d4398aea89 zdev: Adjust zdev modprobe path to be compatible with split-usr systems.
mk-pxelinux-ramfs, mod_fsstatd|procd.service, zfcpdump all use
/sbin/modprobe path. Adjust zdev to use that path as well. This works
universally on both usr-merge systems (e.g. Debian/Ubuntu with
usrmerge package installed), and split-usr systems alike
(Debian/Ubuntu current stable releases default).

Closes: #31

fe68ec513d zdev: Add support for handling auto-configuration data
Auto-configuration is the name of a new configuration target that is
supported by chzdev and lszdev besides the existing active and
persistent configuration targets. Directives created in this new
configuration are stored as udev rules in the /run/udev/rules.d
directory.

Auto-configuration directives are only in effect if there are no
directives for the same device in the user-provided persistent
configuration. This allows users to override auto-configuration
directives if necessary.

Due to the volatile nature of the /run directory, auto-configuration
directives are cleared on reboot. Therefore mechanisms that generate
auto-configuration directives must recreate them on every boot.

The lszdev tool displays auto-configuration data both in list view
as well as in detail view. Users can specify the new option --auto-conf
to only show data from this configuration target.

Mechanisms that generate automated configuration directives can use
chzdev together with the --auto-conf option to create the corresponding
udev rules.

Note: This change does not include a mechanism that generates
      auto-configuration directives.

a060dc22db zdev: Use correct path to vmcp binary
The zdev tools use a hard-coded path to locate the vmcp binary. Since
this path may differ between distributions, the vmcp binary may not be
successfully located in all cases. Fix this by using the BINDIR macro
to determine the correct path. This macro is also used during
installation of the vmcp binary itself.
