core: add "fatal-warnings" option to NM_DEBUG

Browse Source 
NM already understands the command line argument --g-fatal-warnings
which causes setting of g_log_set_always_fatal().

Also interpret the "fatal-warnings" token in NM_DEBUG environment
variable and in main.debug configuration setting.

Usage hint: either set

  $ export NM_DEBUG=RLIMIT_CORE,fatal-warnings

or add the following section to NetworkManager.conf

    [main]
    debug=RLIMIT_CORE,fatal-warnings
