Having these variables set enables apps to discrimination
against ladish, by error or otherwise. In particular
neither LADISH L0 nor L1 imply that user should face mayhem
of standard file menu items for either new, open, save
and/or saveas being disabled.
The exit code detection for apps ran in terminal is not working,
at least with xterm. xterm doesnt seem to be able to return exit
code of its child process.
* code for the service lifecycle object moved to main.c - remove polution by fake OO concept
* removed types.h - typedefs for public structs are evil. typedefs for handles must be per header
* compile with -Wall and -Werror flags. Warnings are here to help.
* define _GNU_SOURCE globally, in config.h. This is propoerty of the whole daemon codebase.
* common.h is header to collect stuff that is needed almost everywhere in the ladishd
* cleanup loader module.
