48c11a01db db: Add ability to apply mutations into the database 
For simplicity partition data is stored using the same object which is
used for mutations: mutation_partition. Later we can introduce a more
efficient version.

77b37a7c03 schema: Add column_specification field to schema 
In Origin, some places in CQL3 package treat ColumnDefinition as
ColumnSpecification. Origin solves that by making ColumnDefinition
extend ColumnSpecification.

I find it much simpler to provide an external adapter, which is cached
as a field for efficiency. Another, more important, reason for this
solution is that column_specifications are passed around as
shared_ptrs and I don't want to add unnecessary indirection to
column_definition accesses just because of that, to make it inherit
from column_specification.

654372f368 schema: Allow regular column names to have arbitrary type 
Regular columns may have names of arbitrary type. See
https://issues.apache.org/jira/browse/CASSANDRA-8178

Primary key columns are UTF8.

This change also does some refactoring of the schema object to make
the change easier to digest (more encapsulation).

7f96fc9509 db: read all keyspaces from directory structure 
This patch includes a helper function that executes a function for each entry
in a directory. It is future based and can include in the future, future-based
code to asychronously read, for instance, an sstable.

At the moment, it only scan all keyspaces and make sure they appear in the
keyspaces hash.

Both the database and keyspace classes gain a populate<T> factory that returns a
populated database. At this point, the names found are just listed, but not really
stored anywhere.

e733c2a45a db: change abstract_type::deserialize to allow null objects 
In some cases, deserialize() can return a null object (if there were zero
input bytes).

In others, it cannot (for string or blob types).

Change the return type to optional<any> and adapt the deserialiation code
to deal with it.
