Right now the timeout is not passed by any caller, making the code
effectively go back to blocking acquires. Since the timeout is always
None, no caller needs to be changed in this patch.

This change also means that any LUXI query handled by ganeti-masterd
will use blocking acquires if they need locks (only the case for getting
tags).

In order to support priorities, the processing of jobs needs to be
changed. Instead of processing jobs as a whole, the code is changed to
process one opcode at a time and then return to the queue. See the
Ganeti 2.3 design document for details.

This patch does not yet use priorities for acquiring locks.

The enclosed unittests increase the test coverage of jqueue.py from
about 34% to 58%. Please note that they also test some parts not added
by this patch, but testing them became only possible with some
infrastructure added by this patch. For the first time, many
implications and assumptions for the job queue are codified in these
unittests.

New KVMs (0.12.1.2-el6 and 0.13.5 tested) exit immediately after
unsuccessful network connection when they are in "-incoming" mode. The
simple check netutils.TcpPing causes remote kvm to exit so the migration
will always fail. This check is also redundant by the way as if the
network port is closed migration will fail with guarantee. This commit
removes this check.
