other than work fetch (e.g., user request, project request)
temporarily clear resource backoffs while deciding
whether to request work.
The backoffs are there only to delay RPCs,
and we're going an RPC anyway.

to ask for work inappropriately,
and tell user that it wasn't asking for work.
Here's what was going on:
There are two different structures with work request fields
(req_secs, req_instances, estimated_delay):
COPROC_CUDA *coproc_cuda
and
RSC_WORK_FETCH cuda_work_fetch.
WORK_FETCH::choose_project() copied from cuda_work_fetch to coproc_cuda,
but only if a project was selected.
WORK_FETCH::clear_request() clears cuda_work_fetch but not coproc_cuda.
Scenario:
- a scheduler op is made to project A requesting X>0 secs of CUDA
- later, a scheduler op is made to project B for reason
other than work fetch (e.g., user request)
- choose_project() doesn't choose anything,
so the value of coproc_cuda->req_secs remains X
- clear_request() is called but that doesn't change *coproc_cuda
Solution: work-fetch code no longer knows about internals of
COPROC_CUDA and is not responsible for settings its request fields.
The copying of request fields from RSC_WORK_FETCH to COPROC
is done at a higher level,
in CLIENT_STATE::make_scheduler_request()
Additional bug fix: estimated_delay wasn't being cleared in some cases.

- client: don't do an RPC until we've done CPU benchmarks.
We need the benchmark values to fill in app_version.flops

and a 2nd GPU job with an earlier deadline arrives,
neither job is executed ever.
Reorganized things so that scheduling of GPU jobs is
done independently of CPU jobs.
The policy for GPU jobs:
- always EDF
- jobs are always removed from memory, regardless of checkpoint
(GPU memory is not paged, so it's bad to leave an idle app in memory)
svn path=/trunk/boinc/; revision=17402
- client: abort runaway jobs based on elapsed time instead of CPU time.
Specifically, abort jobs for which
elapsed time > WU.rsc_fpops_bound / app_version.flops
This policy works for
1) GPU jobs (which may use little CPU time)
2) jobs that run but because of bugs use little CPU time
(e.g., because they're sleeping)
whereas the old policy didn't.

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.

(it wasn't setting the "use_XXX" flags). Fixes#776
- client: you can now include a <proxy_info> element
in your cc_config.xml options.
TODO: the whole proxy info thing needs an overhaul:
- no separate "use_XXX" flags;
non-empty http_server_name implies using HTTP proxy, etc.
- merge PROXY_INFO and GR_PROXY_INFO classes
- use XML_PARSER for parsing
- no PROXY_INFO element in HTTP_OP; just use gstate.proxy_info

- WINSCR: Get rid of the 'Up to 5 second wait' for the data thread
to terminate. Force terminate the thread and clean up the
graphics app in a clean-up routine. Forcing the user to wait
when they return to the system isn't a good idea.
- WINSCR: Fix screensaver issue where the screensaver locks up
when the graphics application deadlocks for one reason or
another.
Create two new threads:
1. Monitor system for keyboard and mouse events.
2. Shuffle window z-order positions if needed.
The keyboard/mouse event monitor is isolated from either
the core client getting stuck in a loop and not returning
the results of an RPC or the window shuffling code which
can get stuck if the graphics application dead locks.
The window shuffle code is isolated due to the
BroadcastSystemMessage() API using something akin to
SendMessage() which waits for a return value from the
target windows winproc. If a graphics application
deadlocks for one reason or another it'll cause
the thread to stall. This isn't terminal and so we
just wait for the next time the data thread chooses
a new application and terminates the old one which
will cause the thread to resume.
This should resolve all outstanding issues with the
screensaver not exiting when the mouse or keyboard
is used.

There are situations where multiple projects can legitimately
have large negative LTD on a uniprocessor.

1) if an instance is idle, get work from highest-debt project,
even if it's overworked.
2) if resource has a shortfall, get work from highest-debt
non-overworked project
3) if there's a fetchable non-overworked project with no runnable jobs,
get from from the highest-debt one.
(each step is done first for GPU, then CPU)
Clause 3) is new.
It will cause the client to get jobs for as many projects as possible,
even if there is no shortfall.
This is necessary to make the notion of "overworked" meaningful
(otherwise, any project with long jobs can become overworked).
It also maintains as much variety as possible (like pre-6.6 clients).
Also (small bug fix) if a project is overworked for resource R,
request work for R only in case 1).
svn path=/trunk/boinc/; revision=17327
stop accumulating debt if it's at or around zero.
This prevents other projects from being driven unboundedly negative.
- client: if the number of overworked projects exceeds the number
of device instances, clear debts; this indicates that an earlier
client was buggy and produced bad debt values.
