ctx: store logger in context when missing or different that stored one (#81) 
Current implementation stores a copy of the logger as a pointer and
update its content, which is now unecessary since the introduction of
WithContext.

The new WithContext now takes the pointer and store it in the context if
none is stored already or if the last one stored is a different pointer.
This way it is still possible to update the context of a logger stored
in the context, but it is also possible to store a copy of the logger in
a sub-context.

Fix #80

1c6d99b455 Add custom error serialization support and provide sane defaults (#78) 
As per https://github.com/rs/zerolog/issues/9 and to offer a different approach from  https://github.com/rs/zerolog/pull/11 and https://github.com/rs/zerolog/pull/35 this PR introduces custom error serialization with sane defaults without breaking the existing APIs.

This is just a first draft and is missing tests. Also, a bit of code duplication which I feel could be reduced but it serves to get the idea across.

It provides global error marshalling by exposing a `var ErrorMarshalFunc func(error) interface{}` in zerolog package that by default is  a function that returns the passed argument. It should be overriden if you require custom error marshalling.

Then in every function that accept error or array of errors `ErrorMarshalFunc` is called on the error and then the result of it is processed like this:
- if it implements `LogObjectMarshaler`, serialize it as an object
- if it is a string serialize as a string
- if it is an error, serialize as a string with the result of `Error()`
- else serialize it as an interface

The side effect of this change is that the encoders don't need the `AppendError/s` methods anymore, as the errors are serialized directly to other types.

77db4b4f35 Embed the diode lib to avoid test dependencies 
This commit introduces a breaking change in the diode API in order to
hide the diodes package interface. This removes a good number of
dependencies introduced by the test framework used by the diodes
package.
