Change in ovirt-engine-sdk[master]: codegen: Avoid calculation of singulars and plurals

Juan Hernandez has submitted this change and it was merged. Change subject: codegen: Avoid calculation of singulars and plurals ...................................................................... codegen: Avoid calculation of singulars and plurals Currently the code generator assumes that there is a semantic relationship between the names of XML schema complex type that represent collections and entities: the name of the entity is the plural of the name of the collection. To handle this it uses rules to calculate the plurals from singulars, and the other way around. But for some collections and entities simple calculation of plural and singular (adding or removing a trailing "s") doesn't work. For example: SchedulingPolicies -> SchedulingPolicy Another example is the following, which has been introduced in the server side: KatelloErrata -> KatelloErratum The code generator also assumes that the names of the XML schema complex types match the URL segments. This doesn't always work. For example, with the recent addition of external providers to the server side there are URL segments like this one: /externalhostproviders/{externalhostprovider:id}/hosts The XML complex type corresponding to this "hosts" collection is "ExternalHost", and not "Host" as the existing rules expect. We have been handling these situations adding exceptions in the code of the generator, and implementing more robust rules for calculations of plurals and singulars, but this doesn't scale well, and it is prone to unexcpected failures. To avoid these issues in a more systematic way this patch modifies the generator so that it will extract the required information from the XML schema and the RSDL instead of making calculations. The core of this change is the introduction of a tree data structure that stores the links extracted from the RSDL, so that it is easy to find from one node its children and parents. This data structure is used to decide if a location corresponds to a collection, entity or action, and combined with querying the XML schema to extract the type names.
