SNESLinesearchSetFunction() for setting what function the line search uses

Fix in documentation to SNESLineSearchShellSetUserFunc()

Arguments in the example code were reversed. I also styled it better.

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.

LOCDIR: fix all outdated paths and normalize trailing slash

Update performed by:

git ls-files '*/makefile' | xargs perl -pi -MFile::Basename \

git ls-files '*/makefile' | xargs perl -pi -MFile::Basename \
-e 's!(LOCDIR[[:space:]]+=) *(.+)$!$1." ".dirname($ARGV)."/"!e'

Fortran auto must be fixed using 'make allfortranstubs' and the result
can be checked by 'bin/maint/checkloc.py'.

line search should not seterrq() on Nan or Inf but rather set line search failed and return

Hg-commit: 97a95f7942dc812c40012e0b79526d52788f3843

added PetscObjectComm() and used it to replace (((PetscObject)obj)->comm)

Hg-commit: 3da37c458124ad48ae939f4e9823e4430ee0b8be

removed PETSC_NULL from C and Fortran (except declaration in C for backward compatibility). Kept PETSC_NULL_xxx for Fortran
Fixed a few bugs where PETSC_NULL had been used incorrectly.
