[php-maint] PHP 5 to PHP 7.0 transition and change of PHP packaging to allow coinstallable versions

[Gert Wollny]

Hi all, 

[...]
  9. We expect to ship next Debian release (stretch) only with PHP
>      7.0, that means that all packages needs to be made compatible
>      with PHP 7.0.  
[...]

Mathieu [gdcm upstream] just pointed out to me that Swig does not yet
support PHP 7.0 [1], which means that for the time being packages that
rely on it to create the language bindings will not be able to support
it. 

Best, 
Gert
