Drive a loopback daemon (secure stdio-pipe transport by default, also green
under --use-tcp) via the new write_daemon_conf helper and assert the behaviour
of the security-relevant rsyncd.conf parameters, transferring >=3-deep trees:
daemon-access path / read only / write only / list, incl. a deep sub-path
pull and that a list=no module is hidden yet usable by name.
daemon-filter daemon exclude hides matching files everywhere; incoming /
outgoing chmod rewrite modes of every transferred file.
daemon-auth auth users + secrets file accept the right password, reject a
wrong one and an unauthenticated request; strict modes rejects
a world-readable secrets file.
daemon-exec pre-/post-xfer exec run with RSYNC_MODULE_NAME /
RSYNC_EXIT_STATUS; a failing pre-xfer exec aborts the transfer
(marker files polled for, since post-xfer exec runs after the
client disconnects under TCP).
daemon-munge munge symlinks stores incoming links with the /rsyncd-munged/
prefix and strips it on the way out.
daemon-refuse refuse options: a named option, a wildcard, and the '* !a !v'
allow-list idiom.
Green on master under pipe and --use-tcp transports and under --protocol=29.
