Fixed _textcolor definition. 
The _textcolor() macro doesn't just turn on the macro optimization. It defines the return value of textcolor() - and that is supposed to be a COLOR_... value.

2617e9a3c0 Added a C header that translates from the source file's encoding to PetSCII. 
It can be used to undo what "cbm_screen_charmap.h" does.  Together, those headers let you mix screen-code and PetSCII string and character literals in a C source file's Assembly output.

7e298e347d Fixed the CBM screen-code C header. 
Changed the number literals from Assembly format to C format.  Swapped the (upper-/lower-case) mappings of letters because the header converts from ASCII, not PetSCII.

417ef278a3 Move Atari-specific PIA reg vals to atari.h 
PIA is also used in the Commodore PET, and for different
purposes (see http://www.6502.org/users/andre/petindex/progmod.html#pia1),
so extracted Atari-specific register #defines and placed them in atari.h.

9a83284b7b Cleaned up _pia.h register stuff a bit 
Most documentation say that most of the bits are normally set to 1 or 0,
so just mentioning that in the comments.

A.N.A.L.O.G. issue 59 (April 1988) "Bits & Pieces" column, "Atari Zucchini"
(https://www.atarimagazines.com/analog/issue59/bits_pieces.php) implies
that they are used for specific things, but it's not clear enough to be
useful (or specifically states "Too complex and not pertinent").

This is probably sufficient for most purposes; if any PIA / PACTL/PBCTL
experts pop up, they can tell us exactly how those 4 bits can be utilized.

af8eb57f63 Atari colors into _gtia.h; NMIRES/NMIST as union 
Use a C "union" to give both read (NMIST) and write (NMIRES) labels
to their shared register in ANTIC. (h/t @groessler).

Consolodate duplicated color definitions (HUE_..., COLOR_... and TGI_COLOR_...;
and the "_gtia_mkcolor()" macro), found in both "atari.h" and "atari5200.h",
moving it to "_gtia.h", which they both share (and which makes the most sense).

93a13315de Comment adjustments; removed surperfluous keycodes 
Cleaned up comments in Atari 8-bit headers.
Internal keycodes (POKEY's KBCODE) were already #defined in atari.h,
so didn't need a whole new set in _pokey.h.

4b61c54092 Relocate register values outside structs, + more 
Relocated register #define'd values outside of the structs,
improved comment format, expanded & corrected some things.

register descriptions.
