ffa3499d81 Add config object for dirauth; move one option there.
I've chosen the "AuthDirMaxServersPerAddr" option here for
simplicity, since it is used literally nowhere else besides the dirauth
module.  Once we have all the infrastructure in place for this, we
can move more options into this structure.

5e2318165d Add "stub" files for disabled modules.
These modules are only built when the selected modules are disabled.
The provide stub implementations of the subsystem blocks.  Later,
other stub implementations could move here.

Having real subsystem blocks here will let us handle disabled
configuration options better.

9ad569c71d practracker: Add missing .may_include files
All of these files contain "*.h", except for:
* src/app/config/.may_include
* src/test/.may_include
which also contain "*.inc".

This change prevents includes of "*.c" files, and other
unusually named files.

a30d143228 Make KeyDirectory's GroupReadable behave the same as CacheDirectory's.
In #26913 we solved a bug where CacheDirectoryGroupReadable would
override DataDirectoryGroupReadable when the two directories are the
same.  We never did the same for KeyDirectory, though, because
that's a rare setting.

Now that I'm testing this code, though, fixing this issue seems
fine.  Fixes bug #27992; bugfix on 0.3.3.1-alpha.

15371d801c Mark more torrc options as FILENAME rather than as STRING.

FILENAME options currently are the same as STRINGs in most respects,
except for the type reported to the controller.

In this commit, I'm picking the options to change based on:
  * the current contents of warn_about_relative_paths()
  * options that end with "File".

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

validation callback entirely.

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.

This is an automated commit, generated by this command:

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.

3a73f6612a Replace add_temp_log() with add_default_log().
We used to have this function so that we could mark our initial
log-to-stdout as specifically temporary so that we would delete it
once regular logs were configured.  But it's no longer necessary to
mark these logs as temporary, since we now use a mark-and-sweep
process to ensure that _all_ not-configured logs are closed when we
change our configuration.

Instead, this function will be the basis of a refactoring in how we
handle default logs.

47654d3249 Refactor config free logic to use a single path.
The right way to free a config object is now to wrap config_free(),
always.  Instead of creating an alternative free function, objects
should provide an alternative clear callback to free any fields that
the configuration manager doesn't manage.

This lets us simplify our code a little, and lets us extend the
confparse.c code to manage additional fields in config_free.

3d1f9f583a Use special magic to enforce manager/object connection.
Every time we finalize a config manager, we now generate a new magic
number for it, so that we'll get an assertion failure if we ever try
to use an object with a different configuration manager than the one
that generated it.

This C file will eventually belong in lib/confmgt, so it needs to

routerset.c, we can adjust its includes accordingly.

I'm not moving the file yet, since it would make fixup commits on
earlier branches here really hard to do.

dde091ebc7 Add a "freeze" function for config_mgr_t objects.
It's important to make sure that we don't change a config_mgr_t
after we start using it to make objects, or we could get into
inconsistent states.  This feature is the start of a safety
mechanism to prevent this problem.

f306d12b58 Refactor handling of TestingTorNetwork
Previously, when TestingTorNetwork was set, we would manually adjust
the initvalue members of a bunch of other config_var_t, and then
re-run the early parts or parsing the options.

Now we treat the initvalue fields as immutable, but instead assign
to them in options_init(), as early as possible.  Rather than
re-running the early parts of options, we just re-call the
options_init_from_string() function.

This patch de-kludges some of our code pretty handily.  I think it
could later handle authorities and fallbacks, but for now I think we
should leave those alone.

769fe81717 Start teaching config_mgr_t to handle sub-objects and sub-formats
The eventual design here will be that multiple config_format_t
objects get registered with a single config_mgr_t.  That
config_mgr_t manages a "top-level" object, which has a pointer to
the other objects.

I had earlier thought of a different design, where there would be no
top-level object, and config_mgr_t would deal with a container
instead.  But this would require a bunch of invasive refactoring
that I don't think we should do just yet.

e8dc513bd0 Add a config_mgr_t type to wrap config_format_t
Remember that our goal in the present refactoring is to allow each
subsystem to declare its own configuration structure and
variables.  To do this, each module will get its own
config_format_t, and so we'll want a different structure that wraps
several config_format_t objects.  This is a "config_mgr_t".

a7835202cf Turn several properties of types or variables into flags.
"unsettable" is a property of types.  LINELIST_V and OBSOLETE are
unsettable, meaning that they cannot be set by name.

"contained" is a property of types.  I'm hoping to find a better
name here.  LINELIST_S is "contained" because it always appears
within a LINELIST_V, and as such doesn't need to be dumped ore
copied independently.

"cumulative" is a property of types. Cumulative types can appear
more than once in a torrc without causing a warning, because they
add to each other rather than replacing each other.

"obsolete" is a property of variables.

"marking fragile" is now a command that struct members can accept.

With these changes, confparse and config no longer ever need to
mention CONFIG_TYPE_XYZ values by name.

in a safer API as we do #30914 and lower the struct manipulation
code as well.
