Author: Jeffrey Stedfast <fejj gnome org>

    Optimized g_mime_strdup_trim() and updated parser to use it
    
    2012-02-20  Jeffrey Stedfast  <fejj gnome org>
    
    	* gmime/gmime-common.c (g_mime_strdup_trim): Optimized.
    
    	* gmime/gmime-parser.c (header_parse): Use g_mime_strdup_trim()
    	instead of reimplementing the same logic here.
