61e52ce879 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.

e32e1b834e 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.)

6c57e4a648 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.

5af5fb4cc6 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.

The implementation is based on psycopg 2.4, which should be less broken

Instantiating psycopg2.pool.PersistentConnectionPool now raises a warning.

This should fix ticket #123, #125. The issue of the reset on
set_client_encoding() is still present but that's always been there and I'm no
good at fixing it.

20d3d0f66d Raise TypeError instead of InterfaceError on bad params on connect() 
TypeError is the standard Python error raised in this case:

    $ python -c "(lambda a: None)(b=10)"
    TypeError: <lambda>() got an unexpected keyword argument 'b'

We only used to raise InterfaceError when connect was used without
any parameter at all, so it's hard to think a program depending on
that design. Furthermore the function has always raised (and still
does) OperationalError too, if the bad argument is detected by the
libpq, and that cannot be changed because we can't tell the
difference from a normal connection error.

095cce5605 Allow user to override connection factory cursors 
Prior to this change, using a extras.connection_factory would not allow
any other cursor to be used on that connection. It was set in stone.

This change allows all cursor options to pass through and override the
connection factory behaviors. This allows a connection_factory to be
dropped into existing code with no disruption.

This change also standardizes the extras.connection_factories to have
the same behavior and all pass through *args and **kwargs.

cb1d163f4f lazy import for uuid module 
Attached patch moves uuid import from inside try-except
to register_uuid function.  Reason: uuid module import is *very*
heavy.  It goes into OS searching for various .dll/.so libraries,
lauches 'ldconfig' and so on...

With this patch, 200x python -c 'import psycopg2.extras'
goes from 22s to 7s.  (plain 'import psycopg2' is 6s)

Added an adapter for None: it is usually not invoked as adaptation to
NULL is a fast path in mogrify, but can be invoked by composite types.

(e.g. list adapter does).

01799e9137 Make asynchronous connections produce asynchronous cursors by default 
Drop the async kwarg from cursor.execute(), cursors created by
asynchronous connections will be asynchronous by default, ones created
by synchronous connections will be synchronous.

Mind that this might break third party subclasses of
psycopg2.extensions.cursor, if they try to chain to the superclass in
their execute() implementation and are passing the async kwarg. The
example cursors in psycopg2.extras have been fixed no to do that.

34317dc4c3 Support asynchronous connection building 
After calling psycopg2.connect(dsn, async=True) you can poll the
connection that will tell you whether its file descriptor should be
waited on to become writable or readable or that the connection
attempt has succeeded.

Edited commit by Jan to not expose internal state in extensions.py.
