The "-display sdl" option still uses a hand-crafted parser for its parameters since some of them used underscores which is forbidden in QAPI. Now that the problematic parameters have been removed, we can switch to use the QAPI parser instead. This introduces the new "DisplaySDL" QAPI struct that is used to hold the parameters that are unique to the SDL display. The only specific parameter is currently "grab-mod" which is modeled as a string, so that it could be extended for other arbitrary modifiers later more easily.

One step at time. Here's my attempt at a more accurate commit message. The "-display sdl" option still uses a hand-crafted parser for its parameters since we didn't want to drag an interface we considered somewhat flawed into the QAPI schema. Since the flaws are gone now, it's time to QAPIfy. Are the values of @grab-mod parsed in any way, or do we recognize a set of fixed strings? The former would be problematic. We try hard to represent complex data as JSON instead of inventing little ad hoc languages. If it's the latter, use an enum. Makes introspection more useful, and adding enumeration values is no harder than adding string literals.

We have "-sdl" and "-curses", but no "-gtk" and no "-cocoa" ... these old-style options are rather confusing than helpful nowadays. Now that the deprecation period is over, let's remove them, so we get a cleaner interface (where "-display" is the only way to select the user interface).
