scheduler: parse <opencl_cpu_prop> in scheduler requests correctly

The OPENCL_CPU_PROP structure was being referred to as both
"opencl_cpu_prop" and "cpu_opencl_prop", roughly 50/50,
in variable names and XML tags.
Let's standardize on "opencl_cpu_prop",
which is what current clients are sending in scheduler requests.

VBOX: Support VirtualBox's new method for network bandwidth throttling.  Use old method for anything older than 4.2.0.
VBOX: If the network throttle value is reset back to 0KB, reset the throttle group bandwidth back to 1024G.
WINBUILD: Update vboxwrappers version to 26043
VBOX: If retrying suspend/resume commands fail, call boinc_temporary_exit() and reschedule after 5 minutes.

BOINC should terminate the VM process and resume from snapshot the next time the task is started.

VBOX: Do not display an error if the remove bandwidth group fails because it has already been removed.
VBOX: Only check to see if it is a session lock error if retval is greater than zero.
WINBUILD: Update vboxwrappers version to 26045
WINBUILD: Remove ipch stuff
 Client and Manager: make notices translatable

- Add a GUI RPC ("set_language") that lets the Manager communicate
  the user's selected language code to the client at startup.
- The client stores the language code in the client state file
- The client appends a "lang=X" GET argument to the URLs from
  which notices are fetched.
- The next steps (not done) are 1) to change the get_notices.php
  script to parse the argument and do translation, and
  2) extend our Pootle system to allow volunteer translation
  of notices by all projects.
