Phpunit integration && PHP 7 update

[jclaveau]

Hello, your work seems to still be the best solution for Apache configuration parsing in PHP. As I try to keep safe libs in my projects, I integrated PHPUnit and updated your lib for PHP 7.

I still have one failing test: bug11435-inifile.phpt
But I'm not sure of what I have to do. I need a little help for this case.

This PR could seem big in appearance but is quit simple in fact. I just moved all the old test files to a dedicated directory. All the real modifications to the "business" code are gathered in the first commit: 1a2c2fc

Thanks in advance for your time

Also, if this work fits your expectations, would you please enable this repo in Travis for continuous integration?

These should have went into your global .gitignore.

tests/coverage and clover.xml are specified in the phpunit.xml. Are you sure they should be global?

I have .phpunit.result.cache in pretty much in every other project. Two others are not belong here in the first place. E.g. you can put them into a build folder, then ignore it globally. Or add a local .gitignore with a * in that folder. But I'm just nitpicking here. Great job!

I agree with you concerning .phpunit.result.cache but for the 2 others adding a dedicated folder which itself is ignored looks just as adding out of scope complexity. It could be necessary, if ever a full build process had to be configured, but later, when the build folder would gather more stuff. And taking this in consideration here seems much less important than considering coverage for example.

If you have an example of a build process applied to other Pear packages, I would follow it gladly. Is it the case?

Moreover, would you also enable this repo on https://codecov.io (or any coverage saas) so I could enable it in Travis (passing tests means nothing without coverage)?
