GLib has an internal pseudo-RNG that it initialises from /dev/urandom.
This commit adds code that uses this RNG to initialise various random
number generators that can be used by Lua.
This also removes some Lua code that initialises the random number
generator badly.

In Lua 5.1, xpcall() has exactly two arguments: The function to call and
the error handler. Everywhere else, xpcall() passes extra arguments on
to the function to call. This includes LuaJIT, however since LuaJIT sets
_VERSION to "Lua 5.1", so far gears.protected_call used the workaround
for Lua 5.1 here.
This commit switches gears.protected_call to actually test for this
feature instead of just guessing based on _VERSION. Thus, this now also
uses the better code with LuaJIT.

When calling join with e.g. arguments (nil, {"a"}), then everything past
the nil was ignored, because the code internally used ipairs() to
iterate over the arguments and this stops at the first nil it
encounters.
Fix this by using select() to iterate over the arguments.
This also adds a unit test for this problem.

`pairs` order isn't defined and `{...}` will always be ordered.
There is no reason to have random behavior where it can be
predicted at no additional cost.
This now does directly what previously awesome.load_image() did. Also,
this commit removes the only caller of awesome.load_image(), so that
function could (in theory) be removed now.

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.

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.

Regression in v4.1. It causes the `rc.lua` (and the fallback) to
exit when the wallpaper is missing or something went wrong.
In <= 4.0, the wallpaper wasn't loaded, but Awesome didn't "crash".
There should be no asserts in the code called during the first
event loop iteration.
The longer name is a bit more self-explanatory. The plural is meant to
indicate that this recursively creates missing parent directories and
does not just try to create the single given target directory.
Since filesystem.mkdir() is part of the v4.1 release, a deprecation stub
is needed.

* travis: Use v9999 prefix for full requests
Make sure no newly deprecated functions are used
* Move all `awful.util.table.*` calls to `gears.table.*` calls
Move table test functions from awful/util_spec to new gears/table_spec
Change awful.util.subsets call to gears.math.subsets in awful/key.lua
This extracts the code for finding the next screen
from focus_bydirection to a separate method on
the screen object.
The main reason was to use the finding code without
actually changing the screen focus but this should
incidentally make the code slightly easier to test
as well since both concerns can be tested in
isolation.

If the caller provides a file name, these function load the image, set
it as the wallpaper and make sure that the memory used for the image
data is freed immediately. However, this was also done when the caller
provided a cairo surface, thus breaking their surface.
Fix the code so that it does not finish surfaces that it did not create
itself.

Also save some boilerplate code.
This closes the gap between timer.start_new and timer.new. Now the
only difference is that one have a special callback format while
the other only has predefined properties.
We already have a variant of this function for transforming an actual
matrix. This adds the corresponding static factory.

For some reason, the code here tried to handle widget::redraw_needed
signals even though it should apparently/obviously only produce a

While here, also factor out the widget context table into a local

Previously, gears.object.properties used a weak table for adding
additional information to a C object. However, weak tables can easily
cause leaks when the value references the key.
This commit makes the code instead use the new .data property that is
available on all C objects. This means we have no more magic with a weak
table and instead only use "regular" tables instead.

All other shape did it. While it usually have no side effects,
as seen in #920 screenshot from @actionless, there is instances
where this produce a invalid rectangle.
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.

Similar systems already exist un luaobject, wibox and the declarative
widget system. This close the gap and also bring the property based
syntax to wibox and other gears.object users.
While this need to be enabled explicitly for legacy reasons, it
doesn't break the API.
Once widespread, this implementation will replace the one found
in wibox.widget.base_widget.
The code in gears.wallpaper currently sets a wallpaper in a deferred fashion.
Only a while after it is told to do something does it actually do the wallpaper
change. This is to incorporate many wallpaper changes right after another. These
changes happens during startup where the wallpaper for each screen is set one
after another.
However, since we no longer restart on RandR changes, the screen configuration
could change while we have a pending wallpaper. In this case, part of the
wallpaper could be "chopped off", because the surface that we draw the wallpaper
to is too small.
This commit makes gears.wallpaper track the size of the pending wallpaper and
create a new surface if the already-pending one is too small.

gears modules usually don't depend on Awesome C-API. This code has
been placed there for unclear reasons.
Also, there is ongoing work to unify each "concepts" API into one
single page. Having `gears.screen` go against this effort.
This adds gears.screen which contains a wrapper around
screen.connect_signal("added", func) that also calls the callback function for
each screen that already exists. This is added in gears.screen so that it can
also be used from e.g. wibox, if needed. Feel free to move this elsewhere if
that's a bad idea (I'm not really convinced of it).

Instead of using a special _call field on gears.matrix instances which has to be

Wallpapers are usually big images that use up a lot of memory. This commit makes
gears.wallpaper call :finish() on all involved surface to make them free their
memory.
This is a lot faster than waiting for the garbage collector to collect these
surfaces. Due to the large size of wallpapers, such a special case makes sense
for this code.

Loading a file normally has the same behaviour as before. First the cache is
checked and if nothing is found, the file is loaded and cached.
This commit changes the behaviour of loading a file uncached. This no longer
removes the file from the cache if it is cached (why should it?) and also does
not put it in the cache.
This means that users of load_uncached and load_uncached_silently can now freely
modify the resulting surface without interfering with other API users.
