691d271b2e Re-order thread initialization to follow logging, and remove a comment. 
lib/log no longer uses lib/thread; lib/log only uses lib/lock, which
is at a lower level.

Lowercase the BridgeDistribution value from torrc in descriptors. 
This patch ensures that we always lowercase the BridgeDistribution from
torrc in descriptors before submitting it.

99a5aecbc7 Wrap columnar tables in "clang-format off/on" 
These tables have aligned comments, so we don't want clang-format to

06a6130666 Use parentheses to avoid mis-indentations of stringified macro args 
clang-format sometimes thinks that "#name" should be written as
"#     name" if it appears at the start of a line.  Using () appears
to suppress this, while confusing Coccinelle.

config: Make clients tell dual-stack exits they prefer IPv6 
Make Tor clients tell dual-stack exits that they prefer IPv6
connections.

This change is equivalent to setting the PreferIPv6 flag on
SOCKSPorts (and most other listener ports). Tor Browser has
been setting this flag for some time, and we want to remove a
client distinguisher at exits.

Also update the man page, putting all the IP flags in their
non-default forms.

Closes ticket 32637.

42e31b5c45 Mark TestingEstimatedDescriptorPropagationTime as obsolete. 
We stopped looking at this option in 85cf6dcba3, back when we
implemented the minimal pieces of prop275.  Since then, we've had
code to validate and adjust this option, and to give it a different
value in testing networks, but the option hasn't actually done
anything.

We can safely mark it as OBSOLETE, since doing so does not make any
old configuration get rejected.

ext, test, and trunnel.

cd src
for dname in $(find lib core feature app tools -type d |grep -v \\.deps$); do
    keyword="$(echo "$dname" |sed -e "s/\//_/" )"
    target="${dname}/${keyword}.dox"
    echo "$target"
    cat <<EOF >"$target"
/**
@dir ${dname}
@brief ${dname}
**/
EOF

    git add "$target"
