Add autogenerated dependency info to Makefile.

Adds a .depend file containing dependency information generated by
makedepend, which is appended to the generated Makefile by configure.

You can regen the file with "make -f Makefile.in depend" if necessary,
but we'll be looking at some way to automatically keep this up to date.
