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

Change matrix factor database options that occur in KSP/PC to always use KSP/PC options prefix

Add MatSetOptionsPrefixFactor() and MatAppendOptionsPrefixFactor() to allow controlling the options prefix
used by factors created from this matrix

Change MatSetOptionsPrefix() to no longer affect the options prefix used by factors created from this matrix

As part of the above work the handling of the factor matrix options is now done in code in the factor matrix
not in the code that originates the factor matrix

Update examples output to the new approach where the factored matrix prefix is set from the KSP/PC

Much of this work was performed by Hong Zhang
