We were bridging the gap between the server and UI here by calling a
bb.siggen.find_siginfo, a function defined and set on that module from
the metadata. This worked from the UI side before but since the recent
server changes is no longer accessible. Create a new command so this can
execute on the server side and return the result by way of a new event.
(We're still running compare_sigfiles() on the signature generator but
that isn't quite the same thing and does still work.)
Fixes [YOCTO #11844].

In the move over to argparse we've made the two signature file arguments
optional and thus if -t is not in use we need to explicitly check if at
least one signature file has been specified - and if not, show an error
and the command-line help.

If the output is a TTY, add colour to the output in order to make it
easier to read. At the moment this is fairly basic, just add colour to
the "titles" of each change and to the diff output.
I tried to introduce this without changing the code too much - rather
than moving everything over to the new python formatting style, I've
introduced a color_format() function which takes care of the colour
formatting, either accepting additional format arguments or
alternatively leaving the caller to use the old-style formatting (%) to
insert values.

With the -t option which recurses to find the ultimate cause of a
signature change, it was hardcoded to take the last two executions of
the specified task. On the other hand, if you have two specific task
hashes (say from bitbake output, or some other tool) then you'll want to
pick those, so provide an option to specify those as well. (Note, the
new -s option needs to be specified alongside -t rather than instead of
it.)

When dumping changes to signatures e.g. output of bitbake -s printdiff,
if for example a function has changed, it's much more readable to see a
unified diff of the changes rather than just printing the old function
followed by the new function, so use difflib to do that.
Note: I elected to keep to one item in the returned list per change,
rather than one line per line of output, so that the caller can still
look at changes individually if needed. Thus I've added some handling to
bitbake-diffsigs to split the change into lines so that each line is
displayed indented.

This logic doesn't work in practice, certainly not with current versions
where sigdata files are preserved in the stamps directory and therefore
there will often be multiple sigdata files - you can now easily get
files for the same signature from sstate and the stamps directory with the
result that bitbake-diffsigs reports nothing has changed. Instead, let's
change the find_siginfo function in OE-Core to simply not return
duplicates so we don't have to filter them out here.

If just one of the two signatures we want to compare aren't available,

We weren't picking the right files to compare here - according to the
order in which the list is sorted (by mtime), we need to be taking the
last two items and not the first two.

We use this code to set up a logger with colour in a number of different

utility scripts use it.

having the same hash values
For now, `bitbake-diffsigs -t <recipe> <task>' doesn't work. It always outputs
nothing.
The problem is that bitbake-diffsigs are comparing sigdata and siginfo files
that have the same hash value. This is not what we want. These two files are
actually duplicates considering the purpose of bitbake-diffsigs. So we need
to remove one of them so that bitbake-diffsigs could actually compare the
correct signature files.

If bitbake-diffsigs is run without arguments it will error:
Traceback (most recent call last):
File "./bin/bitbake-diffsigs", line 121, in <module>
if output:
NameError: name 'output' is not defined
Fix this by moving the check for output into the inner else-clause.

Add the ability to compare the two most recent runs of a specified task,
and follow dependent hash changes recursively. This enables you to trace
back and find exactly why a task was re-run after the fact.
Note that this relies on the metadata providing a function, hooked in
as bb.siggen.find_siginfo, which allows searching in the appropriate
places to find signature data files.
