db: Extract bytes related stuff from database.cc to bytes.cc
...
Some tests (eg murmur_hash_test) need only byte manipulation
functions. By specifying dependencies precisely we can drastically
reduce recompilation times, which speeds up development cycle.
I managed to reduce recompilation time for murmur_hash_test from 5
minutes to 4 seconds by breaking dependency on whole urchin object
set.

Also replace derived types (map_type, collection_type, etc.).
As we'll change data_type's definition, this reduces the number of places
that need to be modified later, and is more readable.

db: make bytes even more distinct from sstring
...
bytes and sstring are distinct types, since their internal buffers are of
different length, but bytes_view is an alias of sstring_view, which makes
it possible of objects of different types to leak across the abstraction
boundary.
Fix this by making bytes a basic_sstring<int8_t, ...> instead of using char.
int8_t is a 'signed char', which is a distinct type from char, so now
bytes_view is a distinct type from sstring_view.
uint8_t would have been an even better choice, but that diverges from Origin
and would have required an audit.

cql3: de-virtualize cql3_type
...
cql3_type is a wrapper around data_type, so there's no need for a class
hierarchy -- anything that depends on the actual type can be forwarded
to abstract_type_impl.
We can now use this as a value type (dropping shared_ptr<cql3_type>), but
that is left for later.
