Make the logic match the intent described in the comments.
The intent is clearly "accept notices whenever (A or B or C)", but
the logic implemented was more like "not ((not A) or (not B) or (not C))",
which is a basical boolean algebra fail (each of those ORs need to
become ANDs for double-negation to work).
The practical implication was that, for example, writing a reply
to someone else's notice and including an @-reference to _another_
user on another site to bring them into the discussion would
fail to deliver the notice to the new user because their server
would basically say `oh no, you can't message this user
from someone else's thread' because an earlier check for
the `A' or `C' parts of `(A or B or C)' prevents `B' from
being checked.
cf.: <http://status.hackerposse.com/notice/55846>, which was
refused by the nhcrossing.com server because it didn't know
about <http://sn.jonkman.ca/notice/93724>, even though it would
have passed the later `notice contains a reference to a local user'
check if not for an exception being prematurely thrown.
The whole idea of reporting `which specific check FAILED'
in an `if ANY SUCCEEDS' analysis is just bogus, so nix all of
the distinct ClientExceptions--a single `ALL FAILED' exception
is the only one that makes sense.
There was a problem with (specifically at least) PuSHpress for
Wordpress. A previous attempt to perform a DB transaction backfired
because the remote side could connect to the callback before our
commit had gone through.
I take full responsibility for introducing the bug in the first place :)
Among other things (such as permanent subscriptions), Pubsubhubbub 0.4
removed the "sync" verification method. This means that any incoming
PuSH subscription requests that follow the 0.4 spec won't really
_require_that we handle it as a background process, but if we were to
try direct verification of the subscription - and fail - there's no way
we could pick up the ball again. So _essentially_ we require background
processing with retries.
This means we must implement something like the "poorman cron" or
similar, so background processing can be handled
on-demand/on-site-visit. This is how Friendica, Drupal etc. handles it
and is necessary for environments where we can't run separate queue
daemons.
When the poorman-cron-ish thing is implemented, auto-renewal will work
for all users.

This is more of a proof of concept and will likely not stay in exactly
this form. We should reasonably deliver the entire notice upon webfinger
querying.
Also removed the entirely unused saveGroups function.
Now avoiding multiGet and using listFind in Profile->getGroups()
so we don't have to deal with ArrayWrapper.
"[...] posts _local_ users (like you) make won't get data about "repeated by"
from federated users"
This was because the ActivityObject would processShare where the shared object
has a _local_ 'actor' URI. Ostatus_profile would complain this meant that a
"Local user cannot be referenced as remote.".
So we see if the shared activity object's id (URI) is in our Notice table, so
we don't have to processActivity - and can skip ensureActivityObjectProfile.
