[Greg Hudson via RT]

Use k5_transport(_strategy) enums for k5_sendto

In k5_sendto and k5_locate_server, replace "socktype" parameters with
a new enumerator k5_transport, so that we can add new transports which
are not in the socket type namespace.  Control the order in which we
make connections of different types using a new k5_transport_strategy
enumerator, to simplify the logic for adding new transports later.
Control the result of k5_locate_server with a no_udp boolean rather
than a socket type.

[ghudson at mit.edu: renamed type to k5_transport; k5_locate_server
 no_udp change; clarified commit message; fix for Solaris getaddrinfo]
[kaduk at mit.edu: name variables of type k5_transport 'transport']
[nalin at redhat.com: use transport rather than sock_type in more places,
 add and use k5_transport_strategy, update the test program]
