[gdm-list] change gdm_address_new_from_sockaddr_storage to gdm_address_new_from_sockaddr

["Ray Strode" <halfline gmail com>]

Hi Jon,

The function gdm_address_new_from_sockaddr_storage gets called in a
few places with socket addresses that aren't necessary
sockaddr_storage bytes big (all the places that call getaddrinfo).
This results in the memdup call in that function potentially copying
out of bounds bytes.

We need to know how many bytes to copy, so we don't copy more than are
allocated, or less than the address type needs.

I've attached a patch to change

GdmAddress *
gdm_address_new_from_sockaddr_storage (sockaddr_storage *ss)

to

GdmAddress *
gdm_address_new_from_sockaddr (sockaddr *sa, size_t size)

--Ray
