[CppAD] Some math functions don't seem to be defined for AD<AD<double>> types

[Brad Bell]

Sorry about that. I forgot some of the standard math functions in 
cppad/local/std_math_ad.hpp. I have modified the automated tests so that 
this should not happen again. The changes are check in; see
    https://projects.coin-or.org/CppAD/changeset/1092
and immediately available when using Subversion to dowload CppAD. They 
will be available from the tar files early tomorrow morning.
