psblas3:
Updated license statement on all files in preparation for 3.0 release. Defined i_base_vect and i_vect; also to get through with preprocessing defined idot and inrm2 even if they are not actually used (and inrm2 really does norm1).psblas-3.0-maint

|

! This module contains the definition of the psb_i_base_vect type which
|

! is a container for dense vectors.
|

! This is encapsulated instead of being just a simple array to allow for
|
||||
! more complicated situations, such as GPU programming, where the memory
|
||||
! area we are interested in is not easily accessible from the host/Fortran
|
||||
! side. It is also meant to be encapsulated in an outer type, to allow
|
||||
! runtime switching as per the STATE design pattern, similar to the
|
||||
! sparse matrix types.
