Since this is easily configurable at run-time, we remove the
configure-time parameter. If anyone is building custom packages, then
the default can be tweaked by a one-line patch to constants.py.

Note that this also fixes the type of parameter, the default from
_autoconf.py is a string parameter. Shouldn't matter except if a cluster
run code between commit 78411c60 and this one.

Until now, Ganeti started and stopped its own daemons using custom functions.
To start, the daemon was just executed and then sent the appropriate signals to
stop it again. Init scripts would have to pay attention to the PID file and
other things.

With this patch, a new script is added (“daemon-util”, installed in
$prefix/lib/ganeti/), centralizing the starting and stopping of daemons. The
provided example init script is adjusted to use this new script. Ganeti's code
no longer calls its own init script.

Currently we use a static value for the socat path, or we trust the
user-provided one. With this patch we still trust any user provided
value, but if none is passed we check for socat on the machine we're
being configured on. This allows us also to check if we can or cannot
use the escape= feature in socat.

If the user has forced the path in, he can also pass --with-socat-escape
in order to force the escape functionality to be used, even if a check
is not done.

Our admin guide was very very trivial. This patch updates it to contain
advice on when to use which commands, removes the instance
administration part from the installation guide (moved to the admin
guide), and adds a walkthrough document that should be useable as a
starting point for new admins.

The patch also adds emacs variables to the documents, and rewraps some
which were not already at 72 chars.

The doc updates also show backwards-compatible commands for Ganeti 2.0,
as we don't have a good up-to-date 2.0 document and people might refer
to this set of documentation even when running that.

This was implemented in 350ecfec and reverted in 700bb843
after it broke “make distcheck”. With other changes in this
patch series this will work now.

Contributing to the original problem was that the news.rst file
was not distributed. When we distribute the build documentation,

This patch adds three optional parameters:
  - 'use_bootloader', whether use or not the bootloader
  - 'bootloader_path', absolute path to the bootloader
  - 'bootloader_args', extra arguments to the bootloader

Syntax:
  gnt-cluster modify --hypervisor-parameters \
    xen-pvm:bootloader_path=/usr/bin/pygrub,use_bootloader=False
  gnt-instance modify -H use_bootloader=True instance1.example.com

If use_bootloader is True, each domU can boot with its own kernel
instead of using the dom0 kernel.
