Uli Schlachter ec3901a81e Rewrite the xcursor caching code
Previously, the cache for xcursors consisted of a static array. We had a
hardcoded list of supported cursor names and each one got assigned a
position in this array. This hardcoded list means that one cannot simply
use whatever cursor a cursor theme happens to provide, since the name
needs to be in our list.

In this commit, the code is rewritten. Instead of a hardcoded list, a
sorted array is now used as the cache, as provided by the BARRAY code
from common/util.h. The array is sorted by the name of the cursor.

This change implies an API change for the xcursor code. Previously, one
had to first translate a cursor name into a cache index
(xcursor_font_fromstr()) and could then use this to actually get the
cursor (xcursor_new()). With this commit, xcursor_new() is the only
function provided by the cursor code and it directly gets a string as
argument.

Emmanuel Lepage Vallee d58b4c3d96 cmd: Add more info to --version.
Now that modeline are supported, they will affect the content of
version. This commits only adds the new information. `--version` has
to be the last command line argument and the modeline isn't parsed
yet.

Another commit will make sure --version parses the modeline and
finishes to process the command line arguments in case it isn't
last. Please note that luarocks also affects data points such as
the LGI version. It should be smarter and check if `rc.lua` has
`require("luarocks")`. This commit does *not* do it.

Emmanuel Lepage Vallee ee80fe052f init: Add an API level concept to `capi`.
The API level concept is something used by other projects such as
Android and iOS to allow deprecated features to be removed and the
bahavior to be altered without breaking compability with existing
code.

The same will apply to AwesomeWM. The current API level is "4" and
as long as config use this, no deprecation or bahavior change will
be exposed. If the user sets it to an higher value or we release
the next major version and new users start to use the, then current,
default config, they will use the new API level.

The the far future, if ever, we could fork the entire Lua libraries
to support legacy APIs. This would only require to keep the core
API support for those legacy calls. In the meantime, `gears.debug`
will use this to manage the deprecation and some conditional code
will be added as a last resort attempt to preserve behavior
compatibility while moving forward with breaking changes.

Emmanuel Lepage Vallee 433898599d init: Add a command line option to start AwesomeWM without screens.
This commit add an optional `--screen off` command to initialize Lua
without first adding the screens. This is inconvinient for most users
since it restrict the APIs that are usable out of the box.

However, this allows AwesomeWM to work independently from the hardware.
This means that when a screen is unplugged, it is the Lua code that will
remove the screen instead of CAPI pulling the carpet from under. It also
allows to ignore some screen areas before the screen is ever created.
Combined, it makes it possible to work with screens even when they are
physically disconnected. Finally, it will allow for an awful.rules like
API to control how screens are created.

All in all, some people need this for their setup and some people might
want to do it anyway for fine grained and/or dynamaic multi-screen
setups.

This commit also adds 4 new signals to `capi` to be able to
execute code at specific points during the initialization. The commit
improves naughty error notifications to work even if problems occurs
before the screens are added.

Note that AwesomeWM will exit if no screens are created. While it would
be easy to just call `refresh_screen();` after unsetting the magic
variable, doing so would have corner cases. Better be harsher and
prevent the user from shooting themselves in the foot from not reading
the f****** manual. Code introduced in future commits will take care
of automatically calling fake_screen in the event nothing is created.

Uli Schlachter a57c79687a Use xcb-errors library if it is available
This library allows to get a human-readable string describing X11
requests, events, and errors. We now use this library to pretty-print
X11 errors if we get any.

To test this code, I added the following two lines to AwesomeWM so that
X11 errors are generated:

    xcb_set_input_focus(globalconf.connection, 42, 42, 42);
    xcb_randr_set_output_primary(globalconf.connection,
        globalconf.screen->root, 42);

Output without xcb-errors:

    X error: request=SetInputFocus (major 42, minor 0), error=BadValue (2)
    X error: request=(null) (major 140, minor 30), error=(null) (147)

Output with xcb-errors:

    X error: request=SetInputFocus (major 42, minor 0), error=Value (2)
    X error: request=RandR-SetOutputPrimary (major 140, minor 30), error=RandR-BadOutput (147)

Uli Schlachter 9f3a6757e9 Asynchronously update the keyboard state
When the keyboard layout is modified via xmodmap, each single "change"
(line of input to xmodmap) causes an "the keyboard configuration
changed"-event to be sent. Awesome reacted to each of these events by
reloading the keyboard layout. Thus, awesome reloaded the keyboard
layout a lot and appeared to freeze.

