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.

of the full 2 CPUs. Vboxwrapper uses ceil() to allocate enough
whole CPUs for Virtualbox. Ideally this will cause the BOINC
client-side scheduler to use the remaining fraction of the CPU
for GPU data transfer which will then free up one whole CPU for
another job. All without over-commiting anything.

If found, set HOST_INFO::p_vm_extensions_disabled,
and pass this to the scheduler.
- scheduler (VBox app plan function) if a host has p_vm_extensions_disabled
set, don't sent it multicore VBox jobs.
Note: if you have a host with VM extensions, and they're disabled
in the BIOS, and you enable them, you can remove the
<p_vm_extensions_disabled> line from client_state.xml
and you'll be eligible to get multicore VM jobs again.

- client: msg tweak

- scheduler: in computing HOST_USAGE::project_flops for a job,
if we don't have sufficient elapsed_time statistics
for either the (host, app_version) or the app_version,
use a conservative estimate (p_fpops*(#cpus+#ngpus))
rather than the number returned by app_plan().
This avoids "time limit exceeded" errors when the latter is way off.

In the inner loop of scan_work_array() there are two WORKUNITs:
- the one that's part of wu_result (in the shared-mem array)
- a temp copy.
quick_check() may modify this in host-specific ways
(e.g., adjusting rsc_fpops_est or delay_bound).
This is the one we pass to add_result_to_reply().
When we reread hr_class and app_version_id from the DB,
update both structs.

(reported by Kevin Reed).
The problem: cache inconsistency.
If there are 2 results for the same WU in shared mem,
and 2 scheduler instances get them around the same time,
they can send them with different app versions.
We already fixed this problem for HR by
1) rereading the relevant WU fields while deciding
whether to send the result
2) doing a "careful update" of the WU field using a where clause
to make sure it wasn't modified in the (short) interval
since rereading it.
I fixed the HAV problem in the same way,
and merged the two mechanisms to combine the DB queries.
Also:
- The rereads are done in slow_check() (see below).
- The careful updates are done in update_wu_on_send(),
and this is called *before* doing careful updates on result fields.
That way, if the WU updates fail, we don't have orphaned results.
- already_sent_to_different_platform_careful() (sic)
no longer does DB stuff, so it's merged with
already_send_to_different_hr_class() (better name)
NOTE: slow_check() is used in array scheduling only.
Score-based scheduling uses other code,
in which this bug is not yet fixed.
Locality scheduling doesn't support HR or HAV at all.
This should be unified.

The problem: the choice of app version was based on
the "projected FLOPS" return by estimate_flops(av).
If usage stats exist for the host / app version,
this returns a number X such that
WU.rsc_fpops_est/X approximates the runtime of a job
using the given app version..
(If WU.rsc_fpops_est is way off, this will be correspondingly way off
from the actual FLOPS the app version will get.)
However, if there are no usage stats,
it return an estimate based on host hardware speed,
which might be 100X less.
Hence, in some cases a new app version would never get used.
Solution: choose app versions based on the values
returned by the app plan functions.
Use estimate_flops() AFTER choosing the version.
- scheduler: improve the accuracy of FLOPS estimation for GPU apps.
The "flops_scale" argument to coproc_perf
(which expresses the difference between peak GPU FLOPS
and actual FLOPS) should be used to scale GPU FLOPS
prior to calling coproc_perf(),
rather than scaling the estimate returned by coproc_perf().

the boundary between days is 00:00 in server local time.
This creates a spike of jobs being dispatched
(and files being downloaded) after that time.
Solution: distribute the boundary uniformly,
using a random number determined by the host ID.
(Make sure to save/restore the seed around this,
so we don't destroy the randomness of other things)
