Add output styles to gdb
This adds some output styling to the CLI. A style is currently a foreground color, a background color, and an intensity (dim or bold). (This list could be expanded depending on terminal capabilities.) A style can be applied while printing. For ui-out, this is done by passing the style constant as an argument. For low-level cases, fprintf_styled and fputs_styled are provided. Users can control the style via a number of new set/show commands. In the interest of not typing many nearly-identical documentation strings, I automated this. On the down side, this is not very i18n-friendly. I've chose some default colors to use. I think it would be good to enable this by default, so that when users start the new gdb, they will see the new feature. Stylizing is done if TERM is set and is not "dumb". This could be improved when the TUI is available by using the curses has_colors call. That is, the lowest layer could call this without committing to using curses everywhere; see my other patch for TUI colorizing. I considered adding a new "set_style" method to ui_file. However, because the implementation had to interact with the pager code, I didn't take this approach. But, one idea might be to put the isatty check there and then have it defer to the lower layers. gdb/ChangeLog 2018-12-28 Tom Tromey <tom@tromey.com> * utils.h (set_output_style, fprintf_styled) (fputs_styled): Declare. * utils.c (applied_style, desired_style): New globals.
