After finding the "most capable" GPU,
ignore FLOPS in deciding what GPUs are equivalent to it.
This opens up the possibility that the client will get jobs
that it won't be able to finish in time.
But it still avoids getting jobs that will crash.

old: find fastest GPU, and pretend that others are the same.
Problem: other GPUs might be less capable,
and not able to handle jobs sent by server.
new: find the most "capable" GPU, use others that are equivalent,
don't use those that are not.
"Capable" is defined by
- compute capability (i.e., hardware version)
- driver version
- memory size
- FLOPs
in that priority order.
See comments in lib/coproc.h

(say what kind of job and why we're scheduling it)
- client: log messages describing GPUs: one line per GPU; fixes#879

(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.

which of those files to include
- Modified MAC address check to work on some non-Linux unixes.
(mac_address.cpp)
- Added suggested change to "already attached to project" checking.
(ProjectInfoPage.cpp)
- changed includes of standard c header files to their c++ equivalents
(i.e. replaced <stdio.h> with <cstdio>) for namespace protection.
- replaced "using namespace std;" with more explicit "using std::function" in
several files.
- Fixed bug in checking whether the os is OS/2 and added conditional OS_OS2
to the build environment. (boinc_platform.m4,configure.ac)
- Changed build environment to not use -nostandardlibs unless we are using
G++ and static linkage is specified. (configure.ac)
- Added makefiles and package building files for solaris CSW package manager.
- Fixed bug with attempting to find login name using logname. (configure.ac)
- Added ifdef HAVE_* protection around some include files commonly found in
sys.
- Added support for unified binary for x86_64/i686-pc-solaris.
(cs_platforms.cpp)
- generate_host_cpid() now uses MAC address on non-linux unix.
(hostinfo_network.cpp)
- Macro BOINC_SET_COMPILE_FLAGS now doesn't check gcc only flags on non-gcc
compilers. (boinc_set_compile_flags.m4)
- Library compiles no longer depend upon the library extension or require
the library to be prefixed with lib.
- More fixes for fcgi builds.
- Added declaration of "struct ether_addr" and ether_ntoa(). Have not yet
implemented ether_ntoa() for machines that don't have it, or where it is
buggy. (unix_util.h)
- Added FCGI::perror() which calls FCGI_perror(). (boinc_fcgi.{h,cpp})
- Fixed library Makefiles so that all required headers get installed.

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.

- 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!)

put a textual summary of them in host.serialnum (currently unused)
- web: show coprocs on host detail page
- db_dump: include coproc info in host XML
