This function is used to resize the faces array of a mesh.
If local is not zero, local_faces will also be allocated.
If keep is not zero, the newly allocated array will contain the data
from previous faces array.
If new number of faces is bigger then original face count, all old faces are
maintained.
If new number of faces is smaller then original face count, only the first nfaces
faces will be kept.
