so that they do what they're supposed to
(i.e. enforce resource shares)
- client: change log flag <debt_debug> to <priority_debug>
- client simulator: update REC even with large delta-t.
- client simulator: handle "no new work" apps correctly

of the performance of an app version on a host.
It will then stop using that app version,
so the estimate never has a chance to converge to its correct value.
Fix: multiply by a random factor (mean 1, stddev .1)
when comparing the FLOPS estimates of app versions.

recent estimated credit (REC) instead of debt.
These changes are enabled by
#define USE_REC
in work_fetch.h.
If this is commented out (the default) the client uses
debt-based scheduling, same as before.
TODO: work-fetch policy changes
- client simulator: various fixes:
- compute idle and wasted fraction based on all processing resources,
not just CPU
- compute job completion times based on FLOPS, not CPU seconds
- compute and use project->no_X_apps
etc.

as the major criterion in choosing non-EDF GPU jobs.
GPU scheduling now respects resource share,
and as a result STD should no longer diverge.
- client simulator: various improvements, most notably
that we now generate gnuplot graphs of all debt types
NOTE: the client problem was found and fixed using the simulator!

cmdline arg.
Suppresses the fetch of project list and of current client version #.
Use when running on grid nodes.
- debugging on client simulator. Not done yet.

Insteady of using its own XML input files,
the simulator now takes a client_state.xml file as input.
The simulator generates a synthetic workload based on the
projects, apps, app versions, WUs, and result it finds there.
This means that a user seeing aberrant behavior
can just send their client_state.xml file
and (hopefully) we can use the simulator to repro.
The simulator now can model GPUs.
As of this checkin, the simulator compiles but doesn't work.
There should be no change in the actual client.

- code cleanup: removed include of client/cpp.h from lib/msg_log.cpp.
Stuff in lib/ should NOT include stuff from client/.

if job A is unstarted and EDF,
and there's a job B that is later in the list,
is started, has the same app version,
and has the same arrival time,
move A after B.
- client: remove the "temp_dcf" mechanism,
which had the same goal but didn't work.
- client: in computing overall debt for a project,
subtract a term that reflects pending work.
This should reduce repeated fetches from the same project.
- client simulator: tweaks

These cause problems when "read" is a member name, etc.
Do these #defines, conditioned on _MSC_VER,
in the files that actually need them.
- don't include boinc_win.h from parse.h.

when they're preempting another GPU job.
The problem was as follows:
- job A is chosen to preempt job B
- we tell job B to quit, and initialize job A but don't start it;
however, we set if scheduler state to SCHEDULED
(rather than UNINITIALIZED)
- job B exits, and we start job A.
Since its state is not UNITIALIZED, we don't set up its slot dir.
- job A runs in an empty slot dir, doesn't find its files, and bombs out.
- client: add <slot_debug> option (prints messages about
allocation of slots, creating/removing files in slot dirs).
