10000*major + 100*minor + release,
rather than 100*major + minor.
Sometimes you need release-level resolution.
This affects:
- app_version.min_core_version
- config: min_core_client_version_announced
- config: min_core_client_version
Projects using these must multiply them by 100.

RAM to run job, but when we actually run the job
not enough GPU RAM is free, so the application fails.
This can cause a large number of jobs to fail.
Solution:
- app_plan() can specify the GPU RAM requirements of an app version.
This is passed to the client in a new field
<gpu_ram> of the <app_version> element.
- prior to starting or restarting a GPU app, the client
checks the amount of free RAM on the particular GPU.
If it's not enough for the app version,
the client doesn't start it,
and arranges for the scheduler to ignore it for 5 minutes
(by which point there might be more free GPU RAM)
Notes:
1) this change will have effect only when
both client and scheduler are updated.
2) the check is done in enforce_schedule(),
rather than schedule_cpus(),
because only at that point
have we assigned a specific GPU to the job.
3) there's another case to deal with:
a GPU app's malloc of GPU RAM fails in the middle of the job.
Currently the job fails.
I plan to add an API call boinc_temporary_exit(x) so
that the job can exit and potentially restart in x seconds.
(In principle this mechanism is sufficient for all cases,
but it could lead to a lot of starting/exiting,
so the current change is worthwhile).

to accept CPU, NVIDIA and ATI jobs.
These prefs are shown only where relevant:
e.g., only for processor types for which the project has app versions,
and if it has versions for only one type, no pref is shown.
These prefs affect both client and scheduler.
The client won't ask for work for a device blocked by prefs,
and the scheduler won't send it.
This replaces earlier optional project-specific prefs for
"no CPU jobs" and "no GPU jobs".
(However, these prefs continue to be honored on the server side).
- client: if NVIDIA driver is unknown, say that rather than 0

e.g. the Milkyway@home ATI app, of which we can typically run
2 or 3 instances at once on a GPU.
Changes include:
- In APP_VERSION, don't use a COPROCS to represent the GPU
requirements; just use doubles ncudas and natis.
- sufficient_coprocs() etc. are no longer members of COPROCS
- in HOST_USAGE, ncudas and natis are doubles
- in scheduler request, req_instances is now a double
This checkin doesn't include the job scheduling logic,
i.e. assigning jobs to GPUs. That will follow.

don't modify user preferences or CPID.
- client: fix bug that shows ATI version incorrectly
- database: host.posts has been repurposed as a salt (or seqno)
for a new type of weak authenticator that won't depend on password
- web code:
modify forum_preferences.posts instead of host.posts.
(actually, the former isn't used either, we just do a select count(*);
should fix this at some point).
