dff50001ec prop224: Flag router with HSIntro/HSDir using protover
Note down in the routerstatus_t of a node if the router supports the HSIntro=4
version for the ed25519 authentication key and HSDir=2 version for the v3
descriptor supports.

8aa69a1b69 Refactor the directory spool implementation
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.

946ccf3e4d Check onion key consensus parameters every hour.
This patch changes the way we decide when to check for whether it's time
to rotate and/or expiry our onion keys. Due to proposal #274 we can now
have the keys rotate at different frequencies than before and we thus
do the check once an hour when our Tor daemon is running in server mode.

This should allow us to quickly notice if the network consensus
parameter have changed while we are running instead of having to wait
until the current parameters timeout value have passed.

d88f10cdf2 Add API to query the current onion key grace period.
This patch adds an API to get the current grace period, in days, defined
as the consensus parameter "onion-key-grace-period-days".

As per proposal #274 the values for "onion-key-grace-period-days" is a
default value of 7 days, a minimum value of 1 day, and a maximum value
defined by other consensus parameter "onion-key-rotation-days" also
defined in days.

23ae5b655b Make MIN_ONION_KEY_LIFETIME a consensus parameter defined value.
This patch turns `MIN_ONION_KEY_LIFETIME` into a new function
`get_onion_key_lifetime()` which gets its value from a network consensus
parameter named "onion-key-rotation-days". This allows us to tune the
value at a later point in time with no code modifications.

We also bump the default onion key lifetime from 7 to 28 days as per
proposal #274.

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.

955d4b7abd circuit: Change close reasons from uint16_t to int
When marking for close a circuit, the reason value, a integer, was assigned to
a uint16_t converting any negative reasons (internal) to the wrong value. On
the HS side, this was causing the client to flag introduction points to be
unreachable as the internal reason was wrongfully converted to a positive
16bit value leading to flag 2 out of 3 intro points to be unreachable.

Fixes #20307 and partially fixes #21056

9192e5928c prop224 prepwork: Use of HS circuitmap in existing HS code.
The new HS circuitmap API replaces old public functions as follows:
   circuit_clear_rend_token -> hs_circuitmap_remove_circuit
   circuit_get_rendezvous -> hs_circuitmap_get_rend_circ
   circuit_get_intro_point -> hs_circuitmap_get_intro_circ_v2
   circuit_set_rendezvous_cookie -> hs_circuitmap_register_rend_circ
   circuit_set_intro_point_digest -> hs_circuitmap_register_intro_circ_v2

This commit also removes the old rendinfo code that is now unused.
It also fixes the broken rendinfo unittests.

2b9abbef2e prop224 prepwork: Introduce HS circuitmap subsystem.
The HS circuitmap is a hash table that maps introduction and rendezvous
tokens to specific circuits such that given a token it's easy to find
the corresponding circuit. It supports rend circuits and v2/v3 intro
circuits.

It will be used by the prop224 ESTABLISH_INTRO code to register and
lookup v3 introduction circuits.

The next commit after this removes the old code and fixes the unittests.
Please consult both commits while reviewing functionality differences
between the old and new code. Let me know if you want this rebased
differently :)

WRT architectural differences, this commit removes the rendinfo pointer
from or_circuit_t. It then adds an hs_token_t pointer and a hashtable
node for the HS circuitmap. IIUC, this adds another pointer to the
weight of or_circuit_t. Let me know if you don't like this, or if you
have suggestions on improving it.

55d02c004c Remove AuthDirMaxServersPerAuthAddr
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.

858c8f5593 Make new prop271 entry guards persistent
To do this, it makes sense to treat legacy guards as a separate
guard_selection_t *, and handle them separately.  This also means we
add support here for having multiple guard selections.

Note that we don't persist pathbias information yet; that will take
some refactoring.

dbbaa51518 Use the new guard notification/selection APIs throughout Tor
This patch doesn't cover every case; omitted cases are marked with
"XXXX prop271", as usual.  It leaves both the old interface and the
new interface for guard status notification, since they don't
actually work in the same way: the new API wants to be told when a
circuit has failed or succeeded, whereas the old API wants to know
when a channel has failed or succeeded.

I ran into some trouble with directory guard stuff, since when we
pick the directory guard, we don't actually have a circuit to
associate it with.  I solved that by allowing guard states to be
associated with directory connections, not just circuits.

238828c92b Add a new GUARD_WAIT state for circuits

dd6bdab3f6 Write the easy parts of the public entryguard interface.
Here we add a little bit of state to origin circuits, and set up
the necessary functions for the circuit code to call in order to
find guards, use guards, and decide when circuits can be used.

There's also an incomplete function for the hard part of the
circuit-maintenance code, where we figure out whether any waiting
guards are ready to become usable.

(This patch finally uses the handle.c code to make safe handles to
entry_guard_t objects, so that we are allowed to free an
entry_guard_t without checking whether any origin_circuit_t is
holding a reference to it.)

8293356ad9 hs: Refactor rend_data_t for multi version support
In order to implement proposal 224, we need the data structure rend_data_t to
be able to accomodate versionning that is the current version of hidden
service (2) and the new version (3) and future version.

For that, we implement a series of accessors and a downcast function to get
the v2 data structure. rend_data_t becomes a top level generic place holder.

The entire rend_data_t API has been moved to hs_common.{c|h} in order to
seperate code that is shared from between HS versions and unshared code (in
rendcommon.c).

This code stores the ed certs as appropriate, and tries to check

99b3e54691 Add "Ed ID" arguments to a bunch of connection-ID-related fns.
In particular, these functions are the ones that set the identity of
a given connection or channel, and/or confirm that we have learned
said IDs.

There's a lot of stub code here: we don't actually need to use the
new keys till we start looking up connections/channels by Ed25519
IDs.  Still, we want to start passing the Ed25519 IDs in now, so it
makes sense to add these stubs as part of 15055.
