- introcduced "seastarx.hh" header, which does a "using namespace seastar";
- 'net' namespace conflicts with seastar::net, renamed to 'netw'.
- 'transport' namespace conflicts with seastar::transport, renamed to
cql_transport.
- "logger" global variables now conflict with logger global type, renamed
to xlogger.

This changes announce_migration() to return a change event directory in
schema_altering_statement base class. It's needed for drop index
statement, which does not know the keyspace or column family until it
looks up them based on the index. Two stage approach of announcing a
migration and then creating the change event won't work because in the
latter stage, the lookup will fail. The same change in
announce_migration() has been applied to Apache Cassandra.
Use seastar::checked_ptr<weak_ptr<pepared_statement>> instead of shared_ptr for passing prepared statements around.
This allows an easy tracking and handling of statements invalidation.
This implementation will throw an exception every time an invalidated
statement reference is dereferenced.

To prepare for the separation of prepared and raw schema_altering_statements,
avoid the reliance this class implementing both the raw and prepared
variants and the use of shared_from_this().
We need to capture the "is_local_only" boolean by value because it's an
argument to the function. Fixes an annoying bug where we failed to update
schema version because we pass "true" accidentally. Spotted by ASan.
