Zero supplied stat buffers in functions that pretend to stat
GDB has five places where it pretends to stat for bfd_openr_iovec.
Four of these only set the incoming buffer's st_size, leaving the
other fields unchanged, which is to say very likely populated with
random values from the stack. remote_bfd_iovec_stat was fixed in
0a93529c56714b1da3d7106d3e0300764f8bb81c; this commit fixes the
other four.
gdb/ChangeLog:
* jit.c (mem_bfd_iovec_stat): Zero supplied buffer.
* minidebug.c (lzma_stat): Likewise.
* solib-spu.c (spu_bfd_iovec_stat): Likewise.
* spu-linux-nat.c (spu_bfd_iovec_stat): Likewise.
