Includes:

  • Improved bson.Raw unmarshalling performance (details)
  • Minimise socket connection timeouts due to excessive locking (details)

Of note is #52 which should help reduce (but not eliminate) socket errors which seem fairly common (e.g. #21, https://github.com/go-mgo/mgo/issues/473, https://github.com/go-mgo/mgo/issues/498, etc).

Thanks for the contributions from:

Fix #30.

Thanks to @feliixx for the time and effort.
* Stop all db instances after tests (go-mgo#462)

If all tests pass, the builds for mongo earlier than 2.6 are still failing.
Running a clean up fixes the issue.

- Allow specifying the default collation for the collection when creating it.
- Add some documentation to query.Collation() method.

* Adds missing collation feature description (by @feliixx).

readme: add missing feature descriptions / credit
* Fix GetBSON() method usage

Original issue
---

You can't use type with custom GetBSON() method mixed with structure field type and structure field reference type.

For example, you can't create custom GetBSON() for Bar type:

```
struct Foo {
	a  Bar
	b *Bar
}
```

Type implementation (`func (t Bar) GetBSON()` ) would crash on `Foo.b = nil` value encoding.

Reference implementation (`func (t *Bar) GetBSON()` ) would not call on `Foo.a` value encoding.

After this change
---

For type implementation  `func (t Bar) GetBSON()` would not call on `Foo.b = nil` value encoding.
In this case `nil` value would be seariazied as `nil` BSON value.

For reference implementation `func (t *Bar) GetBSON()` would call even on `Foo.a` value encoding.

* Minor refactoring
This change remove full BSON decoding on:

 - parsing to `bson.Raw` and `bson.DocElem` fields;
 - skipping unused BSON fields.
