(moved coproc_perf() to sched_customize.h to make it available
in plan_class_spec.cpp, and cleaned up includes)

Tells multicore apps how many cores to use.
The --nthreads command line arg to the app is now deprecated
though we'll keep it around for the time being.

to match those in the clGetDeviceInfo() calls.
Principles:
- if there's already a name for something, use it.
- follow case conventions
svn path=/trunk/boinc/; revision=24344
- don't create result records for uploads and downloads.
Just create a msg_to_client record.
- the scheduler handles file-transfer results specially;
it makes a vector of them, then calls a project-supplied function
handle_file_xfer_results()
- change the interface and implementation of put_file and get_file
- client write project sched priority in GUI RPC replies,
but not to the state file

Old: various redundant and/or misleading messages were sent.
New:
- if host w/ no GPU contacts a GPU-only project,
send high-pri message saying they need a GPU
- if host w/ GPU has driver too old for all versions,
send high-pri message saying to update driver
- if host w/ GPU has driver too old for some versions,
send low-pri message saying to update driver
- if host has GPU but too little RAM for any app,
send low-pri message saying so
- scheduler: revamp GPU plan class functions

RAM to run job, but when we actually run the job
not enough GPU RAM is free, so the application fails.
This can cause a large number of jobs to fail.
Solution:
- app_plan() can specify the GPU RAM requirements of an app version.
This is passed to the client in a new field
<gpu_ram> of the <app_version> element.
- prior to starting or restarting a GPU app, the client
checks the amount of free RAM on the particular GPU.
If it's not enough for the app version,
the client doesn't start it,
and arranges for the scheduler to ignore it for 5 minutes
(by which point there might be more free GPU RAM)
Notes:
1) this change will have effect only when
both client and scheduler are updated.
2) the check is done in enforce_schedule(),
rather than schedule_cpus(),
because only at that point
have we assigned a specific GPU to the job.
3) there's another case to deal with:
a GPU app's malloc of GPU RAM fails in the middle of the job.
Currently the job fails.
I plan to add an API call boinc_temporary_exit(x) so
that the job can exit and potentially restart in x seconds.
(In principle this mechanism is sufficient for all cases,
but it could lead to a lot of starting/exiting,
so the current change is worthwhile).

feature without requiring use of score-based scheduling.
So add a new customizable function, wu_is_infeasible_custom(),
where projects can put job-specific checks.
Also, move customizable functions (of which there are now 4)
to a new file, sched_customize.cpp.
