I introduced this bug when I moved signing_key_cert into
signed_descriptor_t. Bug not in any released Tor. Fixes bug 19175, and
another case of 19128.
Just like signed_descriptor_from_routerinfo(), routerlist_reparse_old()
copies the fields from one signed_descriptor_t to another, and then
clears the fields from the original that would have been double-freed by
freeing the original. But when I fixed the s_d_f_r() bug [#19128] in
50cbf22099, I missed the fact that the code was duplicated in
r_p_o().
Duplicated code strikes again!
For a longer-term solution here, I am not only adding the missing fix to
r_p_o(): I am also extracting the duplicated code into a new function.
Many thanks to toralf for patiently sending me stack traces until
one made sense.
