7c5d865aac db: add map_type::serialize_partially_deserialized_from 
Add a way to convert a vector of pairs of serialized key/values to
the fully serializied form; useful for map literals.

fc9a8d6efd db: add collection_type_impl::pack 
A helper function for other operations, as all collections share
the basic serialized format.

3c63f77824 db: split collection_type_impl::mutation into an owning and view types 
The view type is more efficient, but less safe.

0bd44deca9 db: add abstract_type::as_less_comparator() 
Returns a binary predicate that allows comparing two values belonging
to the type, suitable for STL containers and algorithms.

06bd67c221 db: move map_type:impl::mutation and associated helpers to collection_type_impl 
Turns out the sets and lists also use the same data type, with sets using
a fake value type, and lists using a fake key type.

6f2a2529a2 add "double" and "float" types 
Implement "double" and "float" cql types.

This implementation doesn't touch serialization.hh (which should be
eventually removed) and rather follows the other examples in types.cc.
It is relatively ugly, because of all the cleverness of our "general"
byte swapping implementation actually works only for integer types, and
we need to get it to work for float/double as well.

99a09020e8 types: Fix bytes_type_impl string conversion 
Tomek points out that:

  Origin calls org.apache.cassandra.utils.Hex#hexToBytes here, which is
  not what to_bytes() does. BytesType.getSerializer().toString() calls
  ByteBufferUtil.bytesToHex(value), so you should call to_hex() here.

Fix that up.

1f9d22f7e3 types: Fix read_simple*() variants to work for unaligned positions 
Since types can be embedded at any position in memory we cannot assume
alignment.

Side note: It seems that on x86 access to the variable via packed<>
does not result in any extra instructions.

8701273006 Add inet type 
In v2: rebase, and add a more descriptive exception if trying to deserialize
an ipv6 address.

Add to list of types the Internet address type, known as INET in CQL
or as InetAddressType in the Cassandra code.

I based this code on stuff I found in InetAddressType and
InetAddressSerializer in the Cassandra code.

6cde02cbc7 types: Make equal/hash/less work on bytes_view 
The serialized value is not always a standalone "bytes" object, it can
be embedded in a larger chunk. It's much faster to work on the data
in-place.

22b7010c6d types: Introduce non-polymorphic serialization/deserialization helper functions 
All usages I could find which deserialize value are
non-polymorphic. So there is no need to use boost::any() indirection
and polymorphic calls in most, if not all, cases.

Let the type class define deserialize_value/serialize_value
non-polymorphic members which work direclty on "value_type" and not
boost::any.
