To ensure that some features such as SNID rules work, we need
to ensure that the screen isn't set by other code paths. Only
a single algorithm can be executed for the screen. As soon
as many algorithms are executed on events such as "manage", it
will most likely regress again.
This commit make sure of that by disabling the default normal source
of c.screen. After that, any other c.screen changes can be
considered bugs.
The requirement to call add_signal() was added to catch typos. However, this
requirement became increasingly annoying with property::<name> signals and e.g.
gears.object allowing arbitrary properties to be changed.
All of this ended up in a single commit because tests/examples fails if I first
let add_signal() emit a deprecation warning.

Tags are accessible as s.tags on a screen object. Yup, that's harder to find
than a variable that is defined in the default config, but such is life.
Now that awful.rules supports specifying tags by name, I guess that the number
one reason for needing the tags table is gone.
