670d402621 entrynodes: Make routine descriptor expiry notice logs less alarming
When tor is missing descriptors for some primary entry guards, make the
log message less alarming. It's normal for descriptors to expire, as long
as tor fetches new ones soon after.

Fixes bug 31657; bugfix on 0.3.3.1-alpha.

16a0b7ed67 guard: Ignore marked for close circuit when changing state to open
When we consider all circuits in "waiting for guard" state to be promoted to
an "open" state, we were considering all circuits, even the one marked for
close.

This ultiamtely triggers a "circuit_has_opened()" called on the circuit that
is marked for close which then leads to possible undesirable behaviors within
a subsystem.

For instance, the HS subsystem would be unable to find the authentication key
of the introduction point circuit leading to a BUG() warning and a duplicate
mark for close on the circuit.

This commit also adds a unit test to make sure we never select marked for
close circuits when upgrading its guard state from waiting for guard to open.

Fixes #30871

8015979eeb num_bridges_usable(): only count configured bridges.
When this function was implemented, it counted all the entry guards
in the bridge set.  But this included previously configured bridges,
as well as currently configured ones!  Instead, only count the
_filtered_ bridges (ones that are configured and possibly reachable)
as maybe usable.

Fixes bug 29875; bugfix on 0.3.0.1-alpha.

56738ff8c6 Add control port circuit ID to all pathbias bug messages.

and obtain control port logs (or use any other control port CIRC and
CIRC_MINOR event logging mechanism).

b98bcd789e Pathbias should continue to ignore previously ignored circs.
If circuit padding wants to keep a circuit open and pathbias used to ignore
it, pathbias should continue to ignore it.

This may catch other purpose-change related miscounts (such as timeout
measurement, cannibalization, onion service circuit transitions, and
vanguards).

aa360b255b Fix crash bug in PT subsystem.
This patch fixes a crash bug (assertion failure) in the PT subsystem
that could get triggered if the user cancels bootstrap via the UI in
TorBrowser. This would cause Tor to call `managed_proxy_destroy()` which
called `process_free()` after it had called `process_terminate()`. This
leads to a crash when the various process callbacks returns with data
after the `process_t` have been freed using `process_free()`.

We solve this issue by ensuring that everywhere we call
`process_terminate()` we make sure to detach the `managed_proxy_t` from
the `process_t` (by calling `process_set_data(process, NULL)`) and avoid
calling `process_free()` at all in the transports code. Instead we just
call `process_terminate()` and let the process exit callback in
`managed_proxy_exit_callback()` handle the `process_free()` call by
returning true to the process subsystem.

4efe4cc2f9 Add support for STATUS messages from Pluggable Transports.
This patch adds support for the new STATUS message that PT's can emit

This patch changes the LOG pluggable transport message to use the recent

severity level as well as the message. A mapping between the PT log
severity levels and Tor's log serverity level is provided.

ec2ae3ed8b Change EVENT_TRANSPORT_LOG to EVENT_PT_LOG.
This patch changes our EVENT_TRANSPORT_LOG event to be EVENT_PT_LOG. The
new message includes the path to the PT executable instead of the
transport name, since one PT binary can include multiple transport they
sometimes might need to log messages that are not specific to a given
transport.

e3ceaebba2 Add support for logging messages from pluggable transports.
This patch adds support for the "LOG" protocol message from a pluggable
transport. This allows pluggable transport developers to relay log
messages from their binary to Tor, which will both emit them as log
messages from the Tor process itself, but also pass them on via the
control port.

bfb94dd2ca Use process_t for managed proxies.
