There are two mechanisms to prevent the scheduler from
sending jobs that won't finish by their deadline.
Simple mechanism:
The client sends the interval x for which CPUs are projected
to be saturated.
Given a job with estimated duration y,
the scheduler doesn't send it if x + y exceeds the delay bound.
If it does send it, x is incremented by y.
Complex mechanism:
Client sends workload description.
Scheduler does EDF simulation, sees if deadlines are missed.
The only project using this AFAIK is BOINC alpha test.
Neither of these mechanisms takes coprocessors into account,
and as a result jobs could be sent that are doomed to
miss their deadline.
This checkin adds coprocessor awareness to the Simple mechanism.
Changes:
Client:
compute estimated delay (i.e. time until non-saturation)
for coprocessors as well as CPU.
Send them in scheduler request as part of coproc descriptor.
Scheduler:
Keep track of estimated delays separately for different resources
- client: fixed bug that computed CPU estimated delay incorrectly
- client: the work request (req_secs) for a resource is the min
of the project's share and the shortfall.

- client: restore notion of overworked;
if a project is overworked for a resource R,
don't fetch work for R unless there are idle instances

but we don't need to send any more CUDA jobs,
delete the BEST_APP_VERSION record and look for another app version.
This lets the scheduler send both CUDA and CPU app versions
for a given app in a single RPC.

1) net adjustment for eligible projects is zero;
2) max LTD is zero
- scheduler: fix msgs so disk size is shown in GB

1) it uses a coprocessor
2) it has checkpointed since the client started
3) it's being preempted because of a user action
(suspend job, project, or all processing)
or user preference (time of day, computer in use)
- scheduler: if shared mem seg doesn't exist,
report it and don't crash
svn path=/trunk/boinc/; revision=16992
even if it doesn't use a coprocessor.
- scheduler: added an "nci" (non CPU intensive) plan class
to sched_plan.cpp. It declares the use of 1% of a CPU.
The above two changes are intended to allow the QCN app to
run at above_idle priority, which it needs in order to do 500Hz polling.
- API: the std::string version of boinc_resolve_filename()
acts the same as the char[] version.

and add <cuda_multiplier>.
The latter is used in calculating max jobs/day for a host;
namely, it's host.max_results_day * (NCPUS + NCUDA*cuda_multiplier).
Set it to 10 or so if you have CUDA apps.
- scheduler: don't overload effective_ncpus();
instead, add two new functions,
max_results_day_multiplier() and max_wus_in_progress_multiplier()
- scheduler: don't reduce max_results_day if we get an aborted job
(it might have been aborted by the project;
not appopriate to punish host in this case)

- Update to libtool 1.5.24
- build environment: Major automake changes that I've been warning about
for some time.
- Now uses libtool to build libraries.
- Builds separate boinc_fcgi and sched_fcgi libraries for use with
FCGI server components.
- New macro "BOINC_CHECK_LIB_WITH" that executes a "AC_CHECK_LIB" on
a library only if --with-libname[=DIR] is specified on the configure
command line. This is to allow inclusion of libraries when the
ssl, gtk, wxWidgets, or other configuration is incorrect for static
libraries.
- Added a lot of "--with-*" for some libraries that might be required for
static builds.
- The sea directory has been moved to packages/generic. Changes to sea
and the associated scripts might be required to better make use of the
staging mechanism and shared libraries.
- Fixed includes of boinc_fcgi.h in many files.
- Fixed places where FCGI_FILE needs to be used implicitly.
- Fixed missing define of _SC_PAGESIZE on hosts that define only
_SC_PAGE_SIZE.
- Moved build of boinc_cmd (and source file) from lib to client

- parse new request message elements
(CPU and coproc requested seconds and instances)
- decide how many jobs to send based on these params
- select app version based on these params
(may send both CPU and CUDA app versions for the same app!)

exceptional cases (e.g., send at least one job to a host with no work)
apply whether using EDF or basic check
- client: don't accept 0 for active/on/connected frac; set to 1

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

- web: show coprocs on host detail page

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.
