Remove request::fullscreen and request::maximized_* and use

will soon also start to use this.
In the case where one want to put the cursor at the middle of the
workarea, it is logic to do:
x=screen.workarea.x+screen.workasrea.width/2
However, this can cause floating points. This commit move the
burden back to the C-API so the Lua placement code doesn't have
to add a large number of rounding methods. Given 1 type of rounding
cover a vast majority of use cases for each types of coordinates,
the C-API can take care of it in peace. For the other corner cases,
it is still possible for the Lua code to do the rounding there, but
no longer necessary. The convenstions are:
'x' and 'y': use round (move to the closest point)
'width' and 'height': use ceil (to avoid involontary truncating)
This change catches things like c:geometry { width = -42 }.

When minimizing a client, we temporarily ignore events for the client window (so
that we don't get the UnmapNotify event that we are causing for the unmap) and
for the root window (I don't actually know why, no "harmful" events should be
caused...).
However, we weren't ignoring events on the frame window itself. This commit
fixes that oversight.
The problem here is that the pointer could be inside the window that is being
minimized. When we then unmap said window, the pointer will now be inside of the
frame window and the X11 server will thus generate an EnterNotify. When we
handle this event later on, we emit mouse::enter on the client and e.g. the
default config then focuses this client, which undoes the minimization.
This fixes a regression introduced in commit 3aeac3870c and fixes#92.

Everything that needs the lua_State should create a local variable like this:

Previously we would get a short black flicker when a client closes. This

time, the X server filled the frame window with its background-pixel which was

This caused problems where clients would always spawn on the top-left screen and
couldn't be moved around. This was because lua placed them on the other screen,

This kind of forces every client to have a window gravity of "static".

only after the ungrab.
This means that we have already selected our event mask on the root window in

To fix this, we grab the server again and remove our event mask on the root
