Fix a few job archival issues
This patch fixes two issues with job archival. First, the
LoadJobFromDisk can return 'None' for no-such-job, and we shouldn't add
None to the job list; we can't anyway, as this raises an exception:
node1# gnt-job archive foo
Unhandled protocol error while talking to the master daemon:
Caught exception: cannot create weak reference to 'NoneType' object
After fixing this, job archival of missing jobs will just continue
silently, so we modify gnt-job archive to log jobs which were not
archived and to return exit code 1 for any missing jobs.

burning: fix handling of empty job sets

Change handling of non-Ganeti errors in jqueue
Currently, if a job execution raises a Ganeti-specific error (i.e.
subclass of GenericError), then we encode it as (error class, [error
args]). This matches the RAPI documentation.
However, if we get a non-Ganeti error, then we encode it as simply
str(err), a single string. This means that the opresult field is not
according to the RAPI docs, and thus it's hard to reliably parse the
job results.
This patch changes the encoding of a failed job (via failure) to always
be an OpExecError, so that we always encode it properly. For the command
line interface, the behaviour is the same, as any non-Ganeti errors get
re-encoded as OpExecError anyway. For the RAPI clients, it only means
that we always present the same type for results. The actual error value
is the same, since the err.args is either way str(original_error);

Change the meaning of call_node_start_master
Currently, backend.StartMaster (the function behind this RPC call) will
activate the master IP and then, if the start_daemons parameter is true,
it will also activate the master role.
While this works, it has two issues:
- first, it will activate the master IP unconditionally, even if this
node will not start the master daemon due to missing votes
- second, the activation of the IP is done twice if start_daemons is
true, because the master daemon does its own activation too
This behaviour seems to be unmodified since Summer 2008, so probably any
rationale on why this is done in two places is forgotten.
The patch changes so that this function does *either* IP activation or
master role activation but not both. So the IP will be activated only
once (from the master daemon or from LURenameCluster), and it will only
be done if the masterd got enough votes for startup.
I can see only one downside to this change: if masterd won't actually
start (due to missing votes), RAPI will still start, and without the
master IP activated. But this is no worse than before, when both RAPI
was running and the IP was activated.
Note that the behaviour of StopMaster remains the same, as noone else
does the IP removal.

masterd: move the IP activation from Exec to Check
Currently, the master IP activation is done in the Exec function. Since
the original masterd process returns after forking, and Exec is run in
the (grand)child process, this means that after 'ganeti-masterd' has
returned there are still initialization tasks running.
Normally this is not a problem, but in cases where one does quick master
failovers, this creates a race condition which hits the QA scripts
especially hard.
To solve this, and make the startup process cleaner (the system is in
steady state after the command has returned, even though masterd startup
could still fail), we move the IP activation to Check(). This also
allows error messages about the IP activation to be seen on the console.

watcher: smarter handling of instance records
This patch implements a few changes to the instance handling. First, old
instances which no longer exist on the cluster are removed from the
state file, to keep things clean.
Second, the instance restart counters are reset every 8 hours, since
some error cases might be transient (e.g. networking issues, or machine
temporarily down), and if the problem takes more than 5 restarts but is
not permanent, watcher will not restart the instance. The value of 8
hours is, I think, both conservative (as not to hammer the cluster too
often with restarts) and fast enough to clear semi-transient problems.
And last, if an instance is not restarted due to exhausted retries, this
should be warned, otherwise it's hard to understand why watcher doesn't

Thus this is more geared at developers rather than end users.
The patch:
- adds rules for generating the vcs-version file
- adds a dist-hook for re-generating the file (if possible) and copying
the updated version to the distdir
- modifies devel/upload to re-generate the file before upload
The output of --version will look like:

Convert RPC client to PycURL
Instead of using our custom HTTP client, using PycURL's multi
interface allows us to get rid of the HTTP client threadpool.
The majority of the code is still in the ganeti.http.client
module.
A simple per-thread HTTP client pool gives cURL a chance to
cache and retain as much information as possible (e.g. SSL certs).
Unused HTTP clients (e.g. due to removed nodes) are deleted after
25 requests going through the pool.

Implement lock names for debugging purposes
This patch adds lock names to SharedLocks and LockSets, that can be used
later for displaying the actual locks being held/used in places where we
only have the lock, and not the entire context of the locking operation.
Since I realized that the production code doesn't call LockSet with the
proper members= syntax, but directly as positional parameters, I've
converted this (and the arguments to GlobalLockManager) into positional
