Mahesh Bandewar 5d5586b058 iproute: make clang happy
These are primarily fixes for "string is not string literal" warnings
/ errors (with -Werror -Wformat-nonliteral). This should be a no-op
change. I had to replace couple of print helper functions with the
code they call as it was becoming harder to eliminate these warnings,
however these helpers were used only at couple of places, so no
major change as such.

Allow for -color={never,auto,always} to have colored output disabled,

Phil Sutter 4d82962ccc Merge common code for conditionally colored output
Instead of calling enable_color() conditionally with identical check in
three places, introduce check_enable_color() which does it in one place.

Vincent Bernat 1ca4341d2c color: disable color when json output is requested
Instead of declaring -color and -json exclusive, ignore -color when
-json is provided. The rationale is to allow to put -color in an alias
for ip while still being able to use -json. -color is merely a
presentation suggestion and we can assume there is nothing to color in
the JSON output.

Petr Vorel 24b058a2a4 color: Fix another ip segfault when using --color switch
Commit 959f1428 ("color: add new COLOR_NONE and disable_color function")
introducing color enum COLOR_NONE, which is not only duplicite of
COLOR_CLEAR, but also caused segfault, when running ip with --color
switch, as 'attr + 8' in color_fprintf() access array item out of
bounds. Thus removing it and restoring "magic" offset + 7.

Reproduce with:
$ ip -c a

Phil Sutter a1121aa1f5 color: introduce color helpers and COLOR_CLEAR
This adds two helper functions which map a given data field to a color,
so color_fprintf() statements don't have to be duplicated with only a
different color value depending on that data field's value. In order for
this to work in a generic way, COLOR_CLEAR has been added to serve as a
fallback default of uncolored output.

Mathias Nyman d7bd2db52c ip: Add color output option
It is hard to quickly find what you are looking for in the output of the
ip command. Color helps.

This patch adds a '-c' flag to highlight these with individual colors:
  - interface name
  - ip address
  - mac address
  - up/down state
