69731f6642 more IWYU fixes
I'm starting to wonder if IWYU is worth the effort. Nonetheless, this
makes it lint clean on macOS and reduces the number of warnings on
FreeBSD and Linux.

85ba4e0142 Fix colors table (#3826)
* color: make brgrey really grey

The 0055 value is actually 0x2d which isn't 0x55 mentioned further and is probably a typo

* color.cpp: reformat color table

Tidy color table up and also fix hex number case for grey color. This should ease spotting errors like one from previous commit.

3669805627 Improve compatibility with 0-16 color terminals.
Fish assumed that it could use tparm to emit escapes to set colors
as long as the color was under 16 or max_colors from terminfo was 256::

 if (idx < 16 || term256_support_is_native()) {
    // Use tparm to emit color escape
    writembs(tparm(todo, idx);

If a terminal has max_colors = 8, here is what happenened, except
inside fish:

 > env TERM=xterm tput setaf 7 | xxd
   00000000: 1b5b 3337 6d                             .[37m
 > env TERM=xterm tput setaf 9 | xxd
   00000000: 1b5b 3338 6d                             .[39m

The first escape is good, that second escape is not valid.
Bright colors should start at \e[90m:

 > env TERM=xterm-16color tput setaf 9 | xxd
   00000000: 1b5b 3931 6d                             .[91m

This is what caused "white" not to work in #3176 in Terminal.app, and
obviously isn't good for real low-color terminals either.

So we replace the term256_support_is_native(), which just checked if
max_colors is 256 or not, with a function that takes an argument and
checks terminfo for that to see if tparm can handle it. We only use this
test, because otherwise, tparm should be expected to output garbage:

 /// Returns true if we think tparm can handle outputting a color index
 static bool term_supports_color_natively(unsigned int c) { return max_colors >= c; }
...

 if (term_supports_color_natively(idx) {

And if terminfo can't do it, the "forced" escapes no longer use the fancy
format when handling colors under 16, as this is not going to be compatible with
low color terminals. The code before used:

 else {
     char buff[16] = "";
     snprintf(buff, sizeof buff, "\x1b[%d;5;%dm", is_fg ? 38 : 48, idx);

I added an intermediate format for colors 0-15:

 else {
     // We are attempting to bypass the term here. Generate the ANSI escape sequence ourself.
     char buff[16] = "";
     if (idx < 16) {
         snprintf(buff, sizeof buff, "\x1b[%dm", ((idx > 7) ? 82 : 30) + idx + !is_fg * 10);
     } else {
         snprintf(buff, sizeof buff, "\x1b[%d;5;%dm", is_fg ? 38 : 48, idx);
     }

Restores harmony to white, brwhite, brblack, black color names.
We don't want "white" to refer to color color #16, but to the
standard color #8. #16 is "brwhite".

Move comments from output.h to output.cpp

Nuke the config.fish set_color hack for linux VTs.

Sync up our various incomplete color lists and fix all color values.
Colors 0-8 are assumed to be brights - e.g. red was FF0000. Perplexing!

9225b16d12 add (or restore) config.h to all files
The autoconf-generated config.h contains a number of directives which
may alter the behaviour of system headers on certain platforms. Always
include it in every C++ file as the first include.

Closes #2993.

79f342b954 lint cleanup: eliminate "redundant" errors
This removes some pointless parentheses but the primary focus is removing
redundancies like unnecessary "else" clauses.

42068931c7 eliminate "useless parentheses" lint errors
Some `oclint` errors regarding "useless parentheses" are meaningfull. But
the vast majority are bogus in as much as removing the parentheses reduces
readability. So fix a few of the egregious uses and otherwise suppress
that error.

fc44cffac5 restyle switch blocks to match project style
I missed restyling a few "switch" blocks to make them consistent with the rest
of the code base. This fixes that oversight. This should be the final step in
restyling the C++ code to have a consistent style. This also includes a few
trivial cleanups elsewhere.

I also missed restyling the "complete" module when working my way from a to z
so this final change includes restyling that module.

Total lint errors decreased 36%. Cppcheck errors went from 47 to 24. Oclint P2
errors went from 819 to 778. Oclint P3 errors went from 3252 to 1842.

Resolves #2902.

1f06e5f0b9 add better support for IWYU and fix things
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.

dfaefb97ff remove "normal" from the basic color name table
The special token "normal" should not be in the basic sixteen color table
because a) it is not a color, and b) it is special cased with the result of
resetting the terminal colors (usually via a ANSI X3.64 CSI [0m sequence).

0a0acc8a2e add support for ANSI "bright" colors
This adds support for the ANSI x3.64 "bright" colors in the basic sixteen
color palette. This is especially useful when trying to use the base colors
as a background color. The "bright" variants tend to be more useful as
background colors compared to the non-bright variants.

This also fixes a bug in so far as palette number 7 is actually grey and
not white whereas palette number 15 is white. At least on the terminal
emulators on which I've tested this change (Ubuntu xterm & uxterm, Mac
OS X Terminal & iTerm2).

Resolves issue #1464.

and puts object files into an obj/ directory. The Makefile
