e2fsprogs: remove findfs option

The e2fsprogs package's findfs option provides no capabilities. When the
option is selected, a symbolic link is generated from findfs to e2label;
however, e2label will not handle findfs since the respective code is
explicitly disabled when `--disable-libblkid` is passed in. At this
time, the e2fsprogs package only supports findfs capabilities when
building its "private blkid library".

Note that the `--disable-libblkid` configuration argument must remain
to prevent conflicts with util-linux's libblkid and an e2fsprogs-
generated variant (see e1ffc2f791b336339909c90559b7db40b455f172).

Since e2fsprogs cannot provide findfs capabilities, the option is being
removed in this change. A following change will be introduced to include
util-linux's findfs utility.

linux: add conditional patch for timeconst.pl

Kernels older than 3.9 (not counting stable releases) used the
timeconst.pl perl script for their build process.
The problem with this script is that it used deprecated perl features,
namely defined(@array) which was removed for the perl 5.22 release,
causing build failure of older kernels on newer distributions.

To fix this instead of going the hard way (moving to the new
timeconst.bc script) use the easy way by patching timeconst.pl with an
upstream patch used for stable releases.

First try a dry-run on the patch to see if it applies, if it does then
call a proper APPLY_PATCHES to it.

Tested against an arbitrary 2.6.30 kernel (applies and builds), against
4.4.1 for a missing timeconst.pl (does not apply since it's missing) and
3.8.13 (does not apply since it's fixed already).

docs/manual: update graph-depends documentation about --stop-on

This commit updates the graph-depends documentation to take into

--exclude options.

graph-depends: add support for excluding host packages

Just like the --stop-on and --exclude options allow to stop on or
exclude virtual packages from the list by passing the "virtual" magic
value, this commit extends the graph-depends logic to support a "host"
magic value for --stop-on and --exclude. This will allow to draw the
graph by stopping on host packages, or by excluding host packages.

graph-depends: fix handling of "virtual" in exclude_list

The condition to determine if a virtual package should be excluded
from the list due to "virtual" being passed in --exclude is under a
loop iterating over each entry of the exclude_list, but it doesn't use
the iterator of this list.

Indeed, the condition contains:

"virtual" in exclude_list

which checks automatically if "virtual" was passed in the list. Due to
this, there is no need for this check to be within the "for p in
exclude_list" iteration. This commit fixes that by moving the check
outside of the loop.

support/graph-depends: detect circular dependencies

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
dependency check:

core: catch failures in graph-depends

Currently, we generate the dependency graph in a single command, piping
the stdout of support/scripts/.graph-depends to the stdin of dot.

Unfortunately, this means we can't catch a failure of graph-depends, as
the shell can only treturn the exit code of the last command in a pipe.

Still, we do want to keep the output of graph-depends, and we in fact do
keep it by mean of a tee.

graph-depends has just gained the ability to generate its output to a
file, so we break the pipe in two differnet commands, so we can bail out
on graph-depends errors.

Do that for the two call sites.

support/graph-depends: add option to specify output file

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.

package/avahi: break circular dependencies

We currently have two circular dependency chains:

    avahi -> libglade -> libgtk2 -> cups -> avahi
    avahi -> libgtk3 -> cups -> avahi

The cups -> avahi dependency makes sense, as cups would be able to use
Bonjour and mDNS to find printers, so we want to keep that dependency.

The libgtk2 -> cups and libgtk3 -> cups dependencies also make sense, to
be able to offer cups in the print dialogs.

However, the avahi -> libglade and avahi -> libgtk3 dependencies do not
really make sense. As Thomas puts it:

    The avahi GUI programs seem really useless to me. On Debian/Ubuntu
    distributions, they are not even packaged within the main avahi
    packages, but as separate packages, probably indicating that they
    are not very commonly used.

So, we drop the avahi -> libglade and avahi -> libgtk3 dependencies, to
break the circular dependency chain.
