but checks for the "stop_daemons" trigger file every 1 sec.
Use this instead of sleep() in daemons.
This will speed up bin/stop.

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

This now supports two main use cases:
1) there's a job that you want to run once on all hosts,
present and future
(or all hosts belonging to a user, or to a team).
The job is never transitioned, validated, or assimilated.
2) There's a normal job for which you want to use only
hosts belonging to a specific user (e.g. cluster or cloud hosts).
This restriction can be made either when the job is created,
or on the fly,
e.g. as part of a scheme for accelerating batch completion.
For the latter purposes we now provide a function
restrict_wu_to_user(DB_WORKUNIT&, int userid);
The job goes through the standard
transitioner/validator/assimilator path.
These cases are enabled by config flags
<enable_assignment_multi/>
<enable_assignment/>
respectively.
Assignment of type 2) are no longer stored in shared mem,
so there is no limit on their number.
There is no longer a rule that assigned job names must contain "asgn".
NOTE: this requires a database update.

Some credit cheats (e.g. with credit_by_runtime) can be done
by reporting a huge value.
Fix this by capping the value at 1.1 times the 95th percentile
of host.p_fpops, taken over active hosts.

Tells multicore apps how many cores to use.
The --nthreads command line arg to the app is now deprecated
though we'll keep it around for the time being.

- daily quota mechanism
- reliable mechanism (accelerated retries)
- "trusted" mechanism (adaptive replication)
- scheduler: enforce host scale probation only for apps with
host_scale_check set.
- validator: do scale probation on invalid results
(need this in addition to error and timeout cases)
- feeder: update app version scales every 10 min, not 10 sec
- back-end apps: support --foo as well as -foo for options
Notes:
- If you have, say, cuda, cuda23 and cuda_fermi plan classes,
a host will have separate quotas for each one.
That means it could error out on 100 jobs for cuda_fermi,
and when its quota goes to zero,
error out on 100 jobs for cuda23, etc.
This is intentional; there may be cases where one version
works but not the others.
- host.error_rate and host.max_results_day are deprecated
TODO:
- the values in the app table for limits on jobs in progress etc.
should override rather than config.xml.
Implementation notes:
scheduler:
process_request():
read all host_app_versions for host at start;
Compute "reliable" and "trusted" for each one.
write modified records at end
get_app_version():
add "reliable_only" arg; if set, use only reliable versions
skip over-quota versions
Multi-pass scheduling: if have at least one reliable version,
do a pass for jobs that need reliable,
and use only reliable versions.
Then clear best_app_versions cache.
Score-based scheduling: for need-reliable jobs,
it will pick the fastest version,
then give a score bonus if that version happens to be reliable.
When get back a successful result from client:
increase daily quota
When get back an error result from client:
impose scale probation
decrease daily quota if not aborted
Validator:
when handling a WU, create a vector of HOST_APP_VERSION
parallel to vector of RESULT.
Pass it to assign_credit_set().
Make copies of originals so we can update only modified ones
update HOST_APP_VERSION error rates
Transitioner:
decrease quota on timeout

- client (Unix): if client crashes while benchmark processes are going,
make sure they detect this and exit.
- back-end programs: remove hardwired assumptions about
what directory they run in, and hence where config.xml is.
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
outside of the project dir.

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.
- scheduler: compile fix for gcc 4.4. Fixes#854
svn path=/trunk/boinc/; revision=17502
which of those files to include
- Modified MAC address check to work on some non-Linux unixes.
(mac_address.cpp)
- Added suggested change to "already attached to project" checking.
(ProjectInfoPage.cpp)
- changed includes of standard c header files to their c++ equivalents
(i.e. replaced <stdio.h> with <cstdio>) for namespace protection.
- replaced "using namespace std;" with more explicit "using std::function" in
several files.
- Fixed bug in checking whether the os is OS/2 and added conditional OS_OS2
to the build environment. (boinc_platform.m4,configure.ac)
- Changed build environment to not use -nostandardlibs unless we are using
G++ and static linkage is specified. (configure.ac)
- Added makefiles and package building files for solaris CSW package manager.
- Fixed bug with attempting to find login name using logname. (configure.ac)
- Added ifdef HAVE_* protection around some include files commonly found in
sys.
- Added support for unified binary for x86_64/i686-pc-solaris.
(cs_platforms.cpp)
- generate_host_cpid() now uses MAC address on non-linux unix.
(hostinfo_network.cpp)
- Macro BOINC_SET_COMPILE_FLAGS now doesn't check gcc only flags on non-gcc
compilers. (boinc_set_compile_flags.m4)
- Library compiles no longer depend upon the library extension or require
the library to be prefixed with lib.
- More fixes for fcgi builds.
- Added declaration of "struct ether_addr" and ether_ntoa(). Have not yet
implemented ether_ntoa() for machines that don't have it, or where it is
buggy. (unix_util.h)
- Added FCGI::perror() which calls FCGI_perror(). (boinc_fcgi.{h,cpp})
- Fixed library Makefiles so that all required headers get installed.
