Existing cached directory information can cause misleadingly high
bootstrap percentages. To improve user experience, defer reporting of
directory information progress until at least one connection has
succeeded to a relay or bridge.
Closes ticket 27169.
Track bootstrap phase (enumerated by bootstrap_status_t) independently
from the bootstrap progress (which can represent intermediate
progress). This allows control_event_bootstrap_problem() to avoid
doing a linear search through the bootstrap progress space to find the
current bootstrap phase.
Move the mostly-invariant part of control_event_boostrap() into a
helper control_event_bootstrap_core(). The helper doesn't modify any
state beyond doing logging and control port notifications.
Simplify control_event_bootstrap() by making it return void again. It
is currently a fairly complicated function, and it's made more
complicated by returning an int to signal whether it logged at NOTICE
or INFO.
The callers conditionally log messages at level NOTICE based on this
return value. Change the callers to unconditionally log their verbose
human-readable messages at level INFO to keep NOTICE logs less
cluttered.
This partially reverts the changes of #14950.
One HSv3 unit test used "tor_memeq()" without checking the return value. This
commit changes that to use "tt_mem_op()" to actually make the test validate
something :).

This is an attempt to work around what I think may be a bug in
OSS-Fuzz, which thinks that uninitialized data might be passed to
the curve25519 functions.
