should warn if repo.fossology.org not available

[Kyle Nitzsche]

By default, repo.fossology.org is the fossology server queried for all copyright files that are not valid dep5.

User can specify another seriver with -f <IP> args on getlicenses.py.

With getlicenses 1.1, there is no warning to the user that the fossology server is unavailable. Instead the process simply completes but most packages have no licenses found.

User should be warned if the fossology server is not accessible and be given the option of halting.

fix released in pkg 1.2

[Kyle Nitzsche (knitzsche)]

Current fix successfully checks IP level connectivity to designated fossology server machine with ping. but even if ping succeeds, fossology server itself may not be responsive (for example apache may not be configured correctly or started, etc).

reopening.

[Kyle Nitzsche (knitzsche)]

Now use wget to test accessibility of fossology server instead of ping. wget is the interface through which the copyright files are submitted for analysis, so this is the proper test.
