See #14881

The tor_fragile_assert() bug has existed here since c8a5e2d5
in tor-0.2.1.7-alpha forever, but tor_fragile_assert() was mostly a
no-op until 0.2.9.1-alpha.

Fixes bug 19869.

When we refactored purpose_needs_anonymity(), we made it so _all_
bridge requests required anonymity.  But that missed the case
that we are allowed to ask a bridge for its own descriptor.

With this patch, we consider the resource, and allow "authority.z"
("your own descriptor, compressed") for a bridge's server descriptor
to be non-anonymous.

Fix for bug 20410; bug not in any released Tor.

Closes #20435

I believe that this should never trigger, but if it does, it
suggests that there was a gap between is_sensitive_dir_purpose and
purpose_needs_anonymity that we need to fill.  Related to 20077.

Conflict in entrynodes.c: any_bridge_supports_microdescriptors was
removed in master, and modified in 19858_v2
