Win32: Set the minimum size of the PPSSPP window to exactly 1x.

Makes it convenient to set 1x, and smaller sizes don't really make

becoming 0, which might be an issue with buggy drivers.
Don't override WM_PAINT like that, weird effect ensued (popup menus broke)
Improve some error messages
Typo fix
Oops
Remove some redundancy (Symbian/Qt). Symbian has cstdint now.

Don't eat extra cycles when idling.

Rescheduling between threads takes about 3000 cycles, but that's not true
for both sides of e.g. a delay.
