Chemistry updates

[Florent Guillaume <fg...@nuxeo.com>]

Hi Chemists,

I've now updated the Chemistry codebase in Apache svn to the latest of  
what we have in our Nuxeo mercurial repository.

Here's an outline of the main changes:
- flattened chemistry-api package for simplicity, no more type/,  
property/ and repository/ subdirectories,
- introducted ObjectId class, used by the SPI whenever an object id is  
expected,
- ObjectEntry and CMISObject are now two distinct interfaces  
(CMISObject doesn't inherit from ObjectEntry); both extend ObjectId,
- ObjectEntry is now a very simple interface, intended to be used as a  
data transfer object (DTO) by the SPI,
- Connection methods parameters have been specialized to use Folder,  
Document, etc. when appropriate,
- PropertyType is now a class and not an enum, to allow  
implementations to extend it for specialized cases,
- a few generic abstract classes (BaseObject, BaseRepositoy) have been  
extracted from the "simple" in-memory backend into  
org.apache.chemistry.impl.base, they can be useful for many  
implementations,
- deleteObject and deleteTree now implemented in "simple" in-memory  
backend,
- new chemistry-ws module which for now only generates the Java  
bindings from the WSDL using CXF and the maven cxf-codegen-plugin.

Note that all future changes we plan to make will be tied to JIRA CMIS  
issues and described there.
One of the first I'll do, maybe tonight/tomorrow, is to move a number  
of the Connection methods directly onto Document or Folder.

Cheers,
Florent

PS: FYI I'm leaving for one week of vacation on Sunday, where I won't  
have internet access. So I will be incommunicado next week :)
