Update protobuf library package name.
...
The Golang protocol buffer library has now moved to GitHub:
https://github.com/golang/protobuf
Although "go get"-ing the old package name still works, moving
everything to the new one will make vendoring cleaner.

Handle process collector errors gracefully
...
As it is expected that the process collector can fail under certain
conditions (proc information for a process only readable by root or
other user for example) and as there is currently no option to configure
the error behavior of the client, this change reverts the error
reporting introduced in 159e96f
. This effectively means that errors are
simply ignored and there won't be any samples for the process_* metrics
in case of an error.
Once a user can control how to behave in case of errors returned by
collectors, this change should probably be reverted.

Remove dependency on procfs/cgo in non-procfs systems

The procfs package has a cgo dependency (necessary to calculate system
times). As procfs is not available under windows, darwin and supposely
all newer BSD systems, this change remove the procfs dependency on these
systems.

Use clear error interface for process pidFn
...
If a given pidFn for a process collector can't determine the pid, this
had to be signaled with an invalid pid so far (pid <= 0). In order to
make the error interface clearer for users, this change introduces an
explicit error parameter.
