First, we don't need to check man pages at sed time, because this means
everyone building the package will do - we only need to check at docbook
time, which is mostly at developer time.

Second, don't force LC_ALL to C, as this breaks newer man-db. I've
verified and removing LC_ALL works fine across etch, hardy, lenny aid
squeeze/sid.

X509 uses ASN1 GENERALIZEDTIME or UTCTIME to store certificate validity.
pyOpenSSL 0.7 and above allow us to retrieve both “notBefore” and
“notAfter” as strings. Parsing them turned out to be a challenge since
they can be in a variety of formats (YYYYMMDDhhmmssZ, YYYYMMDDhhmmss+hhmm
or YYYMMDDhhmmss-hhmm).

This will be used to verify the validity of cluster certificates in
LUVerifyCluster.

Rationale: the file-based storage backend can add/remove files under a
certain directory. However, the master node is also controlling the
setting of the file-based root directory, so basically it means we can't
prevent arbitrary modifications by the master of the node's filesystem.

In order to mitigate this for setups where the file-based storage is not
used, we introduce a new setting at ./configure time, that controls the
enable/disable of file-based storage. Since this is not modifiable by
the master (over RPC), it is now possible in this case to prevent
unintended modifications of the node's filesystem from the master.

The new setting is used in bdev.py to not expose the file-based storage
at all, and in cmdlib.py to prevent attempts at creation of such
instances.

On fork, the tempfile module's pseudo random generator is
not reset. If several processes (e.g. two children or parent
and child) try to create a temporary file, they'll conflict.
This function can be used to reset the name generator which
contains the pseudo random generator.

A unittest is included. It is in a separate script because
it changes a variable in the tempfile module to speed up the
test.

A long PREFIX variable (to configure) will result in very long
LOCALSTATEDIR, which when concatenated with lib/ganeti/ (and even more
items under it) will go over the 80 char line length we enforce in the
man checker.

To workaround this, we change two things:

- use a specific REPLACE_VARS_MAN which adds breaking points after each
  slash in paths
- replace some <filename> entries with <literallayout> so that docbook
  generates a non-fill block around them (only a few cases need this
  after the breaking points are added

Note that with normal prefixes (e.g. / or /usr/local) this won't happen.

The patch also fixes a wording in the watcher man page.

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).

and we also distribute doc/rapi-resources.gen since otherwise “make
