The signed_descriptor_move() was not releasing memory inside the destination
object before overwriting it with the source object. This commit adds a reset
function that free that memory inside a signed descriptor object and zero it.
Closes#20715.

Tor 0.2.9 has a broader range of fixes and workarounds here, but for
0.2.8, we're just going to maintain the existing behavior.
(The alternative would be to backport both
1eba088054 and
16fcbd21c9 , but the latter is kind of
a subtle kludge in the configure.ac script, and I'm not a fan of
backporting that kind of thing.)
(OpenSSL 1.1 makes EVP_CIPHER_CTX opaque, _and_ adds acceleration
for counter mode on more architectures. So it won't work if we try
the older approach, and it might help if we try the newer one.)
Fixes bug 20588.
When computing old Tor protocol line version in protover, we were looking at
0.2.7.5 twice instead of the specific case for 0.2.9.1-alpha.

newconn->address is strdup'ed twice when new_type == CONN_TYPE_AP
and conn->socket_family == AF_UNIX. Whilst here, juggle code to
make sure newconn->port is assigned from an initialised value in
the above case.
Instead, refuse to start tor if any hidden service key has been used in
a different hidden service anonymity mode.
Fixes bug 20638; bugfix on 17178 in 0.2.9.3-alpha; reported by ahf.
The original single onion service poisoning code checked poisoning state
in options_validate, and poisoned in options_act. This was problematic,
because the global array of hidden services had not been populated in
options_validate (and there were ordrering issues with hidden service
directory creation).
This patch fixes this issue in rend_service_check_dir_and_add, which:
* creates the directory, or checks permissions on an existing directory, then
* checks the poisoning state of the directory, then
* poisons the directory.
When validating, only the permissions checks and the poisoning state checks
are perfomed (the directory is not modified).
Apple is supposed to decorate their function declarations with
macros to indicate which OSX version introduced them, so that you
can tell the compiler that you want to build against certain
versions of OSX. But they forgot to do that for clock_gettime() and
getentropy(), both of which they introduced in 10.12.
This patch adds a kludge to the configure.ac script where, if we
detect that we are targeting OSX 10.11 or earlier, we don't even probe
to see if the two offending functions are present.
Closes ticket 20235.
For relays that don't know their own address, avoid attempting
a local hostname resolve for each descriptor we download. Also cut
down on the number of "Success: chose address 'x.x.x.x'" log lines.
Fixes bugs 20423 and 20610; bugfix on 0.2.8.1-alpha.
