Then, there are two solutions:

1. Make c_value_of_variable and friends accept struct value as opposed to taking
struct varobj.
2. Extra the part of c_value_of_variable that you've based your function on
into a separate function. Make both c_value_of_variable and install_new_value
call the new function.

I'm not sure which approach you find better, but I don't think copy-pasting is a solution
to anything.
