Instead of replacing connection_t.{addr,port} with a canonical
orport, and tracking the truth in real_addr, we now leave
connection_t.addr alone, and put the canonical address in
canonical_orport.

This fixes CID 1465291, which was a complaint that we never actually
checked the return value of this function. It turns out that this
function was failing, and it didn't matter, because it wasn't
necessary for this test.
This is an automated commit made with a python script.
After running the automated script, I had to hand-revert the cases where it
made the conversion functions call themselves.
Additionally, I had to edit a variable declaration in control_bootstrap.c so
that the result of a const cast could be put in a const field.
Create a doc/tracing/ directory to contain a top level README.md which is the
previously named Tracing.md and add the EventsCircuit.md which describes the
circuit subsystem tracing events in depth.

Only log the 'real_addr' when it is set to something.
Only log the ID when it is set.
When scrubbing the address, don't include a canonical address.
(There should never be a canonical address for a connection with no
ID set.)
Now that we've clarified that these functions only need to describe
the peer in a human-readable way, we can have them delegate to
connection_describe_peer().
This mode was only used in one place, and it caused a dangerous
mingling of functionality. The method is supposed to _describe_ the
peer's address, not give its actual address. We already had a
function to get the actual address.
* We no longer call this an optional method
* We document that it returns the real address, not a canonical one.
* We have it try harder if the real address hasn't been set yet.
This patch ensures that we strip "\r" characters on both Windows as well
as Unix when we read text files. This should prevent the issue where
some Tor state files have been moved from a Windows machine, and thus
contains CRLF line ending, to a Unix machine where only \n is needed.
We add a test-case to ensure that we handle this properly on all our
platforms.

Pass the IPv4 before the IPv6 like all our other interfaces.

This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.
Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.
The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".
This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.

Remove all the escape character "\" which is not needed for Markdown files.
This also fixes the tracing event include to the correct path.

These fields have a complicated history, some slightly complicated
behavior, and some definitely inadequate documentation. Before we
go fixing them up, let's document how they work now.
check-cocci is still a good idea -- perhaps as a cron job? But
doing it as part of our regular tests has just been confusing,
especially to volunteers who shouldn't have to become coccinelle
experts in order to get their patches through our CI.
Closes#40030.
