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

As of ac2f6b608a 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.
Fixes bug 22370; bugfix on 0.2.7.2-alpha.
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.

This patch refactors our streaming compression code to allow us to
extend it with non-zlib/non-gzip based compression schemas.
See https://bugs.torproject.org/21663
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.
Closing ticket 21651.
This patch removes the `tor_fgets()` wrapper around `fgets(3)` since it
is no longer needed. The function was created due to inconsistency
between the returned values of `fgets(3)` on different versions of Unix
when using `fgets(3)` on non-blocking file descriptors, but with the
recent changes in bug #21654 we switch from unbuffered to direct I/O on
non-blocking file descriptors in our utility module.
We continue to use `fgets(3)` directly in the geoip and dirserv module
since this usage is considered safe.
This patch also removes the test-case that was created to detect
differences in the implementation of `fgets(3)` as well as the changes
file since these changes was not included in any releases yet.

Teor thinks that this connection_dirserv_add_dir_bytes_to_outbuf()
might be the problem, if the "remaining" calculation underflows. So
I'm adding a couple of checks there, and improving the casts.
Previously the dirserv_orconn_tls_done() function would skip routers
when they advertised an ed25519 key but didn't present it during the
link handshake. But that covers all versions between 0.2.7.2-alpha
and 0.2.9.x inclusive!
Fixes bug 21107; bugfix on 0.3.0.1-alpha.
Back when Roger had do do most of our testing on the moria host, we
needed a higher limit for the number of relays running on a single
IP address when that limit was shared with an authority. Nowadays,
the idea is pretty obsolete.
Also remove the router_addr_is_trusted_dir() function, which served
no other purpose.
Closes ticket 20960.
If there is some horrible bug in our ed25519 link authentication
code that causes us to label every single ed25519-having node as
non-running, we'll be glad we had this. Otherwise we can remove it
later.
This patch makes two absolutely critical changes:
- If an ed25519 identity is not as expected when creating a channel,
we call that channel unsuccessful and close it.
- When a client creating a channel or an extend cell for a circuit, we
only include the ed25519 identity if we believe that the node on
the other side supports ed25519 link authentication (from
#15055). Otherwise we will insist on nodes without the right
link protocol authenticating themselves.
- When deciding to extend to another relay, we only upgrade the
extend to extend by ed25519 ID when we know the ed25519 ID _and_
we know that the other side can authenticate.
This patch also tells directory servers, when probing nodes, to
try to check their ed25519 identities too (if they can authenticate
by ed25519 identity).
Also, handle the case where we connect by RSA Id, and learn the
ED25519 ID for the node in doing so.
