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.

- back-end programs: remove hardwired assumptions about

E.g., daemons look for it in "..", others expect it in current dir.
New approach: all the programs look for the project dir as follows:
1) the environment var BOINC_PROJECT_DIR, if defined
2) the current dir, if config.xml is there.
3) else ".."
This means you can run programs in either proj/bin/ or proj/,
or (using BOINC_PROJECT_DIR) you can keep executables

Otherwise, if an app version has a platform different from
the client's primary platform, the client won't find it.
svn path=/trunk/boinc/; revision=17508
Old: although the request message contained all info
about the app version (flops, coproc usage etc.)
the server ignored this info,
and assumed that all anonymous platform apps where CPU.
With 6.6 client, this could produce infinite work fetch:
- client uses anon platform, has coproc app
- client has idle CPU, requests CPU work
- scheduler sends it jobs, thinking they will be done by CPU app
- client asks for more work etc.
New: scheduler parses full info on anon platform app versions:
plan class, FLOPS, coprocs.
It uses this info to make scheduling decisions;
in particular, if the request is for CUDA work,
if will only send jobs that use a CUDA app version.
The <result> records it returns contain info
(plan_class) that tells the client which app_version to use.
This will work correctly even if the client has multiple app versions
for the same app (e.g., a CPU version and a GPU version)

when to do a scheduler RPC:
if user request or acct mgr request, ignore backoff and suspend via GUI;

Otherwise we'll get stuck in a loop where the client asks for CPU work,
and the scheduler sends jobs for what it thinks is a CPU app
but is actually a coproc app.
Eventually we should add coproc info to the app descriptions
send in scheduler request,
so that you can use anonymous platform for coproc apps.
But let's wait on this.

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.

in scheduler request messages, without checking its contents.
One user had apparently edited global_prefs.xml with an XML editor;
it had an <?xml tag at the start,
and had been collapsed into a single line with no newlines,
and no newline at the end.
This caused all scheduler requests from that client to get
"Incomplete request" responses.
The long-term fix is for the client to verify global_prefs.xml,
and for the scheduler to parse it with XML_PARSER.
As a short-term fix, I made these changes:
- If the scheduler reads a line that's too long, it ignores it.
- The scheduler ignores <?xml

mostly so that the parse function could assume
that everything was initially zero.
However, various back-end functions pass around SCHED_CONFIG&
as an argument (also named "config").
This creates a shadow, which is always bad.
Worse is the possibility that some projects have back-end programs
that have a SCHED_CONFIG variable that's automatic,
and therefore isn't zero initially,
and therefore isn't parsing correctly.
To fix this, I changed the 2 vectors in SCHED_CONFIG into pointers,
and have the parse routine zero the structure.
I was tempted to remove the SCHED_CONFIG& args to back-end functions,
but this would have broken some projects' code.
I did, however, change the name from config to config_loc
to avoid shadowing.
Also fixed various other compiler warnings.
