Title:
  Zabbix Frontend fails install with PHP7.0 due to
  always_populate_raw_post_data configuration

Status in zabbix package in Ubuntu:
  Fix Released
Status in zabbix source package in Xenial:
  Fix Released

Bug description:
  [Impact]

   * The zabbix web frontend has one incompatibility and some missing
  dependencies with PHP7.0.

   * End-users are unable to use the web-frontend due to these issues.

  [Test Case]

   * Install zabbix-frontend-php. Without the fix, the frontend will not
  load properly. With the fix, it will.

  [Regression Potential]

   * The code change is identical to the upstream change; given that the
  frontend won't load with the code as-is, I believe there is no
  regression potential there.

   * The dependency changes allow for the web frontend to work properly
  without extra packages needing to be manually installed by end-users.
  Again, no chance for regression.

  always_populate_raw_post_data was deprecated in PHP 5.3 at which time
  zabbix frontend setup began to insist that it be set to
  always_populate_raw_post_data = -1 in the PHP.ini

  In PHP 7.0, which Ubuntu 16.04 LTS ships with,
  always_populate_raw_post_data has been removed completely.  Due to
  this PHP frontend setup gets stuck on always_populate_raw_post_data
  not being disabled.

  The solution is to apply the following patch to the PHP frontend code
  to ignore PHP 7.0:
