Creation of second derivative xc-potential.

Parameters

qs_env	...
vxc	will contain the partially integrated second derivative taken with respect to rho, evaluated in rho and folded with rho1 vxc is allocated here and needs to be deallocated by the caller.
vxc_tau	...
rho	density at which derivatives were calculated
rho1_r	density in r-space with which to fold
rho1_g	density in g-space with which to fold
tau1_r	...
xc_section	XC parameters of this potential
compute_virial	Enable stress-tensor calculation
virial_xc	Will contain GGA contribution of XC-kernel to stress-tensor
