1.11.1 is the version in squeeze and lucid, and we know it works. We
also know that 1.10.1 in hardy and lenny doesn't, nor do 1.10 in etch
and 1.9.6 in dapper. We haven't tested any other version.

With older versions python.m4 is buggy, and results in the package being
built not working on python 2.6 (which uses dist-packages rather than
site-packages as a module directory).

The autogen.sh interpreter is changed to bash, as we need to use the [[
builtin to compare versions with "<". [ doesn't have that functionality,
and we can't of course rely on dpkg, which won't be installed on all
distributions.

This time, we re-establish the old pri/sec nodes corretly. Unfortunately this
will require now a 3-node cluster at least for drbd instances, hence it's
somewhat suboptimal, but… The other option would be to move it simply from p:s
to s:p and then back to p:s, without involving a third node (for DRBD case),
but I think that moving it to a completely separate node is slightly better for
testing.

The instance move tests were moving the instance from node pair (A,_) to
(B, A), and left it there. This patch makes sure that the first step
moves the instance to (B,A) but the second one back to (A,B), so that
the instance is left on the same primary node.

The original secondary node is lost though, if I read the code
correctly.

Using hugepages, KVM instances can get a good performance boost. To
activate that, we need to pass the -mem-path argument to KVM along with
the mount point of the hugetlbfs file system on the node.

For the sake of memory availability computation, we use the -mem-prealloc
argument when enabling hugepages, so KVM will reserve all hugepages it
needs when it starts. This avoids allocating an instance on a node that
will not have enough pages in case other instance needs more than what
is available after it boots.

The OS list and variants as returned from LUDiagnoseOS is not sorted,
and gnt-instance reinstall doesn't sort it either. This means that it
the menu that users are present with is inconsistent across clusters,
and that is confusing.

To make this consistent across all users of the LU, we sort the names in
the LU itself.

This patch changes the behaviour of OpDiagnoseOS with regards to the
'valid' field to be similar to the one for the hidden/blacklisted
fields: unless this field is requested, invalid OSes are filtered out.

The rationale is that, except for the gnt-os info/diagnose, all other
users of this opcode are requesting the valid field just to filter out
invalid OSes, and not for any other use. Thus, changing this behaviour
makes these callers simpler.

This changes the behaviour of LUDiagnoseOS significantly.

The addition of hidden/blacklisted OSes would mean that each user-facing
client would have to filter intentionally such OSes from display, which
is not a good choice. Rather, the patch makes LUDiagnoseOS not return
any hidden or blacklisted OSes unless the hidden or respectively the
blacklisted status is requested.

While unconventional, this makes `gnt-instance reinstall --select-os`
work as intended without any changes; similar for gnt-os list. gnt-os
diagnose/gnt-os info are changed to query for, and display the new
fields.

The new variables are:

- a list of hidden OSes, that should not be displayed to the users in
  interactive selection (e.g. reinstall); however, if they are selected, they
  can be used
- a list of OSes that should be hidden and blocked from install-time selection

The filtering will apply at pure OS name level, not OS+variant level.

Currently, the computation of the 'pure' name or the variant is
hardcoded and spread around the functions that need it. This is not
nice, and in the future we'd spread it even more with more usage of
variants/pure os names.

This patch abstracts these functions into the OS class, and then
replaces the hardcoded uses with the new functions.
