Uli Schlachter 5e6a893207 Replace various calls to warn() with luaA_warn()
luaA_warn() prints a Lua backtrace and thus generates more useful output. warn()
should only be used in awesome-internal places (e.g. receiving an error from the
X11 server).

Closes https://github.com/awesomeWM/awesome/pull/608.

Uli Schlachter a8ac146bd0 awesome.spawn: Add exit status support
This adds a new argument to awesome.spawn. This argument is a function that will
be called with the exit status once the spawned process terminates. For normal
exit, the function is called with "exit" and the exit code. If the process is
terminated by a signal, the function will be called with "signal" and the signal
number of the signal that caused termination.

Uli Schlachter 9afb2578f8 Spawn: Improve handling of startup notification
The ID for startup notification is transmitted to the spawned process via the
DESKTOP_STARTUP_ID environment variable. Before this commit, we set this
variable in the main process. This meant that if we started something "without"
a startup id, then it might get the ID that was used by the last spawn and which
was still saved in our env. Fix this by setting the environment variable only
after fork().

Small anecdote: The above wasn't enough to make Daniel's test case succeed and
at first I couldn't figure out why.

Turns out that rxvt-unicode doesn't unset the DESKTOP_STARTUP_ID environment
variable (I think it should, according to some spec), even though it supports
startup notification. So awesome was already started with DESKTOP_STARTUP_ID set
and thus all spawned processes used this ID.

Fix this by explicitly unsetting DESKTOP_STARTUP_ID if we don't set any new
value (even though this breaks encapsulation; we shouldn't have to care about
this "implementation detail" of libstartup-notification).

Uli Schlachter e5120e1bec Hide globalconf.L
Everything that needs the lua_State should create a local variable like this:

  lua_State *L = globalconf_get_lua_State();

This ensures that the compiler warns if there are two variables with name "L" in
scope. The idea here is that it should become harder to accidentally use the
global lua state instead of the state of the current state.

While writing this commit, I found another place that gets its wrong: Reading
client.focus from a coroutine was broken, since it was returning the result on
the main thread instead of the current one.

Emmanuel Lepage Vallee d6e06450d3 Add end to end support for spawning tracking using startup notifications
This allow to spawn something, then apply some properties or rules when
the client show up ("manage").

This commit add:
 * "startup_id" property for all clients object (immutable, can be nil)
 * Second return value to awful.util.spawn() with the startup_id
 * Update the documentation

Example:

  local wait_for_it = {}

  local pid,snid = awful.util.spawn("urxvtc")
  wait_for_it[snid] = {ontop=true,sticky=false,
     tag = awful.tag.gettags(mouse.screen)[1] }

  client.connect_signal("manage", function (c, startup)
     if c.startup_id and wait_for_it[c.startup_id] then
        for k,v in pairs(wait_for_it[c.startup_id]) do
           c[k] = v
        end
        if wait_for_it[c.startup_id].tag then
           c:tags({wait_for_it[c.startup_id].tag})
        end
     end
  end)

Uli Schlachter f9a1093e45 spawn: Remove useless argv[0] calculation
Since commit 3c40d6b, the passed in argument is decomposed into an array of
strings before the sn-related code runs. This means we already know argv[0] and
thus we don't need the code here that tries to figure it out again.

Uli Schlachter 5432e0a332 awesome.spawn(): Check table arguments better
Previously, any not-string-convertible entry in the array argument would result
in lua_tostring() returning NULL which g_strdup() would pass through. Thus, we
would end up with a NULL entry in an array whose end is marked with a NULL
entry. This mainly means that we had a memory leak.

Fix this by actually verifying that we only have strings in the table that we
are looking at.

Uli Schlachter 800a9a41f6 spawn: Don't try to spawn with empty argv (FS#1225)
When e.g. calling awesome.spawn({}), our argv array would be empty, so just a
pointer to a NULL pointer that marks the end of the array.

Since startup notification was enabled, this would then try to figure out the
name of the started binary. This would immediately dereference a NULL pointer
and crash.

  awesome.spawn({ "bash", "-c", "echo \"foo\"" })

Uli Schlachter ea30119410 Use glib instead of libev
This commit ports awesome from libev to the glib main loop. This means that
awesome has fewer dependencies, because we were already depending on glib before
and now no longer need glib.

However, the main reason for this change is that, thanks to lgi, we have glib
bindings for lua. This means that lua code can add all kinds of event sources to
the main loop (timeouts, fd watchers, SIGCHLD watchers, ....). Yay

This adds a callback function which glib calls after it fork()'d and did all the
necessary setup. This callback function clears our signal mask.

This is necessary because libev 3.8 and later use signalfd and therefor have to
add those signals to the signal mask. Processes started through awesome would
inherit this signal mask and I can tell you, some app which ignores ctrl-c
confuses people a lot.
