This patch adds a configure-time parameter that will set the defaults
used by all programs, and command-line parameters in the daemons that
allow overriding it.

Syslog 'yes' enables syslog in addition to file-based logging, 'only'
enables syslog and disables file-based syslog.

The log entries will be of the form:
Jan 27 08:45:04 node2 ganeti-noded[14504]: INFO 172.24.227.5:50850 PUT
/jobqueue_update HTTP/1.0 200

/lv_list HTTP/1.0 200

and (for a multi-threaded program):
Jan 27 08:51:48 node1 ganeti-masterd[15491]: (MainThread) INFO

Ideally we want to/will have per-device DRBD controls of disk/metadata
flushes. In the meantime, we want at least a disable of the barrier
functionality for cases where one has battery-backed caches.

Background: DRBD has four mechanism of handling ordered disk-writes.
From the drbdsetup man-page, these are: barrier, flush, drain and none.
DRBD prior to 8.2 only has drain and none. This patch makes all 8.x
versions of DRBD disable all methods, and revert to none, in case one
fully trusts batteries (either UPS for the whole system or battery for
NVRAM).

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.

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.

This patch adds three optional parameters:

  - '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.

This big patch converts the documentation build system to sphinx
(http://sphinx.pocoo.org/

). Since that uses reStructuredText sources
too, there is no change (yet) in the documents themselves, just in the
build system.

As before, the docs are pre built by the maintainer, and the end-user
doesn't need sphinx or other rst tools to build the docs. Note that we
are not distributing PDFs, so building that will require the tools.

The docs will be stored under doc/html and the build system also need an
extra directory doc/build. These are considered (by automake)
maintainer-related objects and are removed at maintainer-clean time.

The patch also fixes some small issues: add a docpng variable, add
doc/api (also generated by maintainer) in maintainer-clean-local, etc.

This patch changes the way documentation is built in order to distribute
the generated output in the 'dist' archive, and thus no longer
requiring the presence of the docbook/rst toolchains during build time.
This will lower the requirements for installation and also makes the
build time insignificant.

First, we remove the docbook2pdf rules and variables, since we no longer
build this kind of docs. Furthermore, the rst source files are not
(today) processed via replace_vars_sed, so the whole .in rules for doc/
go away.

Next, we change the ".sgml|.rst -> replace_vars_sed -> .in -> processor
-> final file" processing to ".sgml|.rst -> generator -> .in ->
replace_vars_sed -> final file"; this means we first process the file
using the formatter, with the @VARIABLE@ entries in it, and save the
output as .in; this output we distribute, and on the user side, the
replace_vars_sed will use the new configure flags to transform the
(almost final .in form) to the final form, without needing the
toolchain.

In configure.ac we also change from ERROR to WARN for the documentation
generators, and extra tests in Makefile.am check that the programs have
been found.

This was tested with distcheck and works as expected.
