Starting with commit 61a298c39c we delay the
signal handler setup until after lots of other initialization has happened,
which can result in us having very large (>1024) open fds, which will
break the FD_SET macros for select(2). Use poll(2) instead.

If we try to open an mds session and the MDS responds with close (aka,
"no"), we call _closed_mds_session() which signals the Cond*'s but then
deallocates the list. wait_on_list() then does a use-after-free trying
to remove itself.
Instead, use Context*'s, so that the waiter does not reference the list.

These are better when the list may need to be deallocated. Context's are
single-shot and the list is not referenced by the caller.

After cluster creation, we have no full map stored and first_committed ==
1. In that case, there is no need for a full map, since we can get there
from OSDMap() and the incrementals.

In 7fb3804fb8 we moved the full version
stashing logic to the encode_trim_extra() function. However, we forgot
to update the osdmap's 'latest_full' key that should always point to
the latest osdmap full version. This eventually degenerated in a missing
full version after a trim. This patch works around this bug by looking
for the latest available full osdmap version in the store and updating
'latest_full' to its proper value.

We used to do this on encode_full(), but since [1] we no longer rely on
PaxosService to manage the full maps for us. And we forgot to write down
the latest_full version to the store, leaving it in a truly outdated state.

When forwarding a swift request to a different region, we
need to use the effective uri, and not just send the one
we got since we use S3 authentication for the forwarded
requests. This is achieved through a new using 'effective_uri'
param on the request info (which in swift ponts to the
plain bucket/object uri without the swift/v1 prefix(.
Also, rename the old req_state::effective_uri to relative_uri
in order to prevent confusion.

Currently doing it only when copying between regions. This is
needed so that the operation doesn't time out (as it can take
a long time and the web server may just hang on us since we're
not sending any data).
This is configurable and can be disabled. Currently only implemented

During the collect/last exchange, peers share any uncommitted values
with the leader. They are supposed to also share the pn under which
that value was accepted, but were instead using the just-accepted pn
value. This effectively meant that we *always* took the uncommitted
value; if there were multiples, which one we accepted depended on what
order the LAST messages arrived, not which pn the values were generated
under.
The specific failure sequence I observed:
- collect
- learned uncommitted value for 262 from myself
- send collect with pn 901
- got last with pn 901 (incorrect) for 200 (old) from peer
- discard our own value, remember the other
- finish collect phase
- ignore old uncommitted value
Fix this by storing a pending_v and pending_pn value whenever we accept
a value. Use this to send an appropriate pn value in the LAST reply
so that the leader can make it's decision about which uncommitted value
to accept based on accurate information. Also use it when we learn
the uncommitted value from ourselves.
We could probably be more clever about storing less information here,
for example by omitting pending_v and clearing pending_pn at the
appropriate point, but that would be more fragile. Similarly, we could
store a pn for *every* commit if we wanted to lay some groundwork for
having multiple uncommitted proposals in flight, but I don't want to
speculate about what is necessary or sufficient for a correct solution
there.

If an older peer sends an uncommitted value, make sure we only take it
if it is in the future, and at least as new as any current uncommitted
value.
(Prior to the previous patch, peers could send values from long-past
rounds. The pn values are also bogus.)
