Perform additional checks when translating between file and memory representations of ELF types.
The ELF(3) API allows applications to request a conversion that is `in-place', i.e., with source and destinations data buffers being the same. However, the file and memory sizes of ELF sections that have additional internal structure, such as those of type `Elf_Note', or `Elf_GNU_Hash_Header', can be determined only known after the type-specific headers that comprise the first few words in these sections are read and translated.
Pass in the size of destination buffer to type translation routines in "libelf_convert.m4" and have these routines return an error code if the translated data would not fit inside the destination buffer.
