This patch adds support for Android's logging subsystem in Tor. When
debugging Android applications it is useful to be able to collect
information about the application running on the platform via the
various system services that is available on the platform.
This patch allows you to add "Log notice android" to your torrc and have
Tor send everything above and including the notice severity to Android's
ring buffer which can be inspected using the 'adb logcat' program.

This patch ensures that we more easily can extend our log backends that
does not take any additional argument other than a single keyword. This
patch is mostly reindentation of some code which is why it is split out
into its own patch.

Also make IPv6-only clients wait for microdescs for relays, even if we were
previously using descriptors (or were using them as a bridge) and have
a cached descriptor for them.
But if node_is_a_configured_bridge(), stop waiting for its IPv6 address in
a microdescriptor, because we'll never use it.
Implements #23827.
networkstatus_consensus_has_ipv6() tells us whether the consensus method of
our current consensus supports IPv6 ORPorts in the consensus.
Part of #23827.
This commit was made mechanically by this perl script:
\#!/usr/bin/perl -w -i -p
next if /^#define FREE_AND_NULL/;
s/\bFREE_AND_NULL\((\w+),/FREE_AND_NULL\(${1}_t, ${1}_free_,/;
s/\bFREE_AND_NULL_UNMATCHED\(/FREE_AND_NULL\(/;
This commit removes the old FREE_AND_NULL, and renames the old
FREE_AND_NULL_UNMATCHED so that it is now called FREE_AND_NULL.
This will break all the FREE_AND_NULL_* users; the next commit will
fix them.
Couple things happen in this commit. First, we do not re-queue a cell back in
the circuit queue if the write packed cell failed. Currently, it is close to
impossible to have it failed but just in case, the channel is mark as closed
and we move on.
The second thing is that the channel_write_packed_cell() always took ownership
of the cell whatever the outcome. This means, on success or failure, it needs
to free it.
It turns out that that we were using the wrong free function in one case and
not freeing it in an other possible code path. So, this commit makes sure we
only free it in one place that is at the very end of
channel_write_packed_cell() which is the top layer of the channel abstraction.
This makes also channel_tls_write_packed_cell_method() return a negative value
on error.
Two unit tests had to be fixed (quite trivial) due to a double free of the
packed cell in the test since now we do free it in all cases correctly.

Split hs_circuitmap_get_rend_circ_client_side(). One returns only established
circuits (hs_circuitmap_get_established_rend_circ_client_side()) and the other
returns all kinds of circuits.
