Please remove php-sabredav and kopano-webapp-files

[Bryce Harrington]

The php-sabredav package is blocking migration for php-defaults. It appears not sufficiently actively maintained upstream, at least, there has been little recent activity. Notably is this blog post:

  https://evertpot.com/sabredav-eol/

There's been no recent commits, last one was a couple years ago:

  https://github.com/fruux/sabre-dav/commits/master

The problem currently seen in the archive is a test failure with the package we've been shipping, which I suspect is originating either from the php7.4 update, or (more likely) recent phpunit updates:

  There were 2 errors:

  1) Sabre\DAV\Auth\Backend\AbstractDigestTest::testAuthenticateNoHeaders
  Trying to access array offset on value of type bool

  /usr/share/php/Sabre/HTTP/DigestAuth.php:125
  /usr/share/php/Sabre/DAV/Auth/Backend/AbstractDigest.php:61
  /tmp/autopkgtest.d1pom5/build.dS6/src/tests/Sabre/DAV/Auth/Backend/AbstractDigestTest.php:22

  2) Sabre\HTTP\DigestAuthTest::testInvalidDigest2
  Trying to access array offset on value of type bool

  /usr/share/php/Sabre/HTTP/DigestAuth.php:136
  /usr/share/php/Sabre/HTTP/DigestAuth.php:100
  /tmp/autopkgtest.d1pom5/build.dS6/src/tests/Sabre/HTTP/DigestAuthTest.php:164

As it happens there is a new major release in Debian experimental. We're shipping version 1.8.12-8, which is current with Debian unstable. Debian experimental has 3.2.0-1; unfortunately it has some other php-sabre-* dependencies not directly resolvable.

Only a single thing depends on this package, kopano-webapp-files, and nothing depends on it:

$ apt-cache rdepends php-sabre-dav
php-sabre-dav
Reverse Depends:
  kopano-webapp-files

$ apt-cache rdepends kopano-webapp-files
kopano-webapp-files
Reverse Depends:

We have been able to preserve most of the Kopano framework with php7.4, but this plugin looks like it may need to be dropped at this point.
