d5a23ce115 Move rend auth cookie en-/decoding to a function 
Tor stores client authorization cookies in two slightly different forms.
The service's client_keys file has the standard base64-encoded cookie,
including two chars of padding. The hostname file and the client remove
the two padding chars, and store an auth type flag in the unused bits.

The distinction makes no sense. Refactor all decoding to use the same
function, which will accept either form, and use a helper function for
encoding the truncated format.

03fc4cf04c Refactor router_pick_directory_server_impl to use node functions 
No behavioural change

This makes the use of the node explicit in the function, rather
than hiding the node lookup in fascist_firewall_allows_rs.

833b5f71a7 Make clients always use begindir for directory requests 
This improves client anonymity and avoids directory header tampering.
The extra load on the authorities should be offset by the fallback
directories feature.

This also simplifies the fixes to #18809.

Make directory node selection more reliable 
Delete an unnecessary check for non-preferred IP versions.

Allows clients which can't reach any directories of their
preferred IP address version to get directory documents.

Patch on #17840 in 0.2.8.1-alpha.

0cf90bac2a Choose the correct address for one-hop connections 
After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.

This likely affected bridge clients with IPv6 bridges.

Resolves #18921.

0ca3f495c6 Fix dnsserv.c assertion when no supported questions are requested. 
The problem is that "q" is always set on the first iteration even
if the question is not a supported question. This set of "q" is
not necessary, and will be handled after exiting the loop if there
if a supported q->type was found.

8f292f1c33 Fix keccak-tiny portability on exotic platforms. 
* SHA-3/SHAKE use little endian for certain things, so byteswap as
   needed.

 * The code was written under the assumption that unaligned access to
   quadwords is allowed, which isn't true particularly on non-Intel.
