The SETI@home result table is about to run out of 32-bit IDs,
so we need to move to 64-bit result IDs.
This will happen to the workunit table at some point too.
I changed the server C++ code to use the "long" type for all DB IDs
(and to use appropriate conversion codes like %lu).
"long" is 64 bit on 64-bit machines.
For uniformity I did this for all tables,
even ones (like app) that will never get big.
I chose NOT to change the DB schema for now.
The new code will work with 32-bit ID fields in the DB.
As projects approach the 32-bit limit on a table they can change
its ID field, and fields that reference this table, to BIGINT.
This is likely to happen only on the result and workunit tables.
I put functions in html/ops/db_update.php
to change the IDs of these tables.
- add a config item vda_host_timeout.
A host that hasn't done a scheduler RPC for this long
is considered dead.
- a host that's not running a version 7+ client is considered dead
- host.cpu_efficiency (an otherwise unused field) is used
as a flag for dead hosts
- the scheduler clears the flag if the client is v7+
- vdad sets the flag for hosts where last RPC is old
- before choosing a host for chunk download,
vdad checks its client version.

- Allow projects to report "desired disk usage" (DDU).
If the client learns that a project wants disk space,
it can shrink the allocation to other projects.
- Base share computation on DDU rather than disk usage.
- Introduce the notion of "disk resource share".
This is defined (somewhat arbitrarily) as resource share
plus 1/10 of the largest resource share.
This is intended to ensure that even zero-share projects
get enough disk space to store app versions and data files;
otherwise they wouldn't be able to compute.
- server: use host.d_boinc_max (which wasn't being used)
to start d_project_share reported by client.
- volunteer storage: change the way hosts are allocated to chunks.
Allow hosts to store several chunks of the same file, if needed

initial work request to a project
- client: put some casts to double in NVIDIA detect code.
Shouldn't make any difference.
- volunteer storage: truncate file to right size after retrieval

while writing to them.
It's not clear to me that this locking is beneficial,
and it may be causing filesystem problems at WCG
- volunteer storage stuff

file_deleter.cpp into a separate program,
since it blocks normal file deletion while it's running.
From Bernd.
- storage stuff
svn path=/trunk/boinc/; revision=25321
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
