case it's valid.

bridge: Implement an echo channel payload

And a test that uses it. This will become useful for checking of
behavior of binary channels independent of the channel implementation.

bridge: Support for binary and base64 encoding in channels

This is mostly underlying work, and not yet exposed in cockpit.js
By passing "binary": "raw" in a channel raw data will be sent, this
is used by the resource1 channel for now.

By passing "binary": "base64" in a channel, all received data will
be assumed to be base64 encoded, and sent data will be encoded on
the way out.

bridge: Rename 'text-stream' payload to 'stream'

Depending on whether the channel is binary or not, the stream can handle

base: Use the shell to determine default host if loaded into shell

When cockpit.js code is loaded into the shell, use the shell to determine
the default host rather than requiring it to be passed in all over the
place.

This lets us write future proof code. Later on when everything is migrated
we can remove this hack.
