case insesitive version of strstr. Used from camel

2005-01-26  Sivaiah Nallagatla <snallagatla@novell.com>

       * util/eab-book-util.c (strstrcase) :
       case insesitive version of strstr. Used
       from camel

       (eab_contact_list_from_string) : do case in sensitive
       search for "BEGIN:VCARD" and "END:VCARD" to
       take care of broken vcards

       Fixes #70339
