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.

408c53b7a7 Scale IPv6 address counts in policy_summary_reject to avoid overflow
This disregards anything smaller than an IPv6 /64, and rejects ports that
are rejected on an IPv6 /16 or larger.

Adjust existing unit tests, and add more to cover exceptional cases.

No IPv4 behaviour changes.

4667a40ca9 Fix IPv6 support in policy_summary_reject and policy_summary_accept
This interim fix results in too many IPv6 rejections.

No behaviour change for IPv4 counts, except for overflow fixes that
would require 4 billion redundant 0.0.0.0/0 policy entries to trigger.

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.

d183ec231b Call monotime_init() earlier.
We need to call it before nt_service_parse_options(), since
nt_service_parse_options() can call back into nt_service_main(),

746d959100 Don't build circuits till primary guards have descriptors
In addition to not wanting to build circuits until we can see most
of the paths in the network, and in addition to not wanting to build
circuits until we have a consensus ... we shouldn't build circuits
till all of our (in-use) primary guards have descriptors that we can
use for them.

This is another bug 21242 fix.

02da24f8e5 Don't (usually) return any guards that are missing descriptors.
Actually, it's _fine_ to use a descriptorless guard for fetching
directory info -- we just shouldn't use it when building circuits.
Fortunately, we already have a "usage" flag that we can use here.

Partial fix for bug 21242.

26957a127a entry_guard_pick_for_circuit(): TRAFFIC guards must have descriptors
This relates to the 21242 fix -- entry_guard_pick_for_circuit()
should never yield nodes without descriptors when the node is going
to be used for traffic, since we won't be able to extend through
them.

93b39c5162 Downgrade assertion to nonfatal for #21242
This assertion triggered in the (error) case where we got a result
from guards_choose_guard() without a descriptor.  That's not
supposed to be possible, but it's not worth crashing over.

4d83999213 Make "GETCONF SocksPort" work again
I broke "GETCONF *Port" in 20956, when I made SocksPort a
subordinate option of the virtual option SocksPortLines, so that I
could make SocksPort and __SocksPort provide qthe same
functionality.  The problem was that you can't pass a subordinate
option to GETCONF.

So, this patch fixes that by letting you fetch subordinate options.

It won't always be meaningful to consider these options
out-of-context, but that can be the controller-user's
responsibility to check.

Closes ticket 21300.

96c7ddbc7e 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.
