801e789e01 Update loader logic to distinguish modules vs. files.
Add support for module metadata. The old way of dependancy
handling will be supported for a while.

1d59e49683 Turn symbol table info passing back on, although it's probably not
particularly useful in this form.  KLD can deal with it much better.
setenv kernelname moved earlier.

5f8edb2c4d Don't include ELF symbol information yet - it causes the ELF DDB to
explode.

Allocate space for, and copy, NDOSPART slice entries from the
	MBR, not just one.  Add some extra debugging while we're at it.

bf72f68088 Consolidate the bootinfo-loading code, greatly simplifying the _exec
functions.

2e06076f23 First shot at loading elf symbols. Things are a bit strange because
of the ..umm.. "wierd" way binutils lays out the file.  The section
headers are nearly at the end of the file and this is a problem when
loading from a .gz file which can't seek backwards (or has a limited
reverse seek, ~2K from memory).

This is intended to be compatable with the ddb/db_elf.c code and the
alpha/libalpha/elf_freebsd.c layout.  I've studied these (which are NetBSD
derived) but did it a bit differently.  Naturally the process is similar
since it's supposed to end up with the same result.

d1a50365db i386 ELF loader startup backend. On an ELF kernel booted with the 3-stage
bootblocks, the kernel shows up as the primary module:

[3:24am]~-100# kldstat
Id Refs Address  Size     Name
 1    1 0xf0100000 ff00000  /kernel
		   ^^^^ oops.. :-)

Based heavily on aout_freebsd.c.  Hmm.. There's so much in common that
these could probably be combined and just check the metadata to see which
format it is.
