Use a temporary service list when validating and adding hidden services
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.

f80a43d16f Stop ignoring hidden service key anonymity when first starting tor
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).
