shell: Always do a coldplug for any change on #storage

This is more robust.  For example, get_block_devices_for_drive might
not return all block devices yet when a drive object is added, which
becomes important when we want to monitor I/O for drives.

In order to avoid excessive churning during initialization, multiple
change events in the same event loop iteration are collapsed.

We don't include mdraid or lvm in the graphs since we show their I/O

session: Clear environment when running cockpit-session setuid

Environment variables can affect all sorts of things like LD_PRELOAD,
PAM module behavior, and so on. When cockpit-session is running as
a setuid process, clear the environment completely.

This means that for debugging using G_DEBUG or G_MESSAGES_DEBUG
cockpit-ws must be running as root. Update HACKING.md to reflect this.

ws: Only one code path for starting local cockpit-session process

Don't automatically launch local cockpit-session processes when
opening channels. The only way to get one is via a /login.

This simplifies the authentication code, but more importantly
once GSSAPI is implemented, we won't necessarily have the credentials
to just launch a cockpit-session whenever we want.

ws: Log the user out when the primary session goes away

If the primary session goes away (eg: via a kill command or crash)
then log the user out of the web service all together.

ws: Move cockpit-session code to src/ws/ directory

It's really part of the webservice code rather than the agent, and the
API that cockpit-ws and cockpit-session talk is pretty tightly bound.

common: When JSON data to parse is empty, raise an error

Explicitly raise an error when JSON data to parse is empty.
This was causing issues when empty data would come from cockpit-session.

ws: In preparation for GSSAPI move authentication to headers

Use the standard Authorization header and Basic auth for authenticating
via passwords.

We parse the authorization header in cockpit-session, similarly to how
we'll be doing for the GSSAPI (ie: kerberos auth)

ws: Pass headers to CockpitAuth login_finish() virtual method

In our GSSAPI authentication we'll be adding custom headers from
