Uli Schlachter af8288335b Use command line instead of env for passing children
Commit e54361a374 added code so that we pass the list of
currently running children across restart via an environment variable.
As Colin Walters correctly points out, setenv() is not safe in a
multi-threaded processes.

Thus, instead of using the environment, use the command line to pass
this information along.

Uli Schlachter e54361a374 Reap children even across a restart
In Unix, so that a process can learn about the exit status of the child
processes that it started, children become zombie processes until the
parents collects their exit information. We use glib both for starting
and for collecting processes. However, when awesome is restarted, the
new instance inherits children, but does not know about them and does
not inherit them.

Fix this by explicitly tracking a list of running child processes and by
serialising them across a restart via an environment variable. The new
awesome instance can then watch for these child processes, but besides
that it ignores them and does not use their exit status in any way.

Thanks to Colin Walters for the hint with serialising the list of processes.

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This option is no longer valid in modelines, so it has been removed from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 d31b7666a1 spawn: add spawn_system() which works like system()
This adds a small function which behaves exactly like libc's system(), but also
clears the masked signal set in the child process.

This is needed because libev 3.8 masks signals. :(
