Re: Move bfd_init to bfd.c

Re: Move bfd_init to bfd.c

Commit b1c95bc4dd73 resulted in
...bfd.texi:246: @include: could not find init.texi
which went unnoticed due to not building in a clean directory.

This fixes the problem by moving bfd_init earlier, giving it a
doc node, and stitching the nodes back together.

	* bfd.c (bfd_init): Move earlier.  Give it a doc inode.
	Adjust other inodes to suit.
	* doc/bfd.texi: Don't include init.texi.  Adjust nodes to suit.
