OpenDaemon

This release continues the evolution of the system into a generic server platform so it can support the advanced data storage solution that's intended to be plugged into it in the future. Among the major modifications are generalization of the engine API such that support for any storage format is provided, and a full rewrite of the configuration system.

The goal has changed from creating a native XML database server to
creating a strong heart of data storage software in general. This
release goes in this direction by providing a lot of foundation
modifications. OpenXMLD can now support multiple client interfaces
(interface = query parser + tree walker + response translator) and
assign a different interface to each of its listening sockets. XMLDSQL
and Engine-XMLD have not been dropped; they still exist in the code and
they are going to be launched as separate projects at a later point.

The code has undergone a lot of enhancements since the last release: most notably, a specification and an implementation of a communication protocol, and much more consideration of multi-levelling within XMLD-SQL.

This is the first alpha and usable release of The OpenXMLD. It mainly
implements all the lacking parts in the request/response cycle.
Switching of the multi-processing module during compilation is now
possible, but the only module currently implemented is ptasker, a
preforker. This release also contains an implementation of the xmld-sql
query language parser and Engine-XMLD, a high-performance on-disk XML
processing engine.

This release contains a full configuration system, a skeleton engine
(Engine-XMLD), and support for using multiple engines which can even
be switched for the same file on the fly, representing the possibility
of processing any kind of documents as long as their MIME type has a
supporting engine installed (even SQL tables). A lot of bugfixes and
consistency preparations across all the code have been carried out. A
running OpenXMLD is around the corner.
