For example, Xephyr reports its output with a size of 0x0. Since a
division by zero is in no one's interest, just ignore such outputs when
trying to compute the DPI value.

Running test-menubar.lua just failed for me locally. The reason was that
the textbox was indexing a nil value when doing 's.dpi'.
This commit fixes the menubar so that its optional screen arguments are
really handled correctly. In fact, a default screen is now chosen way
earlier than before, so that no nil values are used as screens later on.
In other news: I guess test-menubar.lua is not run on any of our Travis
targets...

This commit makes awesome automatically compute the DPI of a screen
based on its RandR outputs. If multiple outputs exist, the lowest DPI is
used.

Once upon a time, beautiful.xresources.get_dpi was added to query
Xft.dpi. That made sense since this queried an xresources property. Over
time, other, non-xresources-based ways to query DPI were added to this
function. Now, it makes no more sense to have this function here.
Also, recently it became possible to add new properties to C objects
from Lua code. Thus, we no longer need to have a get_dpi() function
somewhere, but can add s.dpi directly.
Thus, this commit adds s.dpi and makes everything use it. No functional
changes are intended.

To apply the shape of a client, we have to create an image and draw the
shape we want to it. Since clients can be quite large, we have to make
sure that we do not keep this image alive unnecessarily long.
The code in awful.client.shape.get_transformed() however needs another
temporary surface in case the client has its own shape and another one
was set in Lua (side note: currently the code also creates this extra
temporary surface if the client does not have its own shape; that might
be worth fixing). This temporary surface is then used as the source of a
cairo context to draw it to the image that will be used as the client's
final source.
After we are done, the temporary surface is still kept alive since it is
the current source of the cairo context. The cairo context in turn is
only freed when Lua's garbage collector collects it, which may take
quite a while.
Improve this by setting a different source to the cairo context. Thus,
it now releases the temporary surface as soon as possible and it is only
allocated for a short time.

This fixes a regression introduced in be29ee6768. This commit changed
naughty to reuse an already-existing wibox when replaces_id is used,
instead of creating a new wibox. However, some of the properties that
are set only when creating a wibox were ignored due to this.

The magnifier layout handles the currently focused client specially.
However, if the currently floating client is floating, it should not be
handled by the layout at all. A bug caused the magnifier layout to
handle a focused and floating client anyway if it was the only tiled
client.
Fix this by removing the '#cls > 0'-case. If #cls == 0, then no client
is available to be managed. Thus, cls[1] will be nil, which is fine
since, well, no client is available to be managed. This only made a
difference in the specific bug that I described above. Thus, drop this
case.

Several themes use `dpi(2)` which is quite thick, and it is better to
use the default of 0 here, instead of `beautiful.border_width`, which is
meant for borders on clients.
This function draws the wanted shape to a cairo image surface and then
uses it to set the shape of the passed-in object. After this commit,
this temporary image is finished afterwards, making it free most of its
memory immediately instead of only later when the garbage collector
collects the image surface.

When doing w.shape_bounding = foo on a wibox, the code would first read
shape_bounding from the underlying drawin. This would create a
(possibly) huge cairo image surface that just waits to be collected by
the garbage collector, resulting in increased memory usage.
Fix this by checking the force_forward table first. This tables contains
the names of shape properties. Thus, the evaluation of this statement
gets short-circuited and the property is on the drawin is not read.

I am not sure what exactly goes on in the below bug report, so this will
just paper over the problem. I still think that this patch is a good
idea even when it is not a proper fix, since keyboard layouts are
complicated and so this code should be robust and hard to break.

When gap_single_client is set to 'false', no gap is used when only one
client is shown in a tag. Since the max layout only ever shows one
client at a time it makes sense to apply this setting for this layout
regardless of the actual number of clients in that tag.
Additionally, if the 'master_fill_policy' property is set to
'master_width_factor', then use a gap even if there is only one client
visible and 'gap_single_client' is false.
There were multiple things which stood out to me, as I was trying to setup a simple calendar popup for my textclock:
1.: The functions in https://awesomewm.org/doc/api/classes/awful.widget.calendar_popup.html#Functions were not named correctly (calendar vs calendar_popup) which (naturally) produced an error when used as awful.widget.calendar.month() .
2.: The example for calendar_popup.month() was obviously missing a line (where does the month_calendar come from?) . Resolved by copying the line from the attach-example
3.: The same examples also only refer to the function as calendar.month() which should be changed to awful.widget.calendar_popup.month()
This now runs parse_desktop_file in a protected context so that a single
broken desktop file does not break the whole menubar.
Also, the error message that is produced when a Lua error occurs now
also includes the file name of the .desktop file which we attempted to
parse. This should help quite a lot in debugging.

1. before this patch the "Shift" key(s) to get to Shift-Tab would reset
ncomp already.
2. "Shift-Tab" will come in as "Tab" with mod.Shift typically.
3. cur_pos and ncomp have to get reset in case of going back to the
original entry.
This allows, for example, to imeplement the tag `master_fill_policy`
and simplify the client layouts by not having to hardcode empty
columns and rows in each layouts.
Without this, users would modify the beautiful table directly instead of
the theme. This made a difference for code using beautiful.get() to get
the theme.

If an error occurs while a layout is being applied, arrange_lock could
get stuck at true, meaning that no more re-arranges will happen, thus
breaking the whole layout machinery.
Such errors could happen because the layout itself produces an error,
but also because a width is too large and c:geometry() throws an error.
Thus, this commit moves all of the actual "apply a layout"-code into a
protected context.

Using `beautiful.get()` has the drawback of not supporting theme
variables set from `rc.lua`. It is also used less often than
direct theme access, making it a bit inconsistent with how other
modules behave.
The return value for this function is used as an index in a table and
Lua does not like nil as an index.
The function that actually looks for icons, find_icon_theme() already
falls back to "hicolor" if it does not find anything via the current
theme, so fix this issue by just falling back to "hicolor" here as well.

Previously, the lgi check used the normal Lua interpreter to check if
lgi is installed. However, nothing ensures/requires that awesome is
built against the same Lua version as the Lua interpreter. This means
that if lgi is only available for some Lua version, then the check could
succeed even though awesome would later fail to start. Also, the check
might have failed even though awesome would not have any problems
finding lgi.
This commit replaces lgi-check.sh by a small C program which does the
same thing. This ensures that the same Lua version is used as awesome
will be using.
There are some places that still use the Lua interpreter: Example tests
(run through the Lua interpreter directly) and unit tests (run through
busted). For unit tests, this should not make much of a difference and
example tests might later get similar treatment.
