Rework the signature aka fingerprint functions.
...
Move everything over to a more expensive but less collision-prone way.
However, keep the old fingerprinting under the name "FastFingerprint"
to be used in the storage layer (where we need collision detection
anyway).

it.

Always build the procfs collector.
...
The cgo dependency in the "procfs" package is being removed in:
https://github.com/prometheus/procfs/pull/4
So now it should be fine to always import the "procfs" package and have
it determine dynamically at runtime whether the proc filesystem is
actually there.
This fixes a problem for users which were vendoring client_golang on
MacOS X, but building the result on Linux (the procfs package was
missing in the vendored packages).

Allow the metric family injection hook to merge with existing metric families.
...
If a metric family returned by the injection hook already exists (with
the same name), then its metrics are simply merged into that metric
family. With enabled collect-time checks, even uniqueness is checked,
but in general, things stay the same that the caller is responsible to
ensure metric consistency.

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.
