Add a luxi call for multi-job submit
As a workaround for the job submit timeouts that we have, this patch
adds a new luxi call for multi-job submit; the advantage is that all the
jobs are added in the queue and only after the workers can start
processing them.
This is definitely faster than per-job submit, where the submission of
new jobs competes with the workers processing jobs.
On a pure no-op OpDelay opcode (not on master, not on nodes), we have:
- 100 jobs:
- individual: submit time ~21s, processing time ~21s
- multiple: submit time 7-9s, processing time ~22s
- 250 jobs:
- individual: submit time ~56s, processing time ~57s
run 2: ~54s ~55s
- multiple: submit time ~20s, processing time ~51s
run 2: ~17s ~52s
which shows that we indeed gain on the client side, and maybe even on
the total processing time for a high number of jobs. For just 10 or so I
expect the difference to be just noise.
This will probably require increasing the timeout a little when
submitting too many jobs - 250 jobs at ~20 seconds is close to the
current rw timeout of 60s.

Move to data-based hvparam checks instead of code
Currently the hypervisor parameters are checked using hard-coded snippets in
each hypervisor. However, most parameter checks fall into three cases:
- file check
- directory check
- string value in a set
And the remaining ones are checked using simple functions.
This patch moves to a declarative-style for these parameter checks; in
hv_base we add the necessary infrastructure for these checks, and the
above common cases.
This translates into complete removal of the Check/Verify functions for
the Xen hypervisors, and a drastic reduction for the KVM one (which has
inter-parameter dependencies and thus can't use a simple table).

watcher: try to restart the master if down
Bugs in either our code or in associated libraries can bring the master daemon
down, and this (due to the 2.0 architecture) stops all work on the cluster.
Since the watcher already does periodic checks on the cluster, we modify
it to try to start the master automatically in case of failures to
connect. This will be tried only once per cycle.
Also, in this case, we modify the code so that the watcher status file
is not updated - its timestamp will reflect thus the time of last
successful connection to the master.
Side note: the except errors.ConfigurationError part could be cleaned
up, since in 2.0 we don't usually get that directly, and if we do it's
an error and we shouldn't touch the file anyway; but that is not a rc5
change.

Different from 1.2, where only the kernel arguments were supporting

This is much more flexible, and allows for example:
- start with different, temporary kernel
- start with different memory size

The docs will be stored under doc/html and the build system also need an

maintainer-related objects and are removed at maintainer-clean time.

Convert from auto-generated RAPI docs to static
This patch removes the autogeneration of the RAPI docs from the code
(based on docstrings) and moves the current autogenerated output to
the rapi.rst file.
The reasons behind this are multiple:
- the build system becomes a little more simple (this could have been
achieved also by distributing the built documentation, though)
- it's hard to actually write documentation in docstrings; you have to
fit restructured text inside the docstrings, and this results in
not really nice output
- even by being close to the code, the documentation manages to get
out of sync (not paying attention to docstrings)
This will also help with the move to sphinx.
