This decorator can be used to call a function holding with protection
from a given signal. The function should accept a dict of
utils.SignalHandler, indexed by signal number, and make use of it.

utils.SignalHandler can accept either a list of signals or a single

IO is never unregistered in our current usage, so dropping that
functionality for now. Also putting the poller outside of the Run()
function allows us to avoid the double step of adding tuples to an
_io_wait_add queue and adding them later in the main loop.

Timers are currently unused, slightly buggy (for example timeout doesn't

have timeouts in more simple fashion, and is not a mainloop user
anyway.

This patch adds querying of ctime/mtime for the cluster/nodes/instances.

Reviewed-by: Michael Hanselmann <hansmi@google.com>

This patch adds ctime/mtime support to the “main” config objects - the
config data itself, and the cluster/nodes/instances objects.

These are not added on auto-upgrade, but rather should be migrated if it
makes sense when 2.0 is upgraded to 2.1.

(cherry picked from commit 022c3a0b)

Since drained nodes could be (partially or fully) broken in iallocator,
we ignore results from these nodes when building the cluster map in
preparation for sending it to the script.

This is a cheap change for the stable branch; ideally we should not
query them at all.

The patch also fixes a typo in iallocator.rst.
