719ca71d4a 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-less case.

8b64195cf2 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.

ac6f221c50 Better prededence and associativity handling in pretty printer 
Previously the pretty printer added unnecessary and odd-looking parentheses
when several operators with the same precedence were chained:

    'a' . 'b' . 'c' . 'd' . 'e'
    // was printed as
    'a' . ('b' . ('c' . ('d' . 'e')))

Another issue reported as part of #39 was that assignments inside closures
were wrapped in parentheses:

    function() {
        $a = $b;
    }
    // was printed as
    function() {
        ($a = $b);
    }

This was caused by the automatic precedence handling, which just regarded
the closure as an ordinal nested expression.

With the new system the $predenceMap of PrettyPrinterAbstract contains both
precedence and associativity and there is a new method pPrec() which prints
a node taking precedence and associativity into account.

For simpler usage there are additional function pInfixOp(), pPrefixOp() and
pPostfixOp().

Prints not going through pPrec() do not have any precedence handling (fixing
the closure issue).

f8f1e17e41 Add support for list() in foreach (PHP 5.5) 
Example: foreach ($coords as list($x, $y)) { ... }

This change slightly breaks backwards compatability, as it changes the
node structure for the previously existing `list(...) = $foo` assignments.
Those no longer have a dedicated `AssignList` node; instead they are
parsed as a normal `Assign` node with a `List` as `var`. Similarly the
use in `foreach` will generate a `List` for `valueVar`.

e16513a0eb Fix parsing of new expressions in parenthesis 
The new dereferencing syntaxes (new Foo)->bar and (new Foo)['bar'] were
causing a shift/reduce conflict with the '(' expr ')' rule. When
(new Foo) was encountered (without dereference operators following) the
parser thus threw a parse error.

The fix simply adds a special '(' new_expr ')' rule to expr. This does not
remove the shift/reduce conflict itself, but makes it irrelevant.

This fixes issue #20.

db3181aff1 More test coverage and doc string parsing fixes 
The parser didn't account for the additional newline after the content of doc strings, which is left there by the tokenizer for some reason. Additoinally esacape sequences were parsed in nowdoc strings.

Additionally this contains some minor changes to the grammar: Some _list nonterminals were refactored to have the possible single elements in a reparate rule and only assemble those single elements. (This reduces duplication and gives better assignment of line number context.)
