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 / ":" / "@"
```

2017-12-12T10:37:48+00:00

Add more rfc7231 tests and a new max_skip_body_length option

2017-12-07T21:33:52+00:00

The option controls how much body we accept to skip for HTTP/1.1
connections when the user code did not consume the body fully.
It defaults to 1MB.
