Old:
1) check deadline based on wu.delay_bound
2) in add_result_to_reply(), potentially modify wu.delay_bound,
e.g. because of retry acceleration
problem: reducing delay bound may cause deadline miss
New:
1) new function get_delay_bound_range()
(called from wu_is_infeasible_fast())
returns optimistic and pessimistic delay bounds.
Retry acceleration logic is here.
2) check deadline based on optimistic bound;
if that fails, check based on pessimistic bound.
Set wu.delay_bound to the one that worked.
Notes:
- get_delay_bound_range() needs result priority and report deadline,
and it's called before we read the full result.
So add these items to WORK_ITEM and WU_RESULT.
- get_delay_bound_range() could be customized for
project-specific deadline policy.
- add_result_to_reply() was becoming a toxic waste dump.
Deadline-related stuff should have been factored out in any case.

The limit on jobs in progress is now
max_wus_in_progress * NCPUS
+ max_wus_in_progress * NGPUS
where NCPUS and NGPUS reflect prefs and are capped.
Furthermore: if the client reports plan class for in-progress jobs
(see checkin of 31 May 2009)
then these limits are enforced separately;
i.e. the # of in-progress CPU jobs is <= max_wus_in_progress*NCPUS,
and the # of in-progress GPU jobs is <= max_wus_in_progress_gpu*NGPUS
- scheduler config: rename <cuda_multiplier> to <gpu_multiplier>
- scheduler: <max_wus_to_send> is now scaled by
(NCPUS + gpu_multiplier*NGPUS)
- scheduler: don't keep scanning array if !work_needed()
- scheduler: moved array-scan logic from sched_send.cpp to sched_array.cpp
- scheduler: don't say "no work available" if jobs are available
but work_needed() is initially false

(app versions don't have a <coprocs> around coproc elements,
may an oversight but let's stick with it).
Anyway, I think it's working now.
- lib: remove "owner" array from COPROC.
This was used in client to keep track of assignment of
coprocessors to tasks, but we got rid of the reserve/free scheme.
NOTE: this breaks the mechanism for passing --device N to apps;
I'll have to do this another way. Stay tuned.

- web: check whether to show profile in separate function
from displaying profile; eliminate double headers
- scheduler: finish purge of redundant arguments

for the selected APP_VERSION, rather than on the CPU benchmarks.
Otherwise estimates are wrong for GPU or multi-thread apps.
- scheduler: start switching from having SCHED_REQUEST and
SCHED_REPLY as globals instead of passing them around as args;
to be continued.
svn path=/trunk/boinc/; revision=16691
- scheduler: fix egregious bug where wu_is_infeasible_fast() result
is ignored, and we send jobs to hosts that can't handle them.
- scheduler: don't check for disk space in work_needed();
do it in check_disk(), which generates a message to user.
- scheduler: add -debug_log flag, which sends stderr to
"debug_log" rather than scheduler_log.txt (for debugging)

If set the "effective NCPUS" (which is used to scale
daily_result_quota and max_wus_in_progress)
is max'd with the # of CUDA GPUs.
