when "extra raw" output is needed.
Use putcom() and comprintf() instead of rputs() and rprintf() for ANSI escape
sequences. This doesn't actually fix any problem, but since rputs() is
"less raw" than it used to be, let's use direct-output routines instead, for
ANSI output.

- for PETSCII, this is automatic and you don't lose blink, but you do lose
  colored foreground when enabling a bright background ("reverse video")
- for ANSI, this mode is typically referred to as "iCE colors" and disables
  blinking-text support
- Ctrl-AE (^AE) is the new attribute code to enable bright-background
  (will have no effect on ANSI terminals that are not iCE color enabled)
  "E" is now valid in the ctrl/attr.cfg file and string values for JS
  console.attributes assignments, as well
- Ctrl-AI (^AI) - blink - now does nothing for ANSI/ICE color terminals
  (blinking is not supported in combination with bright-background)
- Using a new/non-standard CGA attribute bit-flag to indicate the selection of
  bright-background colors (BG_BRIGHT, bit 10), separate from BLINK.
  This change required all/most char/uchar attribute representations to be
  converted to int/uint.

New text.dat strings:
- PetTerminalDetected (renamed from PetTermDetected)
- PetTerminalQ
- TerminalAutoDetect
- TerminalColumns
- TerminalRows
- TerminalMonochrome
- TerminalColor
- TerminalIceColor
- IceColorTerminalQ
This also moved the MsgCarbonCopyList definition to the end of the file
for now.

PETSCII reverse-video attribute fix:
When a CR is sent to the terminal, the reverse-video attibute is auto-disabled
so update our "current attribute" (curatr) value to match the remote.

Support new printfile/putmsg mode flag: P_WRAP to force an ungraceful
line-wrap (splitting) to the specified column width. If no column width is
specified (0), then this mode will force an ungraceful wrap before the last
terminal column where some terminals *may* auto-wrap.

JS console.printfile() and printtail() methods now support an optional
"orig_columns" argument, similar to console.putmsg(). Must specify P_WORDWRAP
or P_WRAP for this argument to have any effect.

Much improved terminal-type selection/configuration in the user defaults
menu and abort (^C) at any of the yes/no prompts is now detected/handled much
better (to answers to the prompted questions are not saved to the user
settings).

argument and buffer and retruns an optimized ANSI sequence to generate
the desired attribute.
console.ansi() method now support this usage as well, so msgutils.js's
attr_to_ansi() should no longer be needed.

Had the row/col sane-range checking reversed.

place to do it, but may need some special handling for HTMLterm mode.
Parse columns from ANSI cursor position reports.
Request Telnet "Negotiate Window Size" option during answer since this is more
reliable than ANSI cursor position reporting (especially with terminals that
wrap cursor positioning requests).
Improve validation of ANSI cursor position reports.

ansi_restore() in place of dumb macros that don't check the current terminal
support.

expecting an ANSI cursor position report and we will use this value to
determine the user's screen dimensions (currently, lines only).

by properly const-ifying the appropriate functions and variables.

Added special values for ansi() to return escape sequence for normal and black background.
