- 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.
