Sometimes colour can help show what is different between two strings.
This is roughly the same as
`git diff --no-index --color-words=. <a> <b>`.

We need this for `samba-tool visualize -o -` which means output to
stdout, and which has always had a tty test for colour. Rather than
continue to duplicate the full logic there, we can reuse this.

More often than not we are using colour in stderr, but are deciding
based on stdout's tty-ness. This patch changes to use both, and will
affect the following situation:
samba-tool 2>/tmp/errors # used to be colour, now not.
of course, if you want colour, you can always
samba-tool --color=yes 2>/tmp/errors

The accepted hints are presumably arguments to --color.
We follow the behaviour of `ls` in what we accept.
`git` is stricter, accepting only {always,never,auto}.
`grep` is looser accepting mixed case variants.
historically we have used {yes,no,auto}.

When samba.colour is first imported, the function
colour.c_BLUE("samba")
will give you the string "\033[1;34msamba\033[0m", which will show up
as blue on an ANSI terminal. If you then go:
colour.switch_colour_off()
colour.c_BLUE("samba")
the c_BLUE call will return the uncoloured string "samba".
This is so things like samba-tool can do this sort of thing:
if not os.isatty(self.outf):
switch_colour_off()

This is going to be used by `samba-tool visualize` and samba_kcc.
