This test doesn't set PYTHON, and ignores USE_PYTHON. And it's already
listed in TEST_SCRIPTS.

Except for src/ext, which we may not want to modify.

With v3, the "pending_final_cpath" of a circuit is always NULL which means
that for v3, established client rendezvous circuit waiting for the intro point
to ACK, will always end up timing out quickly.

This can increase the delays to which you connect to a service since in order
to succeed, the rendezvous circuit needs to fully established
(CIRCUIT_PURPOSE_C_REND_JOINED) within the cutoff of the introduction circuit
as well which is these days around 2-3 seconds.

Fixes #32021

Simplify handle_control_getinfo() by using the new reply lines
abstraction.  Previously, this function explicitly checked for whether
it should generate a MidReplyLine, a DataReplyLine, or an
EndReplyLine.  control_write_reply_lines() now abstracts this check.

Simplify handle_control_protocolinfo() by using the new reply line
abstraction.

Factor out the parts of handle_control_protocolinfo() that assemble
the AUTHMETHODS and COOKIEFILE strings.

In handle_control_getconf(), use the new control reply line
abstraction to simplify output generation.  Previously, this function
explicitly checked for whether it should generate a MidReplyLine or an
EndReplyLine.  control_write_reply_lines() now abstracts this check.

Add the KV_RAW flag to kvline_encode().  This allows generation of
output that is compatible with some quirks of the control protocol.

Add a check for '=' characters in needs_escape().  This simplifies the
logic in kvline_can_encode_lines().
