Remove longclaw's IPv6 address, as it will soon change
Authority IPv6 addresses were originally added in 0.2.8.1-alpha.

This leaves 3/8 directory authorities with IPv6 addresses, but there
are also 52 fallback directory mirrors with IPv6 addresses.

Resolves 19760.

7cc9621d11 sched: Add Schedulers torrc option
This option is a list of possible scheduler type tor can use ordered by
priority. Its default value is "KIST,KISTLite,Vanilla" which means that KIST
will be used first and if unavailable will fallback to KISTLite and so on.

b2c56eacdd sched: Remove vanilla sched options that will be going away
- massive change to src/tgest/test_options.c since the sched options
  were added all over the place in it
- removing the sched options caused some tests to pass/fail in new ways
  so I assumed current behavior is correct and made them pass again
   - ex: "ConnLimit must be greater" lines
   - ex: "Authoritative directory servers must" line
- remove test_options_validate__scheduler in prep for new sched tests

93a8ed3b83 Make clients wait to refresh bridges when they have a recent descriptor
But when clients are just starting, make them try each bridge a few times
before giving up on it.

These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)

Fixes 23347, not in any released version of tor.

97249c4f5e Make bridge clients download bridge descriptors immediately
The download schedule tells Tor to wait 15 minutes before downloading
bridge descriptors. But 17750 made Tor ignore that and start immediately.
Since we fixed 17750, Tor waits 15 minutes for bridge client bootstrap,
like the schedule says.

This fixes the download schedule to start immediately, and to try each
bridge 3 times in the first 30 seconds. This should make bridge bootstraps
more reliable.

Fixes 23347.

02e2edeb33 prop224: Add hs_config.{c|h} with a refactoring
Add the hs_config.{c|h} files contains everything that the HS subsystem needs
to load and configure services. Ultimately, it should also contain client
functions such as client authorization.

This comes with a big refactoring of rend_config_services() which has now
changed to only configure a single service and it is stripped down of the
common directives which are now part of the generic handler.

This is ground work for prop224 of course but only touches version 2 services
and add XXX note for version 3.

b867295ffd config: Parse ports at the start of options_validate()
There was a bug that got exposed with the removal of ORListenAddress. Within
server_mode(), we now only check ORPort_set which is set in parse_ports().

However, options_validate() is using server_mode() at the start to check if we
need to look at the uname but then the ORPort_set is unset at that point
because the port parsing was done just after. This commit fixes that.

b0e92634d8 Netflow record collapsing defense.
This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.

Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.

The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.

The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.

Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.

c2d1d949de Use tor_compress_supports_method() before printing library versions.
This patch ensures that Tor checks if a given compression method is

Additionally, we use the `tor_compress_supports_method()` to check if a
given version is supported for Tor's start-up version string, but here
we print "N/A" if a given compression method is unavailable.

Make MAX_DIR_PERIOD independent of MIN_ONION_KEY_LIFETIME.
As part of the work for proposal #274 we are going to remove the need
for MIN_ONION_KEY_LIFETIME and turn it into a dynamic value defined by a
consensus parameter.

83df359214 config: Stop recommending Tor2web if in non anonymous mode
Because we don't allow client functionalities in non anonymous mode,
recommending Tor2web is a bad idea.

If a user wants to use Tor2web as a client (losing all anonymity), it should
run a second tor, not use it with a single onion service tor.

Fixes #21294.

51b562c605 Use an internal variable for HiddenServiceStatistics
Stop modifying the value of our torrc option HiddenServiceStatistics just
because we're not a bridge or relay. This bug was causing Tor Browser users to
write "HiddenServiceStatistics 0" in their torrc files as if they had chosen
to change the config.

Fixes #21150
