Correctly free reloc and contents memory.

Replace occurrences of "_raw_size" and "_cooked_size" in most places

sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".
