Currently when reading a view to an object the stream stored has the
same bound as the containing stream, not the bounds of the object
itself. The serializer of the view assumes that the stream has the
bounds of the object itself.

The segment->segment_manager pointer has, until now, been a raw pointer,
which in a way is sensible, since making circular shared pointer
relations is in general bad. However, since the code and life cycle
of segments has evolved quite a bit since that initial relation
was defined, becoming both more and then suddenly, in a sense,
less, asynchronous over time, the usage of the relation is in fact
more consistent with a shared pointer, in that a segment needs to
access its manager to properly do things like write and flush.
These two ops in particular depend on accessing the segment manager
in a way that might be fine even using raw pointers, if it was not
again for that little annoying thing of continuation reordering.
So, lets just make the relation a shared pointer, solving the issue
of whether the manager is alive when a segment accesses it. If it
has been "released" (shut down), the existing mechanisms (gate)
will then trigger and prevent any actual _actions_ from taking
place. And we don't have to complicate anything else even more.
Only "big" change is that we need to explicitly orphan all
segments in commitlog destructor (segment_manager is essentially
a p-impl).
This fixes some spurious crashes in nightly unit tests.
Fixes#966.

We cannot use shared_ptr *instances* for checking duplicate column

When the first time the keep alive timer fires, the _last_stream_bytes
btyes will be zero since it is the first time we update it. The keep
alive timer will be rearmed and fired again. The second time, we find
there is no progress, we close the session. The total idle time will be
2 * keep alive timer.
To make the idle time to close the session be more precise, we reduce
the interval to check the progess and close the session by checking last
time the progress is made.

Checking schema::is_dense() is not enough to know whether row marker
should be inserted or not as there may be compact storage tables that
are not considered dense (namely, a table with now clustering key).
Row marker should only be insterted if schema::is_cql3_table() is true.

Unlike CentOS/Fedora, scylla_io_setup is calling from pre-start section of scylla-server upstart job, not from separated job.

This patch change the way optional vector are implemented.
Now a vector of optional would be handle like any other non primitive
types, with a single method add() that would return a writer to the
optional.
The writer to the optional would have a skip and write method like
simple optional field.
For basic types the write method would get the value as a parameter, for
composite type, it would return a writer to the type.

To report disk usage, scylla was only taking into account size of
sstable data component. Other components such as index and filter
may be relatively big too. Therefore, 'nodetool status' would
report an innacurate disk usage. That can be fixed by taking into
account size of all sstable components.

See code comment. Reserve segment allocation count sum can temporarily
overflow due to continuation delay/reordering, if we manage to reach the
on_timer code before finally clauses from previous reserve allocation
invocation has processed. However, since these are benign overflows
(just indicating even more that we don't need to do anything right now)
simply capping the count should be fine.
Avoids assert in boost irange.

We require SSE 4.2 (for commitlog CRC32), verify it exists early and bail
out if it does not.
We need to check early, because the compiler may use newer instructions
in the generated code; the earlier we check, the lower the probability
we hit an undefined opcode exception.

It is used by

If an api operation inside storage_service takes a long time to finish
, which holds the lock, it will block nodetool status for a long time.
I think it is safe to get the load map even if other operations are in-flight.

By initilizing them to 0 we can catch unclosed frames at
deserialization time. It's better than leaving frame size undefined,
which may cause errors much later in deserialization process and thus
would make it harder to identifiy the real cause.
