3759d27aca parse_color: fix return value for numeric color values 0-8
When commit 695d95d refactored the color parsing, it missed
a "return 0" when parsing literal numbers 0-8 (which
represent basic ANSI colors), leading us to report these
colors as an error.

ff40d185d2 parse_color: recognize "no$foo" to clear the $foo attribute
You can turn on ANSI text attributes like "reverse" by
putting "reverse" in your color spec. However, you cannot
ask to turn reverse off.

For common cases, this does not matter. You would turn on
"reverse" at the start of a colored section, and then clear
all attributes with a "reset". However, you may wish to turn
on some attributes, then selectively disable others. For
example:

  git log --format="%C(bold ul yellow)%h%C(noul) %s"

underlines just the hash, but without the need to re-specify
the rest of the attributes. This can also help third-party
programs, like contrib/diff-highlight, that want to turn
some attribute on/off without disrupting existing coloring.

Note that some attribute specifications are probably
nonsensical (e.g., "bold nobold"). We do not bother to flag
such constructs, and instead let the terminal sort it out.

17a4be2606 parse_color: support 24-bit RGB values
Some terminals (like XTerm) allow full 24-bit RGB color
specifications using an extension to the regular ANSI color
scheme. Let's allow users to specify hex RGB colors,
enabling the all-important feature of hot pink ref
decorations:

  git log --format="%h%C(#ff69b4)%d%C(reset) %s"

cb357221a4 t4026: test "normal" color
If the user specifiers "normal" for a foreground color, this
should be a noop (while this may sound useless, it is the
only way to specify an unchanged foreground color followed
by a specific background color).

We also check that color "-1" does the same thing. This is
not documented, but has worked forever, so let's make sure
we keep supporting it.

5935c581df t4026 (color): remove unneeded and unchained command
Ever since 8b12413 (color: allow multiple attributes 2010-02-27),
diff.color.new has been unused in t4026, so also remove the final unsetting
of that value to make the third to last test pass with appropriate
'&&' chaining.

8b124135a9 color: allow multiple attributes
In configuration files (and "git config --color" command line), we
supported one and only one attribute after foreground and background
color.  Accept combinations of attributes, e.g.

    [diff.color]
            old = red reverse bold

8b8e862490 ignore unknown color configuration
When parsing the config file, if there is a value that is
syntactically correct but unused, we generally ignore it.
This lets non-core porcelains store arbitrary information in
the config file, and it means that configuration files can
be shared between new and old versions of git (the old
versions might simply ignore certain configuration).

The one exception to this is color configuration; if we
encounter a color.{diff,branch,status}.$slot variable, we
die if it is not one of the recognized slots (presumably as
a safety valve for user misconfiguration). This behavior
has existed since 801235c (diff --color: use
$GIT_DIR/config, 2006-06-24), but hasn't yet caused a
problem. No porcelain has wanted to store extra colors, and
we once a color area (like color.diff) has been introduced,
we've never changed the set of color slots.

However, that changed recently with the addition of
color.diff.func. Now a user with color.diff.func in their
config can no longer freely switch between v1.6.6 and older
versions; the old versions will complain about the existence
of the variable.

This patch loosens the check to match the rest of
git-config; unknown color slots are simply ignored. This
doesn't fix this particular problem, as the older version
(without this patch) is the problem, but it at least
prevents it from happening again in the future.
