[FFe] Upgrade to drupal8

[Nish Aravamudan]

FFe justification: current drupal7 does not support PHP7.0.

We have two paths forward with Drupal in the archive for Xenial:

1) Keep drupal7 but leave it broken until upstream support for PHP7.0 is complete (https://www.drupal.org/node/2454439)

2) Package drupal8 which has PHP7.0 support and is currently passing regular tests.

This is a request to consider the latter before the release.

A test build is at:

https://launchpad.net/~nacc/+archive/ubuntu/php7

which was created with a uscan & uupdated after modificationts to the watch file as in attached tarball.

This seems quite straightforward. drupal8 will be a new source/binary package, so there is zero risk in including it now. I think we shoudl remove drupal7 from xenial then. If some users need it, we can reintroduce it into xenial-updates later on when there's a version that works with php7 again, but I wouldn't ship a known-broken version in release. There are no reverse dependencies to drupal7.

@pitti, agreed on dropping drupal7 if we pick up drupal8. I would appreciate some eyes on if everything is packaged properly, but it was fairly mechanical.

There are actually two revdeps on drupal7, src:drupal7-mod-libraries, which in turn pulls in a bunch of deps that can be removed and src:civicrm. I'll provide a debdiff for the latter, I think the former set should be removed if we remove src:drupal7.

FWIW I don't consider it an obvious win to go with drupal8 in 16.04 rather than leaving drupal7 in, broken, and SRUing the php7 compatibility fixes post-release. Drupal8 being a major new upstream version, there is probably integration testing that would need doing anyway (drupal7 has no autopkgtests), and an unknown amount of packaging changes. To me, it seems that drupal8 for 16.04 implies more work now and more work later.

I accept Martin's judgement that drupal8 is ok for FFe, but as a sponsor I don't believe I can commit to having enough time to following through on this given relative priorities.

100% ack. I wanted to get this bug filed, in case I was told/indicated
this was a better approach.

We can close this bug now that drupal7 with php7 support is in xenial-updates, right?

Yep, thanks!
