This change removes the commentary about the admin
database since it no longer applies when using role
based authentication in MongoDB 2.4 and newer.
Consult the MongoDB manual for details.
This is initially for LDAP authentication support in
MongoDB 2.6 (forthcoming). Warning: the username and
password are sent over the wire in clear text per
RFC 4616. SSL with cert validation should be used in
conjunction with the PLAIN mechanism to encrypt the
channel.
This only works with the subscriber addition of MongoDB
>= 2.4 and requires the python "kerberos" module, sometimes
referred to as pykerberos.

This change also adds support for the authMechanism
and authSource URI options.
This change deprecates get|set|unset_lasterror_options,
replacing them with a write_concern attribute that can be
accessed directly. See the write_concern docstring for
an example of its use.
Replace the 'mongo' dict with a Member object everywhere in ReplicaSetConnection.
A handful of commands obey read preferences; most are always sent to primary.
Track a 5-sample moving average of each replica set member's ping time.
Connection detects whether it's connected to primary, secondary, or mongos.
Big change to PyMongo connection pooling:
* While we still allocate a socket per thread by default, this is now optional. It is also possible to share sockets among threads, safely, and thus using fewer total sockets, by creating a Connection or ReplicaSetConnection with auto_start_request=False.
* In the past, when a thread died without calling end_request() its socket was closed. We now reclaim such sockets for the pool, which should reduce connection churn.
* start_request() now returns a context manager so you can do "with connection.start_request():"
* ReplicaSetConnection now supports start_request, although its semantics aren't consistent for ReadPreferences other than PRIMARY
* Refactoring: Connection and ReplicaSetConnection had different pool implementations, now they share one.
