...
The `SubOpcode31Grabber[1024] = { ppc_illegalop }` initializer only
populates the first entry with ppc_illegalop (at least on some compilers),
switch to explicitly initializing the entire array with std::fill_n.
Also fix a couple of sign and overflow issues flagged by the Xcode
undefined behavior sanitizer.

Inline ppc_set_cur_instruction

It's used in the main emulator loop (ppc_exec_inner), and the function
call overhead adds up.
By inlining it, time to boot to the Finder using a 7.1.2 install CD
and a 6100 ROM goes from ~6700ms to ~6400ms (with clang 14 on a

Fix emulation of doz, dozi, and nabs POWER instructions
...
doz and dozi were storing the result into the wrong register.
nabs was not taking into account two's complement storage of numbers
and was just setting the signed bit.
These two instructions are used in the implementation of text
measurement in native QuickDraw on 7.1.2/the PDM ROM, and the incorrect
values were resulting in nothing being rendered. With the fix text
appears when booting from the 7.1.2 CD.

Fix keyboard events occasionally being dropped
...
AdbKeyboard would copy the event into its own fields and set the
changed field, so that we could return the event when register was 0.
However, if a subsequent event was received before ADB polling, the
previous event would be overwritten and lost.
Fix this by maintaining a queue of events, so that we can return
everything since the last poll.

Fix "a" key always being as as a keyup
...
We were using an empty value on the second byte of the ADB keyboard
register 0, but that maps to the "a" key. This manifested itself
as the Key Caps DA never showing the "a" key as being down.
Switch to a non-existent key for the second byte.
