Apparently this generates warning messages that fill up log files,
and we may not need it anymore.

namely:
- some download stalled
- some task suspended
- too many uploading tasks

We want to track the product name (e.g. "HTC One X") of Android devices.
On Android, the API to get this is Java,
so we need to do it in the GUI rather than the client.
- Add product_name field to HOST_INFO
- Add a GUI RPC for passing this info from the GUI to the client.
- Store it in client_state.xml, so that the client knows it initially.

The product name is included in scheduler RPC requests, as part of <host_info>.
TODO: add server-side support for parsing it and storing in DB.

Also: move DEVICE_STATUS out of HOST_INFO; it didn't belong there.

  very low angle range (VLAR) results to go to newer AMD/ATI GPUs.

"make install" followed by make_project should now work

These were mistakenly removed

check_set() wasn't returning "retry" properly in the case where
one of the calls to init_result() return ERR_OPEN_DIR
(treated as a transient failure, since it can be caused by a failed NFS mount)

Lets you customize the notice that's generated when a new client version is available

- SCHED: Scheduler was not using properly estimated performance when assigning
  work.  It was using theoretical performance to choose version and actual
  preformance to determine how long it would take.  I've changed that to start
  with theoretical performance and converge to actual performance as
  host_app_version pfc_n increases.
- SCHED: Added some additional app version selection debugging output.
