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.

- Correctly handle sections of type SHT_NOBITS. For these sections:

- elf_getdata() and elf_rawdata() should return an "Elf_Data" structure that has its "d_buf" member set to NULL and "d_size" member set to the nominal 'size' of the section. [1] - Update the manual page for these functions. - Fix a memory leak in an error handling path inside elf_getdata(). - Use _libelf_allocate_data() in elf_newdata() for consistency.

Correct a typo.
