This patch makes sure we lowercase the value of BridgeDistribution
before we add it to the descriptor as `bridge-distribution-request`.
See: https://bugs.torproject.org/32753
This patch makes sure that we accept values such as "nOne", "None", and
"AnY" as valid values for BridgeDistribution. We later ensure to
lower-case the values before they are forwarded to the BridgeDB.
See: https://bugs.torproject.org/32753
When the BridgeDistribution value was added in commit
ebab521525 the check for whether the value
contains '\n' or '\r' was added as a requirement for whether or not the
value should be escaped.
This patch removes this check and makes sure we call `escaped()` on the
value every time before we add it to a descriptor.

We hit this assertion with bug 32868, but I'm stymied figuring out
how we wound up with a routerstatus like this. This patch is a
diagnostic to attempt to figure out what is going on, and to avoid a
crash in the meantime.
When looking up an entry in the rend_cache, stop asserting that it exists but
rather confirm it exists and if not, return that no entry was found.
The reason for that is because the hs_circ_cleanup_on_free() function (which
can end up looking at the rend_cache) can be called from the
circuit_free_all() function that is called _after_ the rend cache is cleaned
up in tor_free_all().
We could fix the free all ordering but then it will just hide a future bug.
Instead, handle a missing rend_cache as a valid use case as in while we are in
the cleanup process.
As Tor becomes more modular, it is getting more and more difficult to ensure
subsystem callstack ordering thus this fix aims at making the HSv2 subsystem
more robust at being called while tor is pretty much in any kind of state.
Fixes#32847.

Some ".c" files define *_PRIVATE macros, but those macros are
not used in any header file. Delete them.
These changes were created using the "make autostyle" from
32522, and then split into commits.
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.
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.
