Now that we can get the whole dependency tree from make, use it to
speed up things considerably.
So far, we had three functions to get the dependencies information:
get_depends(), get_rdepends(), and, somehow unrelated, get_version().
Because of the way %-show-{,r}depends works, getting the dependency tree
was expensive, the three functions all took a set of packages for which
to get the dependencies, in an attempt to limit the time it took to get
that tree, but we still had to call these functions iteratively, until
they returned no new dependency. This was pretty costly.
Now, getting the tree is much, much less costly, and we can get the
whole tree as cheaply as we previously got only the first-level
dependencies.
Furthermore, we can now also get the version information at the same
time, and that also brings in whether the package is virtual or not,
target or host.
So, we drop all three helper functions, and replace them with a single
one that returns all that information in one go: full dependency trees
(direct and reverse), per-package type, and per-package version.
Note: since commit 2d29fd96a (pkg-virtual: remove VERSION/SOURCE),
virtual packages are no longer reported as having a 'virtual' version,
so have since been displayed as regular packages in the graphs. Although
noone complained, this patch incidentally restores the initial
behaviour, and virtual packages are now correctly displayed as such
again.

We we simplify the dependency graph, we try to remove so-called
mandatory dependencies from each package, and for each mandatory that
was thus removed, reattach it to the root-package of the graph.
This was made so that mandatory dependencies (which are dependencies of
all packages, or at least of a lot of packages) do not clutter the
dependency graph, but that they are still shown in the graph, as
dependencies of the root package.
However, these mandatory dependencies are only _direct_ dependencies.
As such, it does not make sense to reattach a mandatory dependency when
doing a reverse graph. Worse, it can actually be incorrect.
For example, 'skeleton' is a mandatory dependency, and as such is
removed from all packages. But when doing a reverse graph, skeleton is
now in the dependency chain of, e.g. skeleton-init-none; it should then
not be removed.
In short: the notion of mandatory dependencies does not make sense in
the case of a reverse graph.
Consequently, skip over the mandatory dependency removal when doing a
reverse graph.

Some times, multiple dependency graphs for a set of packages (mostly
the application-level packages for the project) are included in reports
(e.g. delivery notes). Repeating the mandatory dependencies on all
those graphs is useless and clutters the important dependencies.
When we had only two such mandatory dependencies (toolchain, skeleton),
it was manageable to list them as manual exclusions:
-x toolchain -x skeleton
But we now have quite a few such dependencies, and it becomes a bit more
cumbersome to manage, not counting the ones we may add in the future.
Add an option to exclude all those mandatory dependencies, to generate
neat graphs.

The current graph-depends implementation filters out a number of
"mandatory" dependencies that all packages have: dependency on
"toolchain" and dependency on "skeleton".
Despite this filtering, in full graph dependencies, "toolchain" and
"skeleton" are still shown, because they are target packages, and
therefore appear in the result of "make show-targets". Thanks to this,
they will be visible as dependencies of the "ALL" node, which is the
root of the dependency tree.
However, as we are going to introduce host-skeleton as a "mandatory
dependency" to be filtered out, this is no longer going to work.
This commit adjusts the remove_extra_deps() function to ensure that
when a mandatory dependency is removed, this dependency exists between
the root of the dependency tree and the mandatory dependency.
This issue was noticed by Yann E. Morin, and this commit provides a
different implementation than what Yann proposed in
https://patchwork.ozlabs.org/patch/910453/.

The remove_extra_deps() function removes dependencies that we are not
interested in seeing in the dependency graph. It does this for all
packages, except the 'all' package, which on full dependency graphs is
the root of the tree.
However, this doesn't take into account package-specific dependency
graphs (i.e make <pkg>-graph-depends) where the root is not 'all', but
'<pkg>'. Due to this, dependencies on "mandatory deps" were not
visible at all, i.e the toolchain package (and its dependencies) and
the skeleton package (and its dependencies) were not displayed in
package-specific dependency graphs.
To fix this, we use the existing rootpkg variable instead of
hardcoding 'all'.

