For platforms which do not support threads (i.e. emuscripten), queue->thread might not have any work_thread_info's added to it. This is bad as osd_work_item_queue_multiple will access queue->thread[0] when queue->threads == 0, and subsequently crash as the queue has no items in it.
Also Fixed AY8913 chip select routine that relied on the wrong PIA and improved save state support.

- Perform signed calculations for /, %, >>, /=, %=, >>=, <, >, <=, >= operators in debugger expressions
- Eliminate workarounds in debugger printf method for system printf not reliably handling 64-bit integers (a previous refactoring adopted strformat for this)
- Output signed decimals for %d in debugger printf formats; also add %u format
- Add two-argument sext function to debugger
* mame/namcos22.h: Use common helpers for integer manipulation, more
appropriate use of inline/static/constexpr.
* bus/gio64/newport.cpp: Changed a couple instances of K&R formatting
that snuck in to Allman like the rest of the file.
* bus/gameboy/gbxfile.h: Added comment about another use of GBX footer
"extra data".
- Make color palette to be b&w for the time being, being more visible to the eye than the previous washed out attempt;
- mask sprite area against defined playfield clip rectangle;
- fix global sprite Y positions, they mostly follow up current scroll value except for some edge cases;
- attempt to fix sprite priorities;
- make tilemap bank more logical (?) bitwise;
In REX3, iterator setup should be a dedicated operation that
is only execuated if
a). A Draw command is execuated with DoSetup at DRAWMODE0 set
or
b). A host write is issued to SETUP register
At setup stage REX3 will calcuate quadrant for a block or span
drawcall or octant together with some Bresenham parameters for
a line drawcall.
Linux newport_con driver is rely on this behavior to use quadrant
calculated by previous draw call to render characters.
