Allow to validate the config file without X.
Patch status: merged
Patch by aszlig
We're going to call parse_configuration() very early if -C is given on the command line. Instead of the previous "only_check_config", which has been a global variable, we now simply pass use_nagbar as false if we're just validating. This causes the whole parsing to run without X and of course without starting nagbar and displaying the errors to standard out/error instead. The return code of parse_configuration() is now a boolean which represents whether an error occured during parsing and the programs exit code is returned accordingly. Although the config parser still has a lot of side-effects, we now can parse without the need to have an XCB connection. A nicer implementation would be to just set the new font and load it just after we're done parsing, but to ensure we don't break functionality we just load a dummy FONT_TYPE_NONE if XCB isn't available. The main reason for going this route is that it's a bit difficult to test fonts in a distribution agnostic way without bundling fonts with i3 (or Xdummy to be more exact).
