Upload last SVN ptlib, opal to experimental

[Eugen Dedu]

Hi,

I have finished the diff.gz for ptlib (pwlib) and opal and put them in 
{pwlib/opal}/branches/experimental on alioth.

Usage: as shown in get-orig-source, in order to build you check out the 
SVN {ptlib/opal} repositories, grab the changelog, remove the .svn 
directories, apply debian patch and execute debuild&Co.

For info, my .build files are available at 
http://eugen.dedu.free.fr/debian (please don't consider lintian warnings
for .svn).

Questions whose answer I don't know:

- I called binaries libpt-2.3 etc. and libopal-3.3; however, the soname
are libpt.so.2.3-beta1 and libopal.so.3.3-beta1; I suppose this is ok
(developers have not answered for ABI changing, but as it is about a
beta, I suppose the ABI won't break (so much))

- the version is 0.svn2008MMDD-1 (like ffmpeg package), is it ok?

- dfsg should be added to opal name because of the removal of iLBC

- in rules, get-orig-source is commented out for the moment

- where the .svn directories should be removed in rules file: in 
get-orig-source, in clean or in install/binary-common/... stuff?

- I didn't know for Uploaders and Maintainer fields (control file) what 
to put exactly

Best regards,
Eugen Dedu
