Unify fingerprinting aka signature calculation.
...
This fixes https://github.com/prometheus/client_golang/issues/74 .
IT CHANGES THE FINGERPRINTING AND THEREFORE INVALIDATES EACH AND EVERY
PERSISTED FINGERPRINT (I.E. YOU HAVE TO WIPE THE STORAGE TO USE THIS).
This commit removes the LabelValuesToSignature function as it is used
nowhere (and broken in the way it is implemented right now).
Also, remove one more golint warning.

Use godep with import rewriting for vendoring.
...
The new vendoring was produced by running:
godep save -r ./examples/... ./prometheus/... ./text/... ./model/... ./extraction/...
Two things to note:
- "extraction/processor0_0_{1,2}_test.go" imported a package from
"github.com/prometheus/prometheus", all for just one tiny testing
function. To not have to deal with a circular vendoring dependency, I
simply replaced the usage of the function by some in-line logic.
- godep grouped the rewritten imports slightly differently for some
reason, but at least the standard library imports are still in a
separate section. Not sure if it's worth manually keeping our old
import grouping scheme or if we should simply use that godep-generated
one.

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.

As it is expected that the process collector can fail under certain

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

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.
