Gary Burd a87eae1d6f Add hooks to support RFC 7692 (per-message compression extension) 
Add newCompressionWriter and newDecompressionReader fields to Conn. When
not nil, these functions are used to create a compression/decompression
wrapper around an underlying message writer/reader.

Add code to set and check for RSV1 frame header bit.

Add functions compressNoContextTakeover and decompressNoContextTakeover
for creating no context takeover wrappers around an underlying message
writer/reader.

Work remaining:

- Add fields to Dialer and Upgrader for specifying compression options.
- Add compression negotiation to Dialer and Upgrader.
- Add function to enable/disable write compression:

    // EnableWriteCompression enables and disables write compression of
    // subsequent text and binary messages. This function is a noop if
    // compression was not negotiated with the peer.
    func (c *Conn) EnableWriteCompression(enable bool) {
            c.enableWriteCompression = enable
    }

Gary Burd 703e8da19b Drop Go 1.3 from supported configurations 
The code does not build on 1.3 because tls.Config does not contain the
GetCertificate field. This can be worked around using build constraints,
but it does not seem worth the trouble.

Gary Burd 5a00fb2e99 Do not shallow copy crypto/tls.Config 
The Config contains a sync.Once that should not be copied.

Gary Burd 3986be78bf Split raw query from opaque in URL parser 
Prior to this change, the client passed query strings from the
application to the network via the net/url#URL.Opaque field. This works,
but may not be something the authors of the net/url and net/http
packages expect. To play it safe, this change parses the query string to
the net/url#URL.RawQuery field.
