Kevin O'Connor ccc8fe2fc5 itersolve: Convert iterative solver to use "secant method" ...

The previous code calculates each step time via an "exponential
search" followed by a "false position with Illinois algorithm" search.
Replace with a "secant method" with "bounds check" search.  This
simplifies the code, improves the performance, and does a better job
of finding steps near a direction change.
