MIPS: a.out, ecoff, and elf nlist support PowerPC: a.out and elf nlist support

/* $NetBSD: nlist_private.h,v 1.4 1997/03/29 21:02:47 thorpej Exp $ */
Seriously revamp libc's nlist()/__fdnlist() support: (1) split nlist() into multiple files, for clarity and to make ELF 32/64 support easier, (2) support multiple executable types at the same time, and (3) add support for 32- and 64-bit ELF (32-bit ELF support originally from OpenBSD, but with several bug fixes so that it actually handles symbols types more correctly (and therefore _works_ for some of the more tricky uses of the nlist routines) and changes for 64-bit ELF support).

slightly tune what gets compiled in: On the Alpha, we need ECOFF and ELF64. On other architectures only include a.out support, since we don't know whether or not they'll have the headers necessary for ECOFF and/or ELF, and since they only want a.out for now (execpt the mips archs, but they do Special things). There should be a better way to select which bits of nlist code get compiled in, but currently there is not.
