Adjusted denomintor degress freedom for linear estimate for linear mixed model.

Get adjusted denomintor degress freedom for testing L'beta=0 in a linear mixed model.

get_ddf_Lb(object, Lcoef)
ddf_Lb(VVa, Lcoef, VV0=VVa)

`object`	A linear mixed model object.
`Lcoef`	A vector with the same length as `fixef(object)`
`VVa, VV0`	Adjusted and unadjusted covariance matrix for the fixed effects parameters. Adjusted covariance matrix is obtained with `vcovAdj()` and the unadjusted with `vcov()`.

Adjusted degrees of freedom (adjusment made by a Kenward-Roger approximation).
