asan: heap buffer overflow printing ecoff debug info file name
A case of a string section ending with an unterminated string. Fix it
by allocating one more byte and making it zero. Also make functions
reading the data return void* so that casts are not needed.
* ecoff.c (READ): Delete type param. Allocate one extra byte
to terminate string sections with a NUL. Adjust invocation.
* elfxx-mips.c (READ): Likewise.
* libbfd-in.h (_bfd_alloc_and_read): Return a void*.
(_bfd_malloc_and_read): Likewise.
* libbfd.h: Regenerate.
