Support bytestring-0.11

@Bodigrim The next is this library. Should I add base >= 4.9 to all metadata on Hackage?

[Bodigrim]

We need somehow avoid an unbuildable combination of base-4.8 and bytestring-0.11. I'd say that revising with bytestring < 0.11 is less controversial than with base >= 4.9, but whatever floats your boat. If you are reluctant to make a new release, you can, for instance, revise everything except logger-3.0.2 with bytestring < 0.11, but revise logger-3.0.2 with base >= 4.9.

I will do anything to help users if I'm convinced. :-) Does the follow work well?

• Releasing new fast-logger and wai-logger with base > 4.9.
• Modifying all old metadata with bytestring < 0.11.

[Bodigrim]

Yes, sounds good. You probably do not need to revise existing releases of wai-logger: once fast-logger has necessary bounds in place, wai-logger is protected from unbuildable configurations as well.

@Bodigrim Done for fast-logger. Please check. If OK, the next turn is http2.

All good, thanks!
