Old: heartbeat mechanism
Problem: if the client is blocked for > 30 secs
(e.g. because it takes a long time to write the state file,
of because it's stopped in a debugger)
then apps exit.
This is bad is the app doesn't checkpoint and has been
running for a long time.
New: the client passes its PID to the app.
The app periodically (10 sec) checks that the process still exists.
Notes:
- For backward compatibility (e.g. new API w/ old client,
or vice versa) the client still sends heartbeats,
and the API checks heartbeats if the client doesn't pass a PID.
- The new mechanism works only if the client's PID isn't assigned
to a new process within 10 secs of the client exiting.
Windows 2000 reuses PIDs immediately, so check for Win2K
and don't use this mechanism if so.
TODO: For Unix multithread apps,
critical sections aren't currently being enforced.
Need to fix this by masking signals.

clear the suspend_request flag.
Otherwise we'll end up doing two suspends,
and on Win the app will be suspended forever.

Lets application specify a min checkpoint interval.
The actual min checkpoint interval is the max of this
and the user-specified pref for min disk interval.

CODING STYLE LAW (minimal inclusion principle):
If foo.cpp requires <blah.h>,
#include <blah.h> in foo.cpp, NOT foo.h

moved app_ipc.h inclusion outside __cplusplus
since it contains important C mode prototypes
(boinc_resolve_filename() etc.)

lets an application report its network usage to BOINC,
and hence take it into account with monthly limits etc.
- API: get rid of deprecated boinc_ops_per_cpu_sec(),
boinc_ops_cumulative(), and
boinc_set_credit_claim();
- admin web: update manage_apps.php;
add the ability to set homogeneous app version

and it timed out and we killed it, we'd treat it as a job error.
(This was a major bug).
- API: remove BOINC_STATUS::suspend_request.
I meant to do this before.

and display it there and in the log.

allow applications to supply a "web graphics URL",
in which case the manager's "Show Graphics" button
opens a browser at that URL.
This typically would used for applications that
implement a web server that serves pages showing
job information in HTML.
- vboxwrapper: if <pf_guest_port> is specified in the config file,
set up port forwarding to that port
and use the above API call with URL "http://localhost:port"

reduce its runtime from O(N^2) to O(N),
where N is the number of runnable jobs
(which can be in the thousands).
This will make the client emulator run a lot faster,
and will reduce the client CPU overhead a bit.
- API: change boinc_get_opencl_ids() so that it returns
a BOINC error code (< -100) if the app_init.xml is
missing or bad (i.e. we're running standalone),
and an OpenCL error code (> -100) if an OpenCL call failed.
