Rework replication protocol
...
This change exposes lower level functions for operating the
(logical) replication protocol, while keeping the high-level
start_replication function that does all the job for you in
case of a synchronous connection.
A number of other changes and fixes are put into this commit.

Add support for streaming replication protocol
...
Introduce ReplicationConnection and ReplicationCursor classes, that
incapsulate initiation of special type of PostgreSQL connection and
handling of special replication commands only available in this special
connection mode.
The handling of stream of replication data from the server is modelled
largely after the existing support for "COPY table TO file" command and
pg_recvlogical tool supplied with PostgreSQL (though, it can also be
used for physical replication.)

Add parse_dsn module function
...
Calls PQconninfoParse to parse the dsn into a list of keyword and value
structs, then constructs a dictionary from that. Can be useful when one
needs to alter some part of the the connection string reliably, but
doesn't want to get into all the details of parsing a dsn string:
quoting, URL format, etc.

Allow pickling of cursor.description
...
This is for people using dtuple.py; a dtuple.DatabaseTuple instance
keeps a reference to cursor.description, which is not picklable because
psycopg2 doesn't export the Column namedtuple it uses.
This commit exports the Column namedtuple, and includes a test to verify
the pickle/unpickle works after exporting Column.
