Previously we created a default bean definition for MongoMappingContext if none was present in the application context. That lookup for an existing one unfortunately comes too early, especially with Spring Boot in place. This then caused the MappingContext not being aware of the custom conversions and simply types registered by Boot.
We now removed the defaulting relying on a MappingMongoConverter being present in the Application context (which usually is the case for the usage with AbstractMongoConfiguration or the XML <mongo:mapping-converter /> alternative. We use that bean to lookup the MappingContext.
We now use DbObjectAccessor also for preliminary inspections of the source DBObject (e.g. whether a value is present at all). Previously we operated on the DBObject directly which caused issues with properties mapped to nested fields as the keys weren't exploded correctly and thus the check always failed.
By turning `AggregationExpression` public we allow adding custom expressions without workarounds. It is now possible to create eg. `ProjectionOperation` like:
ProjectionOperation agg = Aggregation.project()
.and(new AggregationExpression() {
@Override
public DBObject toDbObject(AggregationOperationContext context) {
DBObject filterExpression = new BasicDBObject();
filterExpression.put("input", "$x");
filterExpression.put("as", "y");
filterExpression.put("cond", new BasicDBObject("$eq", Arrays.<Object> asList("$$y.z", 2)));
return new BasicDBObject("$filter", filterExpression);
}
}).as("profile");

We now take potential registered converters for enums into account when serializing path expressions via SpringDataMongodbSerializer.

We now propagate the PersistentEntity when mapping nested keywords so that the criteria mapping chain for nested keywords and properties has now access to the PersistentEntity and can use configured field names.
Previously the plain property names have been used as field names and potential customizations via @Field have been ignored.

Replace boolean flag in convertAndJoinScriptArgs with literal. Joined args are rendered to JavaScript and require always string quotation.

Setting the value for the identifier property is an explicit step in MappingMongoConverter and always executed if the type to be created has an identifier property. If the source document doesn't contain an _id field (e.g. because it has been excluded explicitly) that previously caused null to be set on the identifier. This caused an exception if the identifier property is a primitive type.
We now explicitly check whether the field backing the identifier property is actually present in the source document and only explicitly set the value if so.
This should result in minor to moderate performance improvement for iteration on Collections/Arrays during DBObject to object mapping.

We now preserve the cause of Exceptions that cannot be translated into DataAccessExceptions when an error occurs during lazily loading DBRefs.

Fixed broken highlighting using backticks followed by chars/single quotes. Convert single quote emphasis of id to backtick code fences. Add missing spaces between words and backticks.

We now start MongoDB server via apt-get instead of relying on the TravisCI managed 2.4.2 installation.
Doing this we altered tests to just check on the port and not the host part of the URIs.
Additionally we upgraded build profiles, removed promoted snapshot-versions, renamed mongo32-next to mongo32 and added mongo33-next build profile.
