The current API of this callback mixes responsibilities, including:

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.

Only use the HS circuit map to know if an introduction circuit is established

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.

This patch removes an overly strict tor_assert() and an ignorable BUG()

d91ad5112e Check tor_vasprintf for error return values.
In case of error, a negative value will be returned or NULL written into
first supplied argument.

This patch uses both cases to comply with style in the specific files.

A tor_vasprintf error in process_vprintf would lead to a NULL dereference
later on in buf_add, because the return value -1 casted to size_t would
pass an assertion check inside of buf_add.

On the other hand, common systems will fail on such an operation, so it
is not a huge difference to a simple assertion. Yet it is better to
properly fail instead of relying on such behaviour on all systems.
