This patch adds a new success condition for identifying DRBD8 devices:
if the local device is correct, but the network peer is not, we shutdown
the network and attach to the correct one (this also handles going to
standalone mode).

This new check (and its actions) is based on the fact that we don't pass
incorrect data from the master to the node (otherwise we could start
syncing with an incorrect peer.

This patch adds a check in _AssembleNet so that if we are passed None
value in the unique_id, we instead switch to standalone mode.

This patch adds a simple man page for the master startup script and
modifies the footer.sgml fragment to include it.

The /var/run directory can be a tmpfs mount, so even if we make it at
install time (or include it in the package) it can go away. Therefore,
test for its existence and create it in the startup script.

The docdir variable is defined by autoconf, so we don't need to define
it ourselves. This way, the target documentation directory can
be changed via ./configure instead of patching Makefile.am.

In truth, we should install the pdf and html files using the pdf and
html targets, since configure defines pdfdir=htmldir=docdir; but
installing them in docdir is good enough.

Right now an assembly error produces an exception but not a log message. This
is bad because the exception suggests looking at the log, but the log itself
has a lot of errors which are not really a problem and only some which really
is. In order to make it clear where in the log the problem occurred we log a
message too, before raising the exception.
