Improve the propagation of function domain error handling in SNES, especially in the line search routines.

Due to the object layering of SNESLineSearch under SNES there is some code duplication include both SNESLineSearchReason and SNESConvergedReason and SNESCheckFunctionNorm() and SNESLineSearchCheckFunctionNorm() and Jacobian friends

SNESLinesearch: Minor improvements

- add missing configuration options in the documentation of the line searches (some of the available options were not listed), and consistently list their respective default values

- add proper convergence criteria for the secant method in the L2 line search based on ltol and atol (otherwise, the secant method is mostly running for the maximum number of iterations)

- fix a small bug in the CP line search, where steptol * lambda was used to check for convergence based on the change of lambda instead of the ltol parameter

- rename sneslinesearch->maxstep to sneslinesearch->maxlambda in the options database to be consistent with its purpose in the algorithms

- rename SNESLineSearchL2 to SNESLineSearchSecant to better represent its underlying approach

This shortens paths and improves consistency between test target names
and paths to the source and output files. Most of the work was
completed by this script, followed by mild cleanup of nonconforming
cases.
