The argument to luaL_checkstack() is the amount of new stack to make available,
not the new size of the stack. Thus, remove the addition of lua_gettop(L) here.

E.g. trying to press mouse button 1.5 via root.fake_input() doesn't make sense.
Previously the code silently truncated the number to an integer. Now it
complains about this instead.

The only remaining calls are for a window's opacity and in the DBus type

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).

Most of this information isn't interesting. If you are getting awesome from a
distro, then the time, hostname and username of the build are likely 'random
stuff' and if you are building awesome yourself, then the hostname and username
are obviously yours and the time can still be interfered based on the awesome's
binary ctime.
The GCC version shouldn't make any difference at all.

This makes it possible to add something similar to a __index / __newindex
metamethod to all our C objects. Based on this, Lua can then easily implement
arbitrary properties on our capi objects.
This saves the order of clients in a property called AWESOME_CLIENT_ORDER on the
root window during shutdown. During startup, after managing all existing
windows, we force the client list into the order described by this property
(overwriting any changes that Lua possibly did).
This code should safely handle cases where the property doesn't contain all
existing clients or contains a client which doesn't exist anymore.

Forgot to commit the change that adds _NET_FRAME_EXTENTS to the list of atoms
that we actually query for and export to the C code.

Run the following code:
do
local d
local f = function() d.visible = true end
if _VERSION >= "Lua 5.2" then
setmetatable({}, { __gc = f })
else
getmetatable(newproxy(true)).__gc = f
end
d = drawin({})
end
collectgarbage("collect")
Awesome will segfault.
The reason for this is that after the above code ran, all variables in it are
unreferenced and will be garbage-collected at the next sweep phase. Lua runs
garbage collectors in the inverse order that their corresponding objects were
"marked" which means for the above code that the drawin's garbage collector will
run before function f runs. So the code will access the drawin after its
destructor already ran. Obviously, awesome's C code does not expect nor
correctly deal with this situation and was dereferencing a NULL pointer.
To fix this, this commit "unsets" the metatable of a userdata object when it is
being garbage collected. Since the type of a userdata is inferred via its
metatable, the object will no longer be accepted by luaA_toudata().
For the above code this will result in an unhelpful error message saying that
something tried to index a userdata, but userdata cannot be indexed. At least we
no longer crash and the traceback of the error will hopefully point at some __gc
metamethod which should be enough of a hint to figure out the problem.

This property is especially useful for client objects which are unusable after
unmanage. "Unusuable" here means that pretty much everything you do with the
client object results in a lua error.
Syntax is c.valid.

Our tag concept doesn't really fit into ewmh. Thus, we were setting this
property to a way too small value anyway (just the size of the first screen in
case of multiple screens).
Since this property is optional in ewmh, let's just drop it.

If $SHELL is set to "bash", previously awesome failed to restart itself, because
it could not find "bash". This commit makes awesome use execlp() instead of
execl() which means that $PATH is searched if the started command does not
contain a slash and this problem is fixed.
$SHELL is specified in POSIX and it doesn't seem to require an absolute path
name.

Thanks to Michael Stapelberg, there is now a xcb-only port of libXcursor which
does everything we need. This patch switches awesome over to that new library.
Since the only reason for using XOpenDisplay() instead of xcb_connect() was so
that we can use libXcursor, we can get back to that older state again. This
means that this effectively reverts the following commits:
531f8b415c "Added initial support for Xlib cursor themes"
77243cd09a "Add x11-xcb to the pkg-config checks"
779d43fc46 "Don't let Xlib own the event queue"

I assume nobody have tried to compile Awesome with GNU uncompatible
compiler for ages and thus non-__GNUC__ p_delete version got
overlooked for quite some time.
First of all, a problem I see is that it assigns void** to a variable
of type void* and then dereferences the same void* variable.
None of the compilers I am aware of will let you go through this
without an error.
And second of all, lets have one portable p_delete.

This function can be called from unprotected contexts. Calling luaL_error() in
this case results in a call to luaA_panic() and awesome dies.
The only real change here is that this now calls warn() instead of luaL_error().
The rest is reindentation because warn() returns while luaL_error() didn't.
