SNESGetLineSearch / SNESSetLineSearch: rename for consistency

This function was introduced as SNESGetPetscLineSearch, which matches no
established convention, then changed to SNESGetSNESLineSearch according
to the object name SNESLineSearch. This is inconsistent with names such
as MatGetInfo, MatGetColoring, MatGetNullSpace, MatGetLocalToGlobalMapping,
SNESGetConvergedReason, and TSGetAdapt.

This is a change from petsc-3.3.

SNESGetSNESLineSearch: use auto Fortran binding

removed unnneeded and unused XXXRegisterDestroy() routines

removed PetscFunctionListDestroyAll() and put PetscFunctionListDestroy(&XXXList) into the package finalize

Fixes for MATLAB interface. (1) Fixed MPIUni to be reentrant again, (2) fixed PetscSF to be reentrant

SNESSetCountersReset() lets SNES to keep nfuncs and linear_its for many solves

Fix to RHS bug in nonlinear left preconditioning

Control over initial SNES func/norm in one place; inner ASPIN fix.

Added SNESGet/SetLagJacobian/PreconditionerPersists()

Lags through several solves -- good for preconditioners, good for timestepping.

Doc fixes in snesob.c, anderson.c, snesngmres.c

PetscFunctionListAdd: use macro to hide (PetscVoidFunction) cast

Same rationale as the last commit:

Casting using PetscVoidFunction instead of (void(*)(void)) is needed
with C++ compilers that will not implicitly convert C++ language linkage
to C language linkage. Since PetscFunctionListAdd() is meant to operate
on generic function pointers, we hide this language linkage detail
(which is inconsistently implemented) in a cast.
