If section content hasn't been read yet, do it before looking for the
block size. If no section data present, infer size of section header.

+ * elf32_getphdr.c (elfw2(LIBELFBITS,getphdr)): Check if program header
+ table fits into object's bounds.
+ * elf_getshstrndx.c (elf_getshstrndx): Add elf->start_offset to
+ elf->map_address. Check if first section header fits into object's
+ bounds.
+ * elf32_getshdr.c (elfw2(LIBELFBITS,getshdr)):
+ Check if section header table fits into object's bounds.
+ * elf_begin.c (get_shnum): Ensure section headers fits into
+ object's bounds.
+ (file_read_elf): Make sure scncnt is small enough to allocate both
+ ElfXX_Shdr and Elf_Scn array. Make sure section and program header
+ tables fit into object's bounds. Avoid memory leak on failure.
