When creating a routerstatus (vote) from a routerinfo (descriptor),
set the IPv6 address to the unspecified IPv6 address, and explicitly
initialise the port to zero.
Also clarify the documentation for the function.
Fixes bug 24488; bugfix on 0.2.4.1-alpha.

Implements #23826.

And pass ROUTERSTATUS_FORMAT_NO_CONSENSUS_METHOD when it's not applicable.
Preparation for #23826.

Before, this function meant "can we connect to this node and
authenticate it using its ed25519 key?" Now it can additionally
mean, "when somebody else connects to this node, do we expect that
they can authenticate using the node's ed25519 key"?
This change lets us future-proof our link authentication a bit.
Closes ticket 20895. No backport needed, since ed25519 link
authentication support has not been in any LTS release yet, and
existing releases with it should be obsolete before any releases
without support for linkauth=3 are released.

Our convention is that functions which manipulate a type T should be
named T_foo. But the buffer functions were super old, and followed
all kinds of conventions. Now they're uniform.
Here's the perl I used to do this:
\#!/usr/bin/perl -w -i -p
s/read_to_buf\(/buf_read_from_socket\(/;
s/flush_buf\(/buf_flush_to_socket\(/;
s/read_to_buf_tls\(/buf_read_from_tls\(/;
s/flush_buf_tls\(/buf_flush_to_tls\(/;
s/write_to_buf\(/buf_add\(/;
s/write_to_buf_compress\(/buf_add_compress\(/;
s/move_buf_to_buf\(/buf_move_to_buf\(/;
s/peek_from_buf\(/buf_peek\(/;
s/fetch_from_buf\(/buf_get_bytes\(/;
s/fetch_from_buf_line\(/buf_get_line\(/;
s/fetch_from_buf_line\(/buf_get_line\(/;
s/buf_remove_from_front\(/buf_drain\(/;
s/peek_buf_startswith\(/buf_peek_startswith\(/;

Telling these functions to autodetect the numeric base has lead to

This patch ensures that the published_out output parameter is set to the
current consensus cache entry's "valid after" field.

As of ac2f6b608a18a8595f62384788196d7c3f2875fd in 0.2.1.19-alpha,
Sebastian fixed bug 888 by marking descriptors as "impossible" by
digest if they got rejected during the
router_load_routers_from_string() phase. This fix stopped clients
and relays from downloading the same thing over and over.
But we never made the same change for descriptors rejected during
dirserv_add_{descriptor,extrainfo}. Instead, we tried to notice in
advance that we'd reject them with dirserv_would_reject().
This notice-in-advance check stopped working once we added
key-pinning and didn't make a corresponding key-pinning change to
dirserv_would_reject() [since a routerstatus_t doesn't include an
ed25519 key].
So as a fix, let's make the dirserv_add_*() functions mark digests
as undownloadable when they are rejected.
Fixes bug 22349; I am calling this a fix on 0.2.1.19-alpha, though
you could also argue for it being a fix on 0.2.7.2-alpha.

When directory authorities reject a router descriptor due to keypinning,
free the router descriptor rather than leaking the memory.

Directory authorities now reject relays running versions
0.2.9.1-alpha through 0.2.9.4-alpha, because those relays
suffer from bug 20499 and don't keep their consensus cache
up-to-date.
Resolves ticket 20509.

"You're running 0.2.2; upgrade!" is more sensible than "You have no

These are mostly just identifier renames, except for one place in
routerparse.c where we switch to using a correct hash.

Also store it in the cached_dir_t.

This patch refactors our streaming compression code to allow us to
extend it with non-zlib/non-gzip based compression schemas.

To allow us to use the API name `tor_compress` and `tor_uncompress` as
the main entry-point for all compression/uncompression and not just gzip
and zlib.

The old implementation had duplicated code in a bunch of places, and
it interspersed spool-management with resource management. The new
implementation should make it easier to add new resource types and
maintain the spooling code.
