For "stuff around screen's 'removed' signal", it might make sense to
temporarily set a tags screen to nil. The idea is that it will only
later be assigned to a new screen, not immediately.
However, currently a tag with screen nil causes quite some problems in
the set_screen() function. This commit works around this with a generous
amount of "wrap this in if".

When awful.tag.new() got a list of layouts shorter than the list of
names, it would previously create tags with nil as their layout. This
commit changes this so that the first layout is repeated if necessary.

Swap the parameters the next time the API break / deprecation season is open.
This is indeed confusing, as reported on IRC. The screen is *not* optional,
`awful.tag.find_by_name(name)` wont work
* Move table functions out of awful.util into new gears.table
* 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
The only other swap function is awful.tag.swap and that one is
deprecated. Thus, it should not be linked to.

The usual "a or b"-trick to simulate C's ?:-operator does not work when
"false" is a valid value. Fix the code to handle this correctly and add
a short unit test which would have caught this problem.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

Instead of using magic with a weak table, the code now saves this data
as a property under the tag object. This avoids all kinds of leaks, for
example caused by t.foo = t.

This adds a tparam alias "@screen" for "@tparam screen" (when used to
document e.g. arguments for callbacks), and "@screen_or_idx" when a
function accepts a "screen" or "number".
This commit remove the `awful.tag` "manage" hook. The relevant
code has been moved to ewmh.lua request::tag handler. The handler
is called either by a volontary screen change or by a forced one.
It also require the awful.rules to be executed. This is done by
default and the user would have to explicitly disable that
behavior. From now on, disabling the rules require the user to
handle tag selection.
Fixes#1028#1052
There was still a problem that caused the "old" tags to be
inserted in the wrong position when "saved" from a screen being
removed.
Also, this use a :get_tags(true) to save an uneeded sorting pass.
The index was updated on an unordered table. As the elements
order did not match the relative indices once they have been
changed, further calls to set_index produced garbage.
The default taglist didn't notice because it use screen.tags
table index instead of the tag index. A debug using
echo 'for _,t in ipairs(mouse.screen.tags) do
print("INDEX:", _, t.index, t.name) end' | awesome-client
Would have shown two or more elements with the same index. To
debug issues related to tag indices, this bash script can be
enabled:
while true; do
echo 'for _,t in ipairs(mouse.screen.tags) do
assert( _==t.index) end' | awesome-client
sleep 0.5
done
If:
1) An app is open in a tag
2) A new tag is created
3) The app is closed in the first tag
4) The first tag is deleted
5) The new tag is deleted
Then this history would try to restore an inactive tag without
a screen. Bad things will then happen.
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.

Since the screen removal patchset, the tags properties were
cleaned too early. This caused code connecting to "property::activated"
to be called with the tag already partially deleted. For code depending
on those properties, such as radical.impl.taglist, this caused errors.
Any clients with these tags end up somewhere random (the first tag on the first
remaining screen). This certainly can be improved in the future, but at least
this is a start.

When this force-argument is not given, the code will refuse to delete a tag
which has a non-sticky client. With this force argument, the client will just be
moved to the fallback tag.

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".

There was a regression when refactoring the API. It was no longer
possible to disable the automatic tag selection.
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.
