Uli Schlachter 782adcfd29 signal.h: Introduce signal_array_getbyname()
This is a nice utility function that actually does what most callers
want, instead of signal_array_getbyid() which requires callers to come
up with the signal id.

Uli Schlachter 75ed165ae6 Test & fix a bug with dbus.disconnect_signal (#1096)
The code was written so that it assumes that disconnecting the last signal also
removed the corresponding entry in the signal array. This lead e.g. to an
index-out-of-bounds access in some cases.

Uli Schlachter 6f1df7a3ad Fix disconnecting not connected signals (#950)
When a function is disconnected from a signal ("disconnect_signal") that is not
actually connected to the function, two things happened:

1. The attempt to remove the function from the signal array didn't do anything
2. Unreferencing the function noticed that the function wasn't referenced

The second step printed a big, fat scary warning.

Actually, this has the possibility of causing errors. For example, in the
following code, awesome would wrongly unreference the function at the
disconnect_signal() call and might later still try to call it when the
"refresh" signal is emitted:

do
    local function f() end
    awesome.connect_signal("refresh", f)
    awesome.disconnect_signal("debug::error", f)
end

Fix this by making signal_disconnect() return a boolean value indicating if it
actually did something. All callers are fixed to use this value and only update
the reference counts if something was actually disconnected.

Uli Schlachter d2b1e92f9e Clean up header includes
Every .c file has to include the corresponding .h file first to make sure the
headers are self-contained. Additionally, this moves some unneeded includes
around.

Gregor Best c2ea920ca0 remove encoding=utf-8 from modelines
This option is no longer valid in modelines, so it has been removed from
all modelines using the following shellscript:

    #!/bin/ksh

    git ls-tree -r HEAD | cut -f2 | while read f; do
        egrep -e '^(//|--) vim: .*encoding=' $f >/dev/null || continue
        sed -E -e '/^(\/\/|--) vim:/s/:encoding=utf-8//' $f > /tmp/foo
        mv /tmp/foo $f
    done

Uli Schlachter ab4c151ed8 Add signals before using them
This commit makes it an error if an unknown signal is connected, disconnected or
emitted. All signals have to be added before they can be used.
