bc9ee083dd db: Move atomic_cell_or_collection to separate header 
To break future cyclic dependency:

  atomic_cell.hh -> schema.hh (new) -> types.hh -> atomic_cell.hh

ad975ad629 atomic_cell_or_collection: linearize(), unlinearize() 
Add linearize() and unlinearize() methods that allow making an
atomic_cell_or_collection object temporarily contiguous, so we can examine
it as a bytes_view.

79f7431a03 db: change collection_mutation::{one,view} not to use nested classes 
Nested classes cannot be forward-declared, so change the naming
not to use them.  Follows atomic_cell{,_view}.

831cdf74c4 db: Avoid allocation of temporary bytes object 
We're storing data inside managed_bytes now, so conversion to "bytes"
is futile.

c4acdb2068 db: Switch from bytes to managed_bytes for storing data 
We need a container which can be used with compacting
allocators. "bytes" can't be used with compacting allocator because it
can't handle its external storage being moved.

eaceb61801 db: Add atomic_cell::deletion_time() 
Deleted cells store deletion time not expiry time. This change makes
expiry() valid only for live cells with TTL and adds deletion_time(),
which is inteded to be used with deleted cells.

b1e45e4401 db: Store ttl in atomic_cell 
Origin does that, so should we. Both ttl and expiry time are stored in
sstables. The value of ttl seems to be used to calculate the read
digest (expiry is not used for that).

The API for creating atomic_cells changed a bit.

To create a non-expiring cell:

  atomic_cell::make_live(timestamp, value);

To create an expiring cell:

  atomic_cell::make_live(timestamp, value, expiry, ttl);

or:

  // Expiry is calculated based on current clock reading
  atomic_cell::make_live(timestamp, value, ttl_optional);

5ba1486ae7 db: Rename "ttl" to "expiry" when it's used as time point

This patchsets completes the conversion of scalar functions (TOKEN is still
missing, and maybe others, but the infrastructure is there).

6f6f924c9c Serializer object(s) for internal use 
For serializing to commit log, and potentially internal wire messaging.

Note: intentionally incompatible with stock C wire/serial format.

Note: intentionally separate from the CQL-centric serialization
for a few reasons.

1.) Need "bulk serializers" for internal objects (mutation etc)
which might not fit well into the "types.hh" serializer schemes.
2.) No need for polymorphism/virtual type parameters since we know
exactly what we serialize and to where.

2f8be37fca atomic_cell_or_collection: allow construction from atomic_cell

we can allow direct conversion.  Type information is only lost, not added.
