daemon: Also store name, color, and avatar in dashboard configuration

shell: Update shell.hosts to new dashboard configuration storage

This takes color and avatar directly from the dashboard configuration,
and uses the name in the dashboard configuration as a cache for the
pretty name of the target host.

Also allow setting of the pretty name via shell.hosts.

We have a global rule which does this for .min.js files, but make
this one an exception.

base: Automatically register jQuery as an AMD module

If jQuery didn't get a chance to register itself as an AMD module
because it loaded before cockpit.js, we do so on its behalf.

There's a lot of default output on Fedora 21 by default, and this

bridge: Only do base64 decoding in one place in CockpitChannel

There's no need to do this in two places.
bridge: Add a prepare vfunc to CockpitChannel

The queueing of cockpit_channel_ready() and cockpit_channel_close()
was too magical and causing too much complexity.
bridge: When we receive clean close before ready, don't close yet

When we received data or a clean close before the channel is ready
don't close prematurely. Make sure all the data is drained, and
then do the clean close.
bridge: CockpitChannel "disconnected" when transport closes

The CockpitChannel closes unsuccessfully when the transport
closes. This lets implementations react immediately, even if the
transport closes without error.

bridge: More robust parsing of channel options

The parsing of channel options was quite haphazard, and didn't
detect bad types for values, etc. This is more verbose, but it's more
failure proof and produces better diagnostic messages.
bridge: Better diagnostics for file read/write failures

In the file read/replace channels, put some context in the messages
so we can have a clue as to what's causing it. Previously we had:

cockpit-bridge-Message: /tmp/.V3DRPX/foo: Bad file descriptor
bridge: Rename old rest-json1 code out of the way
common: Allow skipping bytes after in cockpit_pipe_consume()
bridge: Consistent parsing of address channel options

So we have consistent handling for both stream and the upcoming
http-stream1 channels.
