WebdavServlet build changes for compatibility with servletapi-2.3

[Christopher Lenz <cm...@gmx.de>]

Hi all,

I want to propose some changes to the build process of the WebdavServlet, to 
make it possible to compile the servlet against the Servlet 2.3 API. Most 
importantly, we need versions of the classes XHttpServletResponseFacade and 
XHttpServletRequestFacade that have the methods that have been added in 2.3.

To achieve this, I've created two source files for each of the classes, 
appending 22/23 to their file names to identify the servlet-api version. The 22 
versions are unchanged, the 23 versions extend 
HttpServletRequestWrapper/HttpServletResponseWrapper and only override the 
methods actually used for the debug logging. The class names are identical.

The build file chooses which version of the file is needed (using the 
servlet23.present property), copies the correct files and strips the 22/23 
suffix from the filename of the copies. Then during compilation the source files 
with the suffixes are excluded.

So this seems to be working fine here, but I'm not 100% sure if it is a clean 
enough solution. What do you think ?
