Remove iterate_over_inferiors

The last caller of iterate_over_inferiors is darwin-nat.c.  This patch
removes the calls from this file, and then remove
iterate_over_inferiors.

In general I think "external iteration" is to be preferred in gdb, the
main benefit being that the code is easier to read.

I rebuilt this on Darwin.  I seem to only have access to Darwin
systems where gdb does not yet work :-(, so I can't run the test
suite.
