It is possible that tor was compiled with KIST support but the running kernel
has no support for it. In that case, fallback to a naive approach and flag
that we have no kernel support.
At this commit, if the kernel support is disabled, there are no ways to come
back from it other than restarting tor with a kernel that supporst KIST.

Add a detection for the KIST scheduler in our build system and set
HAVE_KIST_SUPPORT if available.
Adapt the should use kist function with this new compile option.

- HT_FOREACH_FN defined in an additional place because nickm did that
in an old kist prototype
- Make channel_more_to_flush mockable for future sched tests
- Add empty scheduler_{vanilla,kist}.c files and put in include.am

- massive change to src/tgest/test_options.c since the sched options
were added all over the place in it
- removing the sched options caused some tests to pass/fail in new ways
so I assumed current behavior is correct and made them pass again
- ex: "ConnLimit must be greater" lines
- ex: "Authoritative directory servers must" line
- remove test_options_validate__scheduler in prep for new sched tests

Version 3 hidden service needs rendezvous point that have the protocol version
HSRend >= 2 else the rendezvous cells are rejected.

There are two reasons this is likeliest to happen -- no kernel
support, and some bug in Tor. We'll ask people to check the former
before they report. Closes 23090.
I'm doing this using the Proxy-Authorization: header to support
clients that understand it, and with a new tor-specific header that
makes more sense for our use.
By convention, a function that frobs a foo_t should be called
foo_frob, and it should have a foo_t * as its first argument. But
for many of the buf_t functions, the buf_t was the final argument,
which is silly.
Our convention is that functions which manipulate a type T should be
named T_foo. But the buffer functions were super old, and followed
all kinds of conventions. Now they're uniform.
Here's the perl I used to do this:
\#!/usr/bin/perl -w -i -p
s/read_to_buf\(/buf_read_from_socket\(/;
s/flush_buf\(/buf_flush_to_socket\(/;
s/read_to_buf_tls\(/buf_read_from_tls\(/;
s/flush_buf_tls\(/buf_flush_to_tls\(/;
s/write_to_buf\(/buf_add\(/;
s/write_to_buf_compress\(/buf_add_compress\(/;
s/move_buf_to_buf\(/buf_move_to_buf\(/;
s/peek_from_buf\(/buf_peek\(/;
s/fetch_from_buf\(/buf_get_bytes\(/;
s/fetch_from_buf_line\(/buf_get_line\(/;
s/fetch_from_buf_line\(/buf_get_line\(/;
s/buf_remove_from_front\(/buf_drain\(/;
s/peek_buf_startswith\(/buf_peek_startswith\(/;
s/assert_buf_ok\(/buf_assert_ok\(/;
This lets us drop the testing-only function buf_get_first_chunk_data(),
and lets us implement proto_http and proto_socks without looking at
buf_t internals.
The service needs the latest SRV and set of relays for the best accurate
hashring to upload its descriptor to so it needs a live consensus thus don't
do anything until we have it.
