checkpointing: detect if system is able to checkpoint during deployment

[GoogleCodeExporter]

during runtime.

if not, throw error at user/syslog

if user requests checkpointing and system does not have the capability, throw 
error at user/syslog

installation script:
* check if library exists

res/mbatchd:
* see if library is able to handle our requirements.

performance: detect in under 5-6 seconds?

security: 
* SELinux permissions at specified path
* ACLs at specified path (see if everybody/who is capable of reading/writing) 
and only them
