* Move the windows_format_error_string function to win_util.cpp, .h instead of it being scattered between util.h and str_util.cpp.
* Convert the Windows error string into UTF8 before allowing it to be used by the caller
* Remove windows_error_string from library
- Win process control (affects API and wrapper):
Since Win doesn't have an API for process suspend/resume,
we were suspending processes by
1) enumerating all the threads in the system (typically several thousand)
2) suspending those belonging to the given process
The problem: for each thread, the code was calling a function
in diagnostics_win.cpp to see if the thread was exempted from suspension.
This check (which is unnecessary anyway if we're suspending another process)
was surrounded by a semaphore acquire/release.
The result: performance problems.
It could take a minute to suspend the threads.
Solution:
1) do the check for exemption only if we're suspending threads
in our own process (i.e. from the API)
2) if we're suspending multiple processes, enumerate the threads
only once, and see if each one belongs to any of the processes
3) have the wrapper elevate itself to normal priority.
Otherwise it can get preempted for long periods,
sometimes in the middle of scanning the threads.
Note: post-9x versions of Win have a process group API that includes suspend/resume.
We'll switch to this soon.
- validator: add some sanity-checking for credit,
to prevent granting 1e38 credit.
max_granted_credit now defaults to the equivalent of 1 TeraFLOP-year.
Instances that exceed this are not counted in the credit
calculation, and a critical-mode log message is written
- wrapper: remove wall_cpu_time; not used anymore

(or at least the last double).
This accommodates a particular application (LAMMPS)
that can only append to this file.

i.e. those that create subprocesses.
Previously, the client's job control options (suspend/resume/quit)
would not work for subprocesses.
Multiprocess apps must initialize with something like:
BOINC_OPTIONS options;
boinc_options_defaults(options);
options.multi_process = true;
boinc_init_options(&options);
Note: an application can be both multi-thread and multi-process.
In this case set options.multi_thread as well.
- wrapper: add support for multi-process apps.
Previously, suspend/resume operations did not work for subprocesses.
If a task is multi-process, you must include
<multi_process>1</multi_process>
in its descriptor.

Not necessary.
- wrapper: add optional <append_cmdline_args/> element to
task descriptor.
If set, pass the wrapper's cmdline args to that task.
NOTE: previously they were always passed.
If you want this behavior, you now must set this.

A task descriptor may contain <daemon>.
Daemons are started before regular tasks,
run concurrently with them, and are killed on exit.
