Remove inherited create() method + disallow copying
...
The original motivation for this commit was that shared_ptr_helper used
std::shared_ptr<>() which does two heap allocations instead of
make_shared<>() which does a single allocation. Turned out that
1. the affected code (--> Storages/) is not on a hot path (rendering the
performance argument moot ...)
2. yet copying Storage objects is potentially dangerous and was
previously allowed.
Hence, this change
- removes shared_ptr_helper and as a result all inherited create() methods,
- instead, Storage objects are now created using make_shared<>() by the
caller (for that to work, many constructors had to be made public), and
- all Storage classes were marked as noncopyable using boost::noncopyable.
In sum, we are (likely) not making things faster but the code becomes
cleaner and harder to misuse.

Avoid MEMORY_LIMIT_EXCEEDED during INSERT into Buffer with AggregateFunction
...
In case of Buffer table has columns of AggregateFunction type,
aggregate states for such columns will be allocated from the query
context but those states can be destroyed from the server context (in
case of background flush), and thus memory will be leaked from the query
since aggregate states can be shared, and eventually this will lead to
MEMORY_LIMIT_EXCEEDED error.
To avoid this, prohibit sharing the aggregate states.
But note, that this problem only about memory accounting, not memory
usage itself.
