Add support for negative interpolated offsets

A late addition to PHP 7.1 which I missed.

Add php-parse --with-positions

To invoke NodeDumper in dumpPositions mode

Parse 0 in "$a[0]" as LNumber (#325)

Add UPGRADE note about NameResolver changes

Release PHP-Parser 3.0.2

Fix pretty-printing of nullable types

NameResolver - resolve Name in NullableType

Add NullableType to types of properties/args that offer it (#323)

Release PHP-Parser 3.0.1

Wrap List_ in ArrayItem

This was correctly done for the 'key'=>list() form, but not for
unkeyed nested lists.

Release PHP-Parser 3.0

Cleanup imports

Thanks PhpStorm :)

Fix attribute assignment for Error nodes

Support !!positions parser test mode

And use it for the group use prefix position test that was
previously implemented as a separate test.

Add support for dumping positions in NodeDumper

Support recovery from Foo::

Support recovery from free-standing $

Support recovery for new without class name

Release PHP-Parser 3.0.0-beta2

Update docs

Mark Name::$parts as deprecated

Represent empty Name::slice() using null

Instead of a Name([]) dummy value, that is invalid in other
contexts.

Explicitly support Name copy construction

It already worked beforehand by accident ... make clear it's
actually supported.

Remove Name::append() and Name::prepend()
