This resolves two issues:
* the checks in rend_add_services were only being performed when adding
the service, and not when the service was validated,
(this meant that duplicate checks were not being performed, and some SETCONF
commands appeared to succeed when they actually failed), and
* if one service failed while services were being added, then the service
list would be left in an inconsistent state (tor dies when this happens,
but the code is cleaner now).
Fixes#20860.
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.

Coverity doesn't like it when there are paths to the end of the
function where something doesn't get freed, even when those paths
are only reachable on unit test failure.
Fixes CID 1372899 and CID 1372900. Bug not in any released Tor.
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 until the misconfigurations have been corrected.
Fixes bug 20559; bugfix on multiple commits in 0.2.7.1-alpha and earlier.
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).
This affects clients with FetchUselessDescriptors 1.
It might also cause subtle bugs on directory mirrors and authorities,
causing them to consider all full descriptors as failed or old.
Improve the messages logged when Tor wants or needs to load the master ed25519 identity key so the user is explicitly informed when further action is required or not. Fixes ticket #20650.
