More fixes for memory access errors when running readelf on fuzzed binaries.
PR binutils/17531
* dwarf.c (process_debug_info): Check for abbrev_base being larger
than the section size.
(process_cu_tu_index): Use xcalloc2 to allocate the CU and TU
arrays.
(xcalloc2): New function. Like xcalloc, but checks for overflow.
* dwarf.h (xcalloc2): Prototype.
