Add PHP 7.2 support, drop HHVM

[Slamdunk]

• Cherry-pick fix for phpunit 6 #141
• Adopt recent .travis.yml ZF standards (zend-session/.travis.yml picked)
• Drop HVVM
• Test PHP 7.2
• Add partial PHP 7.2 support
  1. Fatal error: Declaration of Zend\InputFilter\CollectionInputFilter::isValid() must be compatible with Zend\InputFilter\BaseInputFilter::isValid($context = NULL) in /tmp/zend-inputfilter/src/CollectionInputFilter.php

LGTM 👍

The failing tests for the nightly build are related to Zend\Validator\EmailAddress and idn_to_ascii.

@froschdesign thank you, zendframework/zend-validator#175

[Slamdunk]

Note that

Because

zend-inputfilter/composer.json

Line 18 in 9569f7e

"zendframework/zend-validator": "^2.6",

And zend-validator compatibility with PHP 7.2 was introduced only in zend-validator ^2.10 release

@Slamdunk Maybe then we should bump requirements in composer.json?

[Slamdunk]

This is a decision that I cannot take, only maintainers know the path of expected components support.

Any ETA for merging this PR?

@MatyCZ I'm merging it today, but it won't release yet, as I have a PR or two I'm sitting on for the 2.8.0 release (primarily waiting for docs). This cannot release in a bugfix release, as it drops support for HHVM.

Thanks, @Slamdunk!
