b7cf3a679d Convert ThriftValidation.validateColumnFamily(String,String) 
Unlike origin, we don't use global singleton, but accept a database
reference instead.

c75468160a db: Use memcmp for comparing bytes 
My bench-lie shows it's:
  - 1.2x faster for values of size 4 bytes
  - 4x faster for values of size 16 bytes
  - 9x faster for values of size 64 bytes

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.

1fe6bf687d db: de-pimpl data_type 
Since origin tends to cast around, we should allow that too, by exposing
the implementation type and using a shared_ptr instead of a value class.

efc868d1e6 db: extend data_type to be able to support dynamic types 
Dynamic types come and go, so they need to be reference counted.

Switch data_type to using a shared_ptr<> for its implementation.

Since thread_ptr is not thread safe, the global primitive types must be
thread_local.

2733813c87 db: add a "bytes" type, corresponding to ByteBuffer (serialized values) 
Using sstring can lead to confusion with UTF8 strings.

The Java byte type is signed, so make bytes' internal type be signed as
well (even though Cassandra tries to treat it as unsigned).

While we should use int8_t, sstring is not perfectly compatible with this
yet, so add a FIXME and use char instead.
