Fix numerous bigs in the FreeBSD backend

Browse Source 
* Correct calculation of CPU time.
* Fix a bug on newer versions of FreeBSD where computing the process map leads
to a tight error loop.
* Add support for the new procstat API to obtain the list of open files and
cwd.
* Use kvm_openfiles instead of kvm_open to better handle error messages.
* Split some modules out into non-suid modules.
* Properly determine the number of CPUs.
