Add licenses of vendored code left out by godep.
...
As it looks, `godep update ...` will preserve the files.
Obviously, if you blow away everything and run a `godep save ...` from
scratch, those files will be missing again. A `godep save` to add new
dependencies without blowing away the `Godeps` directory should work
fine, though.

sync.Pool is after all faster than the home-made free list. Especially
under contention. To prove that, this commit also adds a benchmark for
concurrent fingerprint calculation.

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.

The Golang protocol buffer library has now moved to GitHub:

Although "go get"-ing the old package name still works, moving
everything to the new one will make vendoring cleaner.
