When a screen is removed, we have to update screen.primary (if it was the
removed screen) and assign a different screen to all clients which were on the
removed screen.

A client cannot be used any more after it was unmanaged. Similarly, Lua
shouldn't be allowed to e.g. assign a client to a screen that was removed. This
commit adds such a checker which "breaks" all screens which are not in the
global screen list.

This commit adds a "removed" signal to screens. Together with the "added" signal
that we have since a while, this allows the C code to update the list of
available screens dynamically without needing to restart.
So far, this code received only minimal testing. So far, I don't have a nice
idea on how to easily test this...

We once had the problem that with the nvidia blob, the X11 server told us that
"yes, I do support RandR; there is just a single big screen" even though there
were multiple screens and they could be queried for via Xinerama. To work around
this, we started to ignore RandR if it only provided information about a single
screen.
Our long-term goal is to stop restarting on RandR screen changes. Thus, even if
only a single screen is defined during startup, we should still use RandR later
when another screen is added. This means that we cannot just ignore RandR if it
only mentions a single screen.
This commit copies what GTK+ does: If there is an output named "default", then
some compatibility layer is assumed and we ignore RandR.
I have no way to test if this really does the right thing.

Instead of adding all screens directly to globalconf.screens, the individual
"scanner functions" now get a screen_array_t as their argument and add the
screens there. Also, they no longer emit the "added" signal themselves (through
screen_add()), but the caller does now does this instead once all screens are
found.
This commit drops the "deduplication" of screens. This likely means that clone
mode causes duplicate screens. This will have to be re-added later.

This theme draws a minimal wallpaper directly. This commit replaces the
ImageSurface of the wallpaper with a RecordingSurface. This shouldn't have any
visible effect, except for reducing memory usage, because an ImageSurface needs
a lot of memory and is only eventually released by the garbage collector. A
RecordingSurface instead just records the operations that were done which needs
a lot less memory for the simple operations done here.

This makes the code create a wallpaper of the correct size, instead of cairo
later having to scale the wallpaper up to fill the screen (if it has a different
size than screen 1).

to reproduce:
1) spawn an xterm
2) enter 'sleep 10 && killall xterm'
3) start moving the terminal
There will be an error
(found by a yet to be commited integration test)
* awful.widget.graph: add clear() function.
* awful.widget.graph: doc fixes for add_value.
add_value did not show up in generated luadoc. And the value parameter does not need to be between 0 and 1.
* awful.widget.graph: local functions clear and add_value as methods of graph.
There used to be `awful.client.data.focus`, which was moved to
`awful.client.focus.history.internal`.
While the former was accessible, the latter is not.
This is useful to get a list of most recently focused clients, without
having to hook into the signal yourself.

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.

When a tag is deleted, this code tries to select some other tag. If the tag
which is to delete is the last tag of a screen, this code failed and indexed a
nil value. Fix this with a simple "if".

If a screen is removed while a re-layout is pending, previously this code would
cause errors and problems. Since the screen is gone, there is nothing to arrange
anyway and we can just not do anything.

This commit changes some tables that are used for per-screen stuff to have weak
keys, so that the screens can be garbage-collected, if needed.

The min/max arguments to the integer range checking functions are integer. We
call these with UINT32_MAX in two places and this value (notice the "U" for
"unsigned") does not fit into a signed integer. Hence, there is an integer
overflow at compile time and the maximum value that is actually checked for is
-1.
Fix this by using lua_Number (double) instead of int.

When there is a maximized and floating client,
`awful.placement.no_overlap` would end up with an empty list of areas to
place the client into.
This patch fixes it to use the default `screen.workarea` in that case.
Closes https://github.com/awesomeWM/awesome/issues/813.
Rules refactor, part 1
This fix the following awful.rules bugs:
* **x**: Broken when "border_width" is set or left titlebars are used
* **y**: Borken when"border_width" is set or top titlebars are used
* **width**: See above + right litlebar
* **height**: Same as above
* **switchtotag**: Have a race with the "manage" -> "tag.withcurrent" code in `awful.tag`
* **tag**: Had dead code
* **screen**: Had a race condition with switchtotag
* **urgent**: Had a race with screen and another with switchtotag+focus
* **focusable**: Was broken yet again when request::activate was introduced (and also because of FS1098, that I also fixed)
* **no_overlap**: The "no_overlap" call in rc.lua "manage" section conflict with the geometry rules as the hints are not set (idk why).
* **size_hints_honor**: If set to false, it would be applied too late, causing height and width offsets due to placement or various geometry related properties
Remove request::fullscreen and request::maximized_* and use
a single request for them. The other client resizing features
will soon also start to use this.
Due to recent changes, it was no longer possible to disable the
default tag selection handler. This commit extend the already
existing request::tag mechanism to let handlers select the tags.
