r210331: Add a new ELF type denoting GNU style hash tables. r210332: Changes for supporting GNU Hash sections. r210333: Note that the *_fsize() functions are only defined for ELF types that have a fixed size. r210335: - Return zero for file sizes of ELF types that have a variable size. - Neaten a few comments. r210336: Reduce verbosity. r210338: 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. r210340: - Document that the *fsize() functions return a size of 1 for Elf types that don't have a fixed size. - The *fsize() functions should return a size of 1, for variable length types. - Redefine symbol ELF_T_LAST to match the current end of the list. r210341: Add support for translating sections of type ELF_T_GNUHASH. r210559: Protect GNUHASH translation functions with #ifdef; unbreak cross toolchain build.

MFC r210324, r210438.

r210324: - 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. - 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. r210438: (np) Catch up with r210324. d_buf will be NULL for SHT_NOBITS sections, do not attempt to copy from it in that case.

Correct a typo.
