Allocate memory storage for common variables such as the singular values and the basis vectors.

#include "slepcsvd.h" 
PetscErrorCode SVDAllocateSolution(SVD svd,PetscInt extra)

Collective

	svd	- eigensolver context
	extra	- number of additional positions, used for methods that require a working basis slightly larger than ncv

This is SLEPC_EXTERN because it may be required by user plugin SVD implementations.

This is called at setup after setting the value of ncv and the flag leftbasis.
