libelf: Use a red-black tree to manage the section list.

The tree is indexed by section number.  This speeds up elf_getscn()
and its callers, which previously had to traverse a linked list. In
particular, since .shstrtab is often the last section in a file,
elf_strptr() would have to traverse the entire list.
