Lets SCHED_MSG_LOG be used including only -lboinc, not -lsched.
This is a tactical move; SETI@home back-end code
uses SCHED_MSG_LOG and I need to make this work without -lsched,
which pulls in MySQL libraries which I don't want.
Old: if the timer thread gets a <suspend> message while we're in
a critical section, it sets a "suspend_request" flag.
The timer then periodically (10X/sec) checks whether
suspend_request is set and we're no longer in a critical section;
if so it suspends the worker thread.
Problem (pointed out by Oliver): this doesn't work if the worker thread
is almost always in a critical section
(as is the case for GPU apps, which treat GPU kernels as critical sections).
The app never gets suspended.
New:
1) boinc_end_critical_section() checks suspend_request;
if set, it calls suspend_activities()
2) On Unix, if suspend_activities() is called from the worker thread,
it calls sleep() in a loop until the suspension is over.
(Note: pthreads has no suspend/resume).
3) Add a mutex to protect the data structures shared between
the timer and worker threads.
Oliver pointed out that
use strcat instead
- client: don't use get_mac_address() to create host CPIDs
(we have plenty of other info to make them unique)
- storage stuff

Note: XML_PARSER::parse_str() doesn't currently work right
for something like <foo><a>xx</a></foo>.
It should return "<a>xx</a>".

Win: enumerate all descendants, and kill them all TerminateProcess().
Unix:
send the main process a SIGTERM.
Check once a sec for existence of descendants.
if none, done
If any still exist after 10 sec, kill all descendants

Projects will need to update DB and recompile all back-end programs.
Summary:
- new way of computing credit
- "reliable host" mechanism is per app version
- "host punishment" mechanism is per app version
- adjustment of wu.rsc_fpops_est provides the
equivalent of per app version DCF
- max jobs in progress is now per app
- max jobs per RPC is now per app
TODO:
- reliable mechanism:
- populate and use host_app_version.error_rate
- populate host_app_version.turnaround
- host punishment:
- populate host_app_version.max_jobs_per_day
- populate host_app_version.n_jobs_today
- use app.max_jobs_per_day_init
- job limits:
- use app.max_jobs_in_progress, max_gpu_jobs_in_progress
- use app.max_jobs_per_rpc
- adjust wu.rsc_fpops_est
- remove old credit stuff
fpops_cumulative, credit_multiplier
credit computation in scheduler
- AVERAGE class: use the Knuth algorithm (Wikipedia)

Triggering the work generator is now done via the DB
instead of flat files.
Since only E@h uses locality scheduling,
I kept the DB changes in a separate file (db/schema_locality.sql).
There's a new field in the workunit table,
and that's a required update (in db_update.php)
- manager: compile fix
