Fixes #23910

Based on a patch by dgoulet; backported to 0.2.5

When we added single_conn_free_bytes(), we cleared the outbuf on a
connection without setting outbuf_flushlen() to 0.  This could cause
an assertion failure later on in flush_buf().

Fixes bug 23690; bugfix on 0.2.6.1-alpha.

Authority IPv6 addresses were originally added in 0.2.8.1-alpha.

This leaves 3/8 directory authorities with IPv6 addresses, but there
are also 52 fallback directory mirrors with IPv6 addresses.

Resolves 19760.

Fixes bug 23490; bugfix on 0.2.7.2-alpha.
