ubsan: signed integer overflow in display_debug_lines_raw
This one was caused by me unnecessarily promoting an "int adv" to "int64_t adv". The expression overflowing was 4259 + 9223372036854775807 with the left number being unsigned int. * dwarf.h (DWARF2_Internal_LineInfo): Replace unsigned short with uint16_t and unsigned char with uint8_t. Make li_line_base an int8_t. * dwarf.c (display_debug_lines_raw): Revert "adv" back to an int.
