Alan Modra 7a6e0d89bb Don't use bfd_get_file_size in objdump 
Compressed debug sections can have uncompressed sizes that exceed the
original file size, so we can't use bfd_get_file_size.  objdump also
used bfd_get_file_size to limit reloc section size, but I believe the
underlying bug causing the PR22508 out of bounds buffer access was
that we had an integer overflow when calculating the reloc buffer
size.  I've fixed that instead in most of the backends, som and
vms-alpha being the exceptions.  SOM and vmd-alpha have rather more
serious bugs in their slurp_relocs routines that would need fixing
first if we want to fuss about making them safe against fuzzed object
files.

The patch also fixes a number of other potential overflows by using
the bfd_alloc2/malloc2/zalloc2 memory allocation functions.
