+ can: add `spray.can.client/server.incoming-auto-chunking-threshold-size`, fixes #189

The setting is still disabled per default because it is not yet clear
how the higher-level API are going to deal with it generally.
= can: add streaming file upload code to simple-http-server example

This is the most basic form working with the current version of the
chunking message protocol. Once we have implemented registering for
chunked messages the `chunkHandlers` map can go.
+ httpx: add support for specifying an optional log level with logRequest and logResponse

The default log level is still DEBUG but now you can specify your own level. this was already exposed by logValue but had not bubbled up to logRequest/logResponse.
= can: always produce chunks if Content-Length >= autoChunkingThreshold

I.e. also when the complete body is already available. Thanks, Bob Ngu for
the fix.

! util: Swap Duration.Undefined by Duration.Inf, fixes #440

When confugarion is read using the pimped getDuration method the
mapping for "infinite" was Duration.Undefined, but Duration.Undefined !=
Duration.Undefined, which makes comparing any internal settings representation
containing a Duration in a sure failure. Duration.Inf make a lot more sense.
