beorn7 98eb6cbf7c promhttp: Correctly detect invalid metric and label names
Without this fix, the `InstrumentHandler...` middlewares get locked in
an endless loop in case of an invalid Collector, eating all the memory.

beorn7 14730c70c0 promhttp: Bite the bullet and implement all 32 possible interface combos
As it turned out, it's not that esay to guess "common" combination of
interface upgrades. So I decided to just implement all 32 possible
combination of interface upgrades. (Only 16 with Go 1.7 and earlier.)

Clearly, this calls for code generation. But right now, we still need
to find out what's the best form of the code. For later additions,
implementing code generation might be useful.

Note that newDelegator is called for each HTTP request. Thus, this
commit aims to make the upgrade selection quick. (After the type
checks, it's just directly accessing an element in a slice.)
