[Form] corrected interface bind() method defined against in deprecation ...

...notice

The 'bind' method is defined against `FormInterface` not `FormConfigInterface`. This corrects the deprecation notice in the `Form` implementation.

4139936 [DomCrawler] Fix handling file:// without a host
fix issue where $_ENV contains array vals

There are cases where $env or $_ENV can contain a value that is an array
This will cause Process to throw an Array to String conversion exception
Initially I submitted a patch of Process.php, however Fabien indicated
that it shouldn't be fixed there (see below pull request).

Before recently, a simple work around would be in php.ini to set:

  register_argc_argv = On

However with recent changes, this seems to no longer work.

Original pull request: https://github.com/symfony/symfony/pull/7354

See ticket https://github.com/symfony/symfony/issues/7196
merged branch oodle/ticket_7196 (PR #8227)

This PR was submitted for the master branch but it was merged into the 2.2 branch instead (closes #8227).
