    eliminate g_error() usage · 28bcb8bd
    Thomas Jansen authored
    Replaced all occurrences of g_error() with MPD_ERROR() located in a new header
    file 'mpd_error.h'. This macro uses g_critical() to print the error message
    and then exits gracefully in contrast to g_error() which would internally call
    abort() to produce a core dump.
    
    The macro name is distinctive and allows to find all places with dubious error
    handling. The long-term goal is to get rid of MPD_ERROR() altogether. To
    facilitate the eventual removal of this macro it was added in a new header
    file rather than to an existing header file.
    
    This fixes #2995 and #3007.
