leveraging users.users.<user>.createHome instead of a preStart script.
preStart script is still required to ensure proper creation of logging
directory.
Release announcement, 2016-01-30:
https://www.sigrok.org/blog/major-sigrok-releases-libsigrok-libsigrokdecode-sigrok-cli-pulseview
I first tried updating the projects in separate commits. But later I
found cyclic dependencies, that would break git bisect, so I ended up
squashing the commits:
* libsigrok: 0.3.0 -> 0.4.0
Enable building libsigrokcxx.so, the C++ bindings for libsigrok, by
adding doxygen, glibmm and python as build deps. This is needed for
Pulseview >= 0.3.0. Also update the firmware (sigrok-firmware-fx2lafw)
while at it.
* libsigrokdecode: 0.3.0 -> 0.4.0
* sigrok-cli: 0.5.0 -> 0.6.0
* pulseview: 0.2.0 -> 0.3.0
New dependency: glibmm (due to libsigrokcxx.pc from libsigrok).
Note that collectd is incompatible with the new libsigrok release, so
I let it use the old one (0.3.0).
This reverts commit 6ff886e539 because it
doesn't work when chroot builds are enabled (nix.useChroot = true):
$ nix-build -A arduino
these derivations will be built:

BUILD FAILED
Reasoning: without a revert, the build farm cannot produce binaries and
users that build from source, without chroot, cannot trust that they get
a working result (non-deterministic build, depending on how pure the
arduino builder is).
