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

Slightly improved the handling of PCFailedReason on multiple ranks

pc->failedreasonrank now contains the failed reason from the current rank
pc->failedreason continues the unified common value collected in KSPCheckNorm/Dot
This parallel code can check the common value and be sure to do the same action on each process
Also printed message now provide the accurate value instead of the value on rank 0

Changed KSPReasonView() and KSPReasonViewFromOptions() to KSPCOnvergeReasonView() and KSPConvergedReasonViewFromOptions()

Added the PetscViewerFormat argument to the public KSPReasonViewFromOptions() and removed the private function

Removed some off the PCFailedReaon processing code from KSPSolve_PREONLY since buggily assumed the same reason all ranks

The error message on KSP failure now also prints the PCFailedReason if appropriate

Needed to add a new alt file
