When closing parallel introduction points, the given reason (timeout)
was actually changed to "no reason" thus when the circuit purpose was
CIRCUIT_PURPOSE_C_INTRODUCE_ACK_WAIT, we were reporting an introduction
point failure and flagging it "unreachable". After three times, that
intro point gets removed from the rend cache object.
In the case of CIRCUIT_PURPOSE_C_INTRODUCING, the intro point was
flagged has "timed out" and thus not used until the connection to the HS
is closed where that flag gets reset.
This commit adds an internal circuit reason called
END_CIRC_REASON_IP_NOW_REDUNDANT which tells the closing circuit
mechanism to not report any intro point failure.
This has been observed while opening hundreds of connections to an HS on
different circuit for each connection. This fix makes this use case to
work like a charm.
Fixes#13698.

Instead, generate new keys, and overwrite the empty key files.
Adds FN_EMPTY to file_status_t and file_status.
Fixes bug 13111.
Related changes due to review of FN_FILE usage:
Stop generating a fresh .old RSA key file when the .old file is missing.
Avoid overwriting .old key files with empty key files.
Skip loading zero-length extra info store, router store, stats, state,
and key files.
Stop crashing when a NULL filename is passed to file_status(),
instead, return FN_ERROR.
Also return FN_ERROR when a zero-length filename is passed to file_status().
Fixed as part of bug 13111.
This is meant to prevent memory corruption bugs from doing
unspeakable infinite-loop-like things to the hashtables. Addresses
ticket 11737. We should disable these if they turn out to be
expensive.
Authorities are no longer voting on Named, so specifying nodes by
nickname isn't a clever thing to do. (Not that it ever was!) So
remove the documentation that suggests that you should do it.
Additionally, add proper cross-references to our __node__ lists, and
explain about the optional $ before identity digests.
Also, the oxford comma: endorsed by Steven Pinker, my spouse, and my
11th grade English teacher.
Closes 13381.
