* stable-2.5:
  Fix Makefile.am compatibility with automake 1.11.2

Signed-off-by: Michael Hanselmann <hansmi@google.com>
Reviewed-by: Iustin Pop <iustin@google.com>

Automake 1.11.2 made the following change:

* Long-standing bugs:
  - Automake now warns about more primary/directory invalid combinations,
    such as "doc_LIBRARIES" or "pkglib_PROGRAMS".

Unfortunately, this breaks our Makefile.am (issue 216) exactly because
we were relying on pkglib_SCRIPTS.

This patch works around this by adding a new myexeclibdir variable
(exec so that it is intalled at `install-exec` time, the same as the
pkglibdir), and switches to that.

The vgreduce command has changed behaviour from when we initially
wrote the code (2.02.02 versus 2.02.66, 4 years delta):

- if there are LVs which will be impacted, it requires --force
- otherwise refuses to proceed, but it still returns exit code 0

We handle this by looking to see if it returns "Wrote out consistent
volume group" (behaviour unchanged), or if it complains about
"--force"; in the case it didn't complete, we retry the operation.

We improve a bit the checking of "vgs", as it uses to fail silently
and we didn't detect it.

New tests for this function should test, I believe, all the expected
variations; at the least we now have data files with the expected
output.

This is a partial cherry-pick from
7530364d on master:

Currently, noded requires PUT, even though the semantics of the RPC
calls do not match a PUT. We change the code accept both PUT and POST,
with the intention to remove the PUT support in a later version.

Additionally, we add a message to the HttpBadRequest exception to make
clear the failure mode (not seeing any error message was what made me
send this patch…). This was the only description-less use of this
exception, by the way.

What was not cherry-picked is the rpc change (to switch to PUT). The
reason I want to backport this to devel-2.5 is that when upgrading to
2.6, having noded accept both makes for an easier upgrade path.

Just using ht.TListOf as a type check doesn't work correctly. The
function must be called with the expected item type. In this specific
case TListOf was always called with the filter as a value, and the
result of that call evaluated to truth. Since filters can be quite
complex there's no check yet, and therefore just “TList” is used.

Some Python scripts in /usr/lib/ganeti/ were getting the wrong permissions
(their 'x' bit was cleared).  This patch fixes that behavior.

This patch renames the variable 'dist_tools_PYTHON' to 'python_scripts'.
Some Python scripts were listed in the 'dist_tools_PYTHON' variable, but as
said scripts have no .py extension in their names, Automake treated the scripts
as data files, and hence no 'x' bit.  Now the Python scripts are processed
by the rules created for the 'dist_tools_SCRIPTS' variable, and such rules
don't depend on file name extensions.

(cherry picked from commit 0f796800)

This patch attempts to fix a number of issues with “gnt-cluster verify”
in presence of multiple node groups and DRBD8 instances split over nodes
in more than one group.

- Look up instances in a group only by their primary node (otherwise
  split instances would be considered when verifying any of their node's
  groups)
- When gathering additional nodes for LV checks, just compare instance's
  node's groups with the currently verified group instead of comparing
  against the primary node's group
- Exclude nodes in other groups when calculating N+1 errors and checking
  logical volumes

Not directly related, but a small error text is also clarified.

Cleanup just updates the config with the correct location of the
instance, or informs of its down status, but never starts it. As such
there's no point in checking for enough free memory. Actually this check
could prevent a perfectly safe cleanup operation if a node is busy.

Python's “optparse” module does option name prefix matching by default.
Since this can lead to confusing behaviour, e.g. by specifying “--force”

When an opcode is about to be processed its dependencies are
evaluated using “_JobDependencyManager.CheckAndRegister”. Due
to its nature that function requires a lock on the manager's
internal structures. All of this happens while the job queue
lock is held in shared mode (required for the job processor).

When a job has been processed any pending dependencies are re-added
to the job workerpool. Before this patch that would require
the manager's lock and then, for adding the jobs, the job queue
lock. Since this is in reverse order it will lead to deadlocks.

In this test the “file ID” of a temporary file is compared against the
file ID gathered via an open file descriptor to the same file. For
reasons unknown to me utime(2) is called in-between to update the
inode's a- and mtime. Depending on the file system's timestamp
resolution this can lead to a different file ID.

Found by chance during QA and reproduced by adding a delay before the
call to utime(2).
