SNES: Removed now-extraneous fnorm variable from SNESApplyPC()

Since c1c75074e128c85b53ed5ce1f9b329b0e4d789b9 the fnorm argument
has been unused. Fix documentation also.

removed use of SNESFunction, SNESJacobianFunction etc as names in function arguments

Sys: add PetscMalloc1 macro, array allocation without redundant types

The type is inferred from the pointer return type. This patch is
automated via the following script:

git grep -l 'PetscMalloc(.*sizeof' src | xargs perl -pi -e 's@PetscMalloc\(([^,;]*[^,; ]) *\* *sizeof\([^,;()]+\),@PetscMalloc1($1,@'

This commit contains an additional bug-fix in csrperm.c, fixing pointer
arity. The code was introduced in 2006, but the allocation could not
have been correct at any time. This probably means that
MatDuplicate_SeqAIJPERM has never been tested.

Added MATSEQCSRPERM support for MatDuplicate() and conversion to/from
MATSEQAIJ. Note that these changes are not quite debugged.
