PHP 7.1: Class constant visibility support

Escape all low control characters in strings

Switch Exit kind attribute to flag

To be consistent with everything else.

Add string kinds and doc string labels

Scalar\String_ and Scalar\Encapsed now have an additional "kind"
attribute, which may be one of:

* String_::KIND_SINGLE_QUOTED
* Str

Add string kinds and doc string labels

Scalar\String_ and Scalar\Encapsed now have an additional "kind"
attribute, which may be one of:

* String_::KIND_SINGLE_QUOTED
* String_::KIND_DOUBLE_QUOTED
* String_::KIND_NOWDOC
* String_::KIND_HEREDOC

Additionally, if the string kind is one of the latter two, an
attribute "docLabel" is provided, which contains the doc string
label (STR in <<<STR) that was originally used.

The pretty printer will try to take the original kind of the string,
as well as the used doc string label into account.

Add "kind" attribute to Stmt\Exit_

Attribute specifies whether this is a "die" or an "exit" and the
pretty printer behaves accordingly.

Introduce Nop statement to collect dangling comments

A Nop statement will be inserted into statement lists if there are
any trailing comments in the list (which would otherwise not be
associated with any node).

The pretty printer output currently still contains a superfluous
newline.

Distinguish declare(); and declare(){}

It makes semantic difference and the latter form is actually
forbidden for strict_types.

This sets Declare->stmts to null for the body-les

Introduce Scalar\EncapsedStringPart

Add option for short array syntax in pretty printer

Fix pretty printing of const derefs for 5.x

(FOO)[0] is only supported on 7.x

Support UVS in pretty printer

Try to generate interoperable code where possible (but not
everything can be expressed in PHP 5).

Support mixed group use declarations

Add partial group use support

Supported via Stmt\GroupUse which has Name $prefix in addition to
the usual.

Still missing: Mixed group uses.

Try .17G print if .16G is not enough

This should be enough for all cases, because: A double has 53 bits
of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10)
= 15.95 d

Try .17G print if .16G is not enough

This should be enough for all cases, because: A double has 53 bits
of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10)
= 15.95 decimal digits. However the leading decimal digit may encode
less than the usual 3.32 bits, which will push this over the edge to
requiring 17 decimal digits.

Increase float pretty printing precision

This removes the reliance on the "precision" ini setting.
Furthermore the default of precision=14 is not sufficient.

Add support for anonymous classes

Has not landed upstream yet, but syntax is unlikely to change.

Fix "print" pretty-printing

Precedence was previously ignored.

Add support for "yield from"

Rename Cast\Object as well

As it will very likely be soft-reserved in PHP 7.

Old alias is still available, as usual.

Rename nodes for compat with PHP 7

The old names will still be available on PHP 5.x.

Add support for spaceship operator (<=>) [PHP 7]

Added as Expr\BinaryOp\Spaceship.

Add support for null coalesce operator (??) [PHP 7]

Added as Expr\BinaryOp\Coalesce.

Drop whitespace after ... varargs collection

Also drop an obsolete pretty printer test.
