Added safety features requested by Rom Walton:
* Change COPROC_ATI::get_available_ram and COPROC_NVIDIA::get_available_ram to static routines to prevent calling them without first loading CAL or CUDA libraries.
* Add tests for NULL library calls in these routines.
* Add comments warning about need to call from a separate child process on dual-GPU laptops, proper library initialization, etc.
Some dual-GPU laptops (e.g., Macbook Pro) don't power down the more powerful GPU until all applications which used them exit. To save battery life, the client launches a second instance of the client as a child process to detect and get info about the GPUs.
The child process writes the info to a temp file which our main client then reads.
This option is enabled at compile time by defining USE_CHILD_PROCESS_TO_DETECT_GPUS as non-zero in gpu_detect.cpp
cards. It appears that the Nvidia API was only setting 32-bits
of the 64-bit value. The remaining 32-bits were whatever
was on the stack.

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

and change types of mem-size fields from int to double.
These fields are size_t in NVIDIA's version of this;
however, cuDeviceGetAttribute() returns them as int,
so I don't see where this makes any difference.
- client: fix bug in handling of <no_rsc_apps> element.
- scheduler: message tweaks.
Note: [foo] means that the message is enabled by <debug_foo>.
