaster settings does not update the BLASTER line so it can't be done on the fly

GUS

• startup
• in-game
  This is disabled on purpose, changing blaster settings does not update the BLASTER line so it can't be done on the fly

Speaker

• startup
• in-game
  This can probably be fixed

[andres-asm]

CPU core fixed in 5df9ecf

Joystick toggles fixed in 5df9ecf

PC Speaker can now be toggled on the fly since 5df9ecf

Aspect ratio correction

• startup
• in-game

Joystick timed intervals

• startup
• in-game

Scaler

• startup
• in-game

Gamepad emulated mouse

• in-game

Hercules modes

• startup
• in-game

[andres-asm]

Other than GUS, Tandy and DSS that I don't know how to test, all good

Crashes at startup for me. Both native Linux as well as in Wine.

I've reset the libretro branch back two commits and put them in the core-option-overhaul branch.
