qt4: use preprocessor flags with moc, so it finds the headers in the right place

Fix hang in live555 when sending RTSP OPTIONS by letting readSocket() timeout after 5 seconds. Added reconnect case to modules/demux/live555.cpp (without backing off scenario).

(Modules that would still depend on module_config_t are not going to like this, but it's not like you weren't warned a long time ahead)

Really fix charset for http-lua pages (--[[ ]] are block comments in lua so anything inside those isn't taken into account)

This is very likely to break .*64 platforms.

Add option to reset controls to their default value at runtime. Add "controls-update" variable which is triggered if any of the controls value is changed. Add some comments and change some function names.

Add v4l2 section in extended pannel. The code isn't v4l2 specific at all so it could be adapted for other modules (as long as those define the "controls" variables with a list of controls that can be changed at runtime).

Rework the v4l2 control handling. Variables corresponding to controls don't have any v4l2 suffix anymore. Variables for custom controls are also created. See "vars v4l2" in the rc interface. The "controls" variables is a list of all controls available. Next step is to use all these changes in the Qt interface to create a v4l2 control pannel.

Add VLC_VAR_GET{MIN,MAX,STEP} commands. Make it possible to use VLC_VAR_INHERITVALUE with a 2nd argument which will be used as the variable name to inherit (for example you want to inherit a variable named "v4l2-hue" into a variable named "hue": vlc_value_t val; val.psz_string = strdup( "v4l2-hue" ); var_Change( p_demux, "hue", VLC_VAR_INHERITVALUE, NULL, &val ); free( val.psz_string ); )

Qt4 - MediaInfoPanel, fix a segfault and don't clear() everytime you update and there is no input. :D