Currently, we avoid drawing the dependencies that we call 'target
exceptions', becasue they initially were returned by 'show-targets',
when they in fact were not really packages and thus should not be on
the graph.
However, those two exceptions have no longer been reported in the output
of show-targets since we merged very old initial top-level parallel
build way back in 2014, with commit a24877586a (Makefile: add support
for top-level parallel make), where they had been converted into purely
internal rules.
4 years have passed, we can now drop those exceptions from the
graph-depends script.
This concludes the cleanup initiated three years ago with commit

The graph-depends script had no main() function, and the main code was
actually spread between the function definitions, which was a real
mess.
This commit moves the global code into a main() function, which allows
to more easily follow the flow of the script. The argument parsing
code is moved into a parse_args() function.
Most of the global variables are removed, and are instead passed as
argument when appropriate. This has the side-effect that the
print_pkg_deps() function takes a lot of argument, but this is
considered better than tons of global variables.
The global variables that are removed are: max_depth, transitive,
mode, root_colour, target_colour, host_colour, outfile, dict_deps,
dict_version, stop_list, exclude_list, arrow_dir.
The root_colour/target_colour/host_colour variables are entirely
removed, and instead a single colours array is passed, and it's the
function using the colors that actually uses the different entries in
the array.
The way the print_attrs() function determines if we're display the
root node is not is changed. Instead of relying on the package name
and the mode (which requires passing the root package name, and the
mode), it relies on the depth: when the depth is 0, we're at the root
node.

Currently, if there is a circular dependency in the packages, the
graph-depends script just errors out with a Python RuntimeError which is
not caught, resulting in a very-long backtrace which does not provide
any hint as what the real issue is (even if "RuntimeError: maximum
recursion depth exceeded" is a pretty good hint at it).
We fix that by recursing the dependency chain of each package, until we
either end up with a package with no dependency, or with a package
already seen along the current dependency chain.
We need to introduce a new function, check_circular_deps(), because we
can't re-use the existing ones:
- remove_mandatory_deps() does not iterate,
- remove_transitive_deps() does iterate, but we do not call it for the
top-level package if it is not 'all'
- it does not make sense to use those functions anyway, as they were
not designed to _check_ but to _act_ on the dependency chain.
Since we've had time-related issues in the past, we do not want to
introduce yet another time-hog, so here are timings with the circular

Currently, graph-depends outputs the dotfile program to stdout, and uses
stderr to trace the dependencies it is currently looking for.
Redirection was done because the output was directly piped into the dot
program to generate the final PDF/SVG/... dependency graph, but that
meant that an error in the graph-depends script was never caught
(because shell pipes only return the final command exit status, and an
empty dot program is perfectly valid so dot would not complain).
Add an option to tell graph-depends where to store the generated dot
program, and keep stdout as the default if not specified.

6 minutes and 39 seconds. Here is a timing of the different
graph-depends steps and the overall execution time:
Getting dependencies: 42.5735 seconds

Add a new option to graph-depends, that users can set to stop the graph
on a specific (set of) package(s).
This accepts any actual package name, or the 'virtual' keyword to stop
on virtual packages.

Most of targets listed in TARGET_EXCEPTIONS these days are long
gone, so why still keep them?
Most of those targets were removed in this commit:

The graph-depends script calls make. If the outer make was called
recursively, or if it was called with '-C <somedir>', then the
environment will contain "MAKEFLAGS=w --". Therefore, the recursive
make prints 'Entering' and 'Leaving' messages, which clobbers the
output for dot.
To avoid this, add "--no-print-directory" to the recursive make
arguments. Since we require GNU make 3.81, we can be sure that this
option is available.

This patch is the result of 2to3.
In addition, universal_newlines=True is added to the Popen calls. In
python3, this makes sure that the output is decoded so that we get a
string instead of a buffer object.

The transitive dependencies make the graphs barely readable for large
configs, with a large number of packages.
So, just switch to not drawing the transitive dependencies by default.
By popular demand... ;-)

This is ugly, since Python does not have enum constructs, so by moving
the 'type' of the constant ('MODE' here) to the beginning, we get an
artificial 'namespace' for the constants.

initialise the 'transitive' option, and document it at the same time.

Merge the redundant-dependencies elimination into the newly introduced
transitive-dependencies elimination.
This makes the code cleaner and much shorter, because:
- the ('all',pkg) redundant dependency is in fact a transitive
dependency, and we now have code to deal with that
- the (pkg,'toolchain') dependency is easy enough to deal with that
having a separate function for that is overkill

Currently, all the dependencies of a package are drawn on the dependency
graph, including transitive dependencies (e.g. A->B->C and A->C).
For very big graphs, with lots of packages with lots of dependencies, the
dependency graph can be very dense, and transitive dependencies are
cluttering the graph.
In some cases, only getting the "build-order" dependencies is enough (e.g.
to see what impact a package rebuild would have).
Add a new environment variable to disable drawing transitive dependencies.
Basically, it would turn this graph:
pkg1 ---> pkg2 ---> pkg3 -------------------.
|\__________/ \ \
|\____________________ \ \
| \ \ \
`-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8
\__________/
into that graph:
pkg1 ---> pkg2 ---> pkg3 -----------.
| \
`-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8
