Users can't run an anonymous client and non-anonymous single
onion service at the same time. We need to know whether we have
any client ports or sockets open to do this check.
When determining whether a client port (SOCKS, Trans, NATD, DNS)
is set, count unix sockets when counting client listeners. This
has no user-visible behaviour change, because these options are
set once and never read in the current tor codebase.
Don't count sockets when setting ControlPort_set, that's what
ControlSocket is for. (This will be reviewed in #19665.)
Don't count sockets when counting server listeners, because the code
that uses these options expects to count externally-visible ports.
(And it would change the behaviour of Tor.)
Copying the integer 42 in a char buffer has a different representation
depending on the endianess of the system thus that unit test was failing on
big endian system.
This commit introduces a python script, like the one we have for SRV, that
computes a COMMIT/REVEAL from scratch so we can use it as a test vector for
our encoding unit tests.
With this, we use a random value of bytes instead of a number fixing the
endianess issue and making the whole test case more solid with an external
tool that builds the COMMIT and REVEAL according to the spec.

Rely on onion_populate_cpath to check that we're only using
TAP for the rare hidden service cases.
Check and log if handshakes only support TAP when they should support
ntor.
This bug had existed since 0.2.4.7-alpha, but now that we have
FallbackDirs by default, it actually matters.
Fixes bug 19947; bugfix on 0.2.4.7-alpha or maybe 0.2.8.1-alpha.
Rubiate wrote the patch; teor wrote the changes file.
OpenBSD removes this function, and now that Tor requires Libevent 2,
we should also support the OpenBSD Libevent 2.
Fixes bug 19904; bugfix on 0.2.5.4-alpha.
