Fix a miscount of output flow control window for HTTP/2

2018-01-23T15:14:18+00:00

The miscount occurred because of a faulty iolist split function.
The bug should now be corrected, a PropEr test has been added
and a regression test has also been added.

Allow colon within path segments

2018-01-16T10:24:49+00:00

Allow `cowboy_router:compile` to handle colon characters within
path segments, rather than exiting with `badarg`.  This is allowed
via RFC 7230 2.7 -> [RFC 3986 3.3](https://tools.ietf.org/html/rfc3986#section-3.3):

```
      segment       = *pchar
      segment-nz    = 1*pchar
      segment-nz-nc = 1*( unreserved / pct-encoded / sub-delims / "@" )
                    ; non-zero-length segment without any colon ":"

      pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"
```

Add RFC 8297 to the list
