* update loopback detection to use SIOCGIFFLAGS and IFF_LOOPBACK; add unit tests
* adds a check for the wireserver ip, and if it does exist then skip the dhcp lookup and route manipulation; adds unit tests
* ensure the first selected interface is the primary, which is that with the default route; adds unit tests
* parse the wireserver from the dhcp leases file on disk; distro-specific, this is the ubuntu implementation; adds unit tests
* unit test fixes, python 3 changes
* code review feedback
- correct scvmm references
- add unit tests for scvmm detection
- ensure all matching devices are mounted and examined for scvmm configuration
- exit once vmm startup script is found and executed
- fixes#185
This will treat interface names such as 'lo:1' as loopback
as well. The ultimate solution is to use sysfs+procfs in this
method to check the flags and find the ipv4 addr. However sticking
to an extended check for now.
Fixes#188.
