69347f48e0 Disable consensus methods before 25.
Consensus method 25 is the oldest one supported by any stable
version of 0.2.9, which is our current most-recent LTS.  Thus, by
proposal 290, they should be removed.

This commit does not actually remove the code to implement these
methods: it only makes it so authorities will no longer support
them.  I'll remove the backend code for them in later commits.

f1c1328f85 Repair the legacy_hs/pick_tor2web_rendezvous_node unit test
It tried to pick nodes for which only routerinfo_t items are set,
but without setting UseMicroDescriptors to 0.  This won't work any
more, now that we're strict about using the right descriptor types
due to 25691/25692/25213.

47163780c3 Rename node_has_descriptor() to node_has_any_descriptor()

it when node_has_preferred_descriptor() would be more appropriate.

2d7b5c6fe5 Change the type of "download schedule" from smartlist to int.
This is done as follows:
  * Only one function (find_dl_schedule()) actually returned a
    smartlist. Now it returns an int.

  * The CSV_INTERVAL type has been altered to ignore everything
    after the first comma, and to store the value before the first
    comma in an int.

3bf9974b6c Fix a pointer size error in test_bridges.c
sizeof(ret) is the size of the pointer, not the size of what it
points to.  Fortunately, we already have a function to compare
tor_addr_port_t values for equality.

Bugfix on c2c5b13e5d8a77e; bug not in any released Tor. Found by
clang's scan-build.

93ff1870ba heartbeat: Log the number of circuits killed because too many cells
We recently merged a circuit cell queue size safeguard. This commit adds the
number of killed circuits that have reached the limit to the DoS heartbeat. It
now looks like this:

  [notice] DoS mitigation since startup: 0 circuits killed with too many
  cells. 0 circuits rejected, 0 marked addresses. 0 connections closed. 0
  single hop clients refused.

Second thing that this patch does. It makes tor always print the DoS
mitigation heartbeat line (for a relay) even though no DoS mitigation have
been enabled. The reason is because we now kill circuits that have too many
cells regardless on if it is enabled or not but also it will give the operator
a chance to learn what is enabled with the heartbeat instead of suddenly
appearing when it is enabled by let say the consensus.

Fixes #25824

003e6595bf Refactor "timestamp" not to be its own type coupled to token buffers
Really, the uint32_t is only an optimization; any kind of unit
should work fine.  Some users might want to use time_t or
monotime_coarse_t or something like that.

0b40ed5e70 Start re-refactoring the token bucket interface.
Begin by creating a lowest-level triple of the types needed to
implement a token bucket: a configuration, a timestamp, and the raw
bucket itself.

Note that for low-level buckets, the units of the timestamp and the
bucket itself are unspecified: each user can use a different type.

(This patch breaks check-spaces; a later patch will fix it)

03b96882de Rename token_bucket_t to token_bucket_rw_t.
This is a simple search-and-replace to rename the token bucket type
to indicate that it contains both a read and a write bucket, bundled
with their configuration.  It's preliminary to refactoring the
bucket type.

62f4d5a265 Add a unit test for post-loop events
This test works by having two post-loop events activate one another
in a tight loop.  If the "post-loop" mechanism didn't work, this
would be enough to starve all other events.

c376200f6a Add a new token-bucket backend abstraction, with tests
This differs from our previous token bucket abstraction in a few
ways:

  1) It is an abstraction, and not a collection of fields.
  2) It is meant to be used with monotonic timestamps, which should
     produce better results than calling gettimeofday over and over.

46795a7be6 Attempt to fix 32-bit clang builds, which broke with 31508a0abc
When size_t is 32 bits, the unit tests can't fit anything more than
4GB-1 into a size_t.

Additionally, tt_int_op() uses "long" -- we need tt_u64_op() to
safely test uint64_t values for equality.

31508a0abc Use less memory for MaxMemInQueues for machines with more than 8 GB of RAM.
This patch changes the algorithm of compute_real_max_mem_in_queues() to
use 0.4 * RAM iff the system has more than or equal to 8 GB of RAM, but
will continue to use the old value of 0.75 * RAM if the system have less
than * GB of RAM available.

This patch also adds tests for compute_real_max_mem_in_queues().
