When awesome calls any Lua code, it does so with a protected call. This
means that any kind of Lua error should (there are exceptions) just
result in an error message being printed and everything continuing as
usual. When LGI calls Lua code, it uses a normal call. This means that
in an asynchronous context, that is, when there is no more call
generated by awesome's C code on the call stack, we must be careful,
since any error results in Awesome's unprotected error handler to be
called which restarts the WM.
menubar.utils.parse_dir() asynchronously parses a directory containing
.desktop files. This means that it is no longer in a protected call
context. Let's assume that the code itself is fine. However, the
callback that the caller provided for handling the results can be quite
arbitrary. Make sure that it is run in a protected context.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

When not including standard::type in the query for children of a file then Gio
may not look up this information. This might work on some file systems (e.g.
ext4), but other (apparently XFS) do not provide the needed file type
information (see man readdir on the d_type field). The result was that the
menubar contained no entries because no .desktop files were identified as
regular files and thus read.
Fix this by including standard::type in the queries.
Also, this commit makes the code use some pre-defined string constants from Gio
to make "double sure" that typos are caught.
Thanks to @Jajauma for doing the hard part on debugging this.

It was missing apps/entries from /usr/share/applications/kde4.
This patch also makes sure that entries are unique (by Exec/Name).
Closes https://github.com/awesomeWM/awesome/pull/711.