Fix this by asynchronously update the keyboard state: When such an event
comes in, instead of reloading things immediately, we set a flag which
makes us update the state at the end of the main loop iteration. This
means that many events still cause only a single (or at least few)
re-quering of the layout. Thus, a lot of time is saved.

This commit removes the argument to the (undocumented!) signal
xkb::group_changed. Previously, the argument was the active group
number. Since this argument was unused and I'm lazy, I just removed it.
The alternative would be that it might be visible to Lua that some "the
active group changed"-events are dropped.

Uli Schlachter 3bd045b57c Check for pending events after the main loop (#1163)
At the beginning of every main loop iteration, we check for new events
from the X11 server. However, it's theoretically possible that during a
main loop iteration new events arrive and are read by libxcb into its
internal buffer. This would mean that the fd connected to the X11 server
is not readable and thus we do not wake up to handle these events.

Handle this by checking for pending events before calling poll(). If a
new events appears, we set the timeout for poll() to zero and will then
handle the new event in the following iteration of the main loop.

Uli Schlachter 06f02f6004 Delay client frame window destruction (#1148)
Daniel sees a short flicker of his wallpaper when he closes a client.
This happens because the window is destroyed immediately, but other
clients are re-arranged only shortly later. In the mean time, the X
server updates the display and repaints the root window (= wallpaper
becomes visible).

Work around this by delaying the destruction of frame windows to the end
of the current main loop iteration. This means that we first update the
position of all other windows and later destroy the window that was
actually closed.

Uli Schlachter 19094de661 Speed up client_ignore_enterleave_events()
There are some situations where we do things that can make the mouse pointer
enter another window. We do not want to react to these "self inflicted" mouse
enter and leave events, because they aren't "real" (= generated by the user).

Before this commit, this is done by going through all windows and toggling the
"please send us enter and leave events"-bit on them. This becomes slower when
many windows are visible and floods the server with requests.

This commit changes this to a constant-time logic. Each event contains the
sequence number of the last request that the X11 server handled. Thus, we just
remember the right sequence numbers and ignore any events that comes in whose
sequence number falls into the ignored range.

In detail, we keep a list of "begin" and "end" sequence numbers and ignore any
enter and leave events that fall in this range. If we get any event with a
sequence number higher than "end", we remove this pair from the list, since it
is no longer needed.

To generate these pairs, we use a GrabServer request in
client_ignore_enterleave_events(). This gives us a sequence number and makes
sure that nothing else besides us can cause events. The server is ours! In
client_restore_enterleave_events(), we first do a NoOperation request to
generate the sequence number for the end of the pair and then do UngrabServer.
Any event that is generated after UngrabServer will have at least the sequence
number of the UngrabServer request and thus no longer fails between begin and
end.

Uli Schlachter 80a6f2f510 Clean up static variables in event_handle
This function needs the event numbers for events from some extensions. These are
assigned dynamically by the server. Right now, this is done by having a bunch of
static variables that are initialized when needed.

Refactor this to have a function event_init() instead that sets variable in
globalconf (where all of our state should be saved). Also, a preprocessor macro
is introduced to handle event dispatch which also looks a bit nicer.

Uli Schlachter 2f78ec5b30 Never explicitly focus the root window
Whenever client.focus == nil, we set the input focus to the root window to
express "nothing has the input focus". However, thanks to the way X11 input
works, this means that whatever is under the mouse cursor gets keyboard input
events. This can easily be reproduced with urxvt and some small addition to the
config to unfocus things.

This commit changes things. Instead of focusing the root window, we create a
special "no focus" window that gets focused if we want nothing to have the
focus.

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