In KIST, we could have a small congestion window value than the unacked
packets leading to a integer overflow which leaves the tcp_space value to be
humongous.
This has no security implications but it results in KIST scheduler allowing to
send cells on a potentially saturated connection.
Found by #24423. Fixes#24590.

This function leaks memory when the event_base is freed before the
event itself fires. That's not harmful, but it's annoying when
trying to debug other memory leaks.
Fixes bug 24584; bugfix on 0.2.8.1-alpha.
When we didn't do this before, we'd have some still-reachable memory
warnings, and we'd find ourselves crashing when we tried to
reinitialize libevent.

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.

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.
