As Tomasz noticed, boost::any can be empty, so optional<> functionality is
not needed.

7921ef406a db: serialize via bytes_iterator instead of std::ostream 
Instead of using inefficient std::ostream, use our own 'bytes' iterator class.
Compute ahead of time the length of the byte buffer.
Afterwards serialize the objects into it.

Gives ~X5 boost over previus results (that sometimes don't even
finish in reasonable time)

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.
