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.

a modified boinc version.
- Added new header "boinc_fcgi.h" to be used instead of "fcgi_stdio.h".
This header defines I/O functions in the namespace FCGI rather than using
redefined functions the way "fcgi_stdio.h" does. This was causing a lot
of headaches when both <cstdio> and "fcgi_stdio.h" was called. Using
overloaded functions fixes this problem, except when the only difference
between functions is the return type (for example ::fopen() returns FILE*
and FCGI::fopen() returns FCGI_FILE*).
- Fixed some missing "#ifdef _WIN32" blocks in filesys.C

Old: when checking whether an app can be run,
check for sufficient coprocessors relative to
the current coprocessor usage.
Bug: it there are 2 CUDA jobs,
the scheduler will decide to run both.
enforce_scheduler() will only be able to run one,
and the other CPU will be idle.
New: include coprocessor usage (along with RAM and CPUs)
in the check, and do a simulated reservation.
In the above scenario, the scheduler will select
one CUDA app and one non-CUDA app.

libcudart{32,64}.so is bundled with client.
client loads it and if successful calls the device-query functions.
- client, Linux: append the current directory
(i.e., the BOINC data directory) to the LD_LIBRARY_PATH for apps.
This goes after the project dir and the slot dir.
This lets apps link to libcudartX.so.
NOTE: this is not recommended; better to include it with your app.
- client: allow for multiple messages from coproc probing
- fixed indentation in cs_platforms.C

and change the correspending structure field from 64KB to 256KB
(could increase this if needed).
This is needed to handle app versions with lots (> 100) of files
- change LARGE_BLOB_SIZE to BLOB_SIZE a bunch of places
- Change COPROCS from vector<COPROC> to vector<COPROC*>.
Otherwise the right virtual functions of COPROCs don't get called
