libdwarf-code/libdwarf/dwarf_errmsg_list.c
David Anderson acae971371 added new error code 
libdwarf/dwarf_errmsg_list.c
libdwarf/libdwarf.h.in

Test for inconsistent line table header data
and provide a default string indicating failure
in case the inconsistency test is inadequate.

define is added to the list in libdwarf.h, a string should be
added to this Array
Errors in the list (missing a comma, for example)
happen too often. Making this a separate little file
