Nick Mathewson 4f8086fb20 Enable -Wnull-dereference (GCC >=6.1), and fix the easy cases
This warning, IIUC, means that the compiler doesn't like it when it
sees a NULL check _after_ we've already dereferenced the
variable. In such cases, it considers itself free to eliminate the
NULL check.

There are a couple of tricky cases:

One was the case related to the fact that tor_addr_to_in6() can
return NULL if it gets a non-AF_INET6 address.  The fix was to
create a variant which asserts on the address type, and never
returns NULL.

Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.

To build Tor from source:
        ./configure && make && make install

To build Tor from a just-cloned git repository:
        sh autogen.sh && ./configure && make && make install
