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.
