620e40bcfc test_options: add a test for options_trial_assign()
This function is used by controllers to set options.  I refactored
it a bit when refactoring options validation, so it needs to get
tested.

06475f30e9 tests: set DataDirectory_option as well as DataDirectory.
options_validate_cb() derives DataDirectory (which we use) from
DataDirectory_option (which the user sets).  I want to add a test
that will call options_validate_cb(), but it will fail unless it
derives the same value.

e0ae137df5 Write a new set of config validation callbacks.
Unlike legacy_validate_fn_t, these callbacks have separation of
duties, into:

    * early normalization and computation.
    * validation
    * transition checking
    * late normalization and computation

Only the first and last steps get mutable objects.  Only the
transition-checking step gets to see the previous values of this
object.

dc6d7f072d Make foo_validate() functions call config_validate().
The former foo_validate() functions are now toplevel
legacy_validate_fn callbacks.  The new foo_validate() functions now
call them.

This change lets us remove the old shared_random disk state
validation callback entirely.

0cb4238537 Add a config_validate() function to invoke verify callbacks.
As we turn our monolithic configuration objects into suites of
smaller module-specific configuration objects, we will want each one
to be able to provide its own verification callbacks.  That means
that instead of invoking these verification callbacks directly, we will
want to call them via the configuration manager object.

4a248bafba Rename validate_fn{,_t} to start with "legacy_".
The current API of this callback mixes responsibilities, including:
  * validation
  * transition checking
  * processing (modifying) the configuration object.

These will have to be disentangled piece by piece, so for now, we'll
have "legacy" validate functions as well.

7c0f966668 test_options: don't pass an old_options argument to options_validate()
This input was inessential, and none of the tests actually depended
on it or tested anything about it (as can be seen from the fact that
tests all still pass when it's removed).

I tried to generate this commit with a coccinelle script, but it had
trouble parsing a lot of options_validate as it stands.  Instead, I
did a search-and-replace to replace "tdata->old_opt," with "NULL,".

09468cc58b dir: Look if circuit is closed in connection_dir_is_anonymous()

ed57a04a65 hs-v3: Remove a BUG() caused by an acceptable race
hs_client_purge_state() and hs_cache_clean_as_client() can remove a descriptor
from the client cache with a NEWNYM or simply when the descriptor expires.

Which means that for an INTRO circuit being established during that time, once
it opens, we lookup the descriptor to get the IP object but hey surprised, no
more descriptor.

The approach here is minimalist that is accept the race and close the circuit
since we can not continue. Before that, the circuit would stay opened and the
client wait the SockTimeout.

Fixers #28970.

b6c24eb484 hs-v3: Remove the circuit_established intro flag
Only use the HS circuit map to know if an introduction circuit is established
or not. No need for a flag to keep state of something we already have in the
circuit map. Furthermore, the circuit map gets cleaned up properly so it will
always have the "latest truth".

This commit also removes a unit test that was testing specifically that flag
but now we rely solely on the HS circuit map which is also tested few lines
below the removed test.

98c3b3bb4c Update tests to handle new interpretation of quiet_level.
Two things needed to be changed.  First, we used to set quiet_level
to the default (QUIET_NONE) when running tests, since we would not
call anything that acted based upon it.  But since we sometimes call
options_init_logs(), we need to pre-set quiet_level to QUIET_SILENT
in the logs so that we don't add the default logs.  This did not
cause test failure: just unwanted logs.

Second, we had a test that checked whether options_validate was
messing with options->Logs correctly.  Since options_validate no
longer messes with the logs, we no longer want a test for this.

e07b19d305 Rationalize handling of quiet_level in config.c
Formerly, we would use quiet_level as an excuse to rewrite the log
configuration, adding a default log line if none existed, and if
RunAsDaemon was not set, and if we were not being invoked via
setconf (!).

This is against our best practices for several reasons:
  * We should not be changing configured options except when the
    user tells us to do so.
  * We should especially not be changing options in the options_validate
    function.
  * Distinguishing whether we are being called from setconf adds a
    risky special-case.

Instead, this patch take a simpler approach: it changes the
interpretation of having no logging lines set to mean: If there is a
stdout, add a default log based on quiet_level.

Solves ticket 31999.

a10e4d737e test_options: use testing options with (almost) real defaults.

pretty severe workarounds throughout the code, as our options fail
to validate, or count as "default" for the wrong reasons.

Note that in some places, we stop getting spurious warnings or
failures which the tests previously demanded.  In these cases, I've
changed the test behavior.

a7ccd9a997 respect accountingmax during soft hibernation
Relays now respect their AccountingMax bandwidth again. When relays
entered "soft" hibernation (which typically starts when we've hit
90% of our AccountingMax), we had stopped checking whether we should
enter hard hibernation. Soft hibernation refuses new connections and
new circuits, but the existing circuits can continue, meaning that
relays could have exceeded their configured AccountingMax.

This commit rolls back some of the cpu-saving fixes, where we tried
to avoid calling so many of our events while we're off the network.

That's because PERIODIC_EVENT_FLAG_NEED_NET checks net_is_disabled(),
which returns true even if we're only in soft hibernation.

Fixes bug 32108; bugfix on 0.4.0.1-alpha.
