a46b309975 Move constants into NodeTraverser class 
Not that the interface makes much sense anyway, but these are
implementation details of a specific traverser.

f99a96e0a2 Introduce ErrorHandler 
Add ErrorHandler interface, as well as ErrorHandler\Throwing
and ErrorHandler\Collecting. The error handler is passed to
Parser::parse(). This supersedes the throwOnError option.

NameResolver now accepts an ErrorHandler in the ctor.

90834bff8e Add namespacedName attribute on runtime-resolved names

caa5c0cc76 Graceful handling for "special" errors 
Nearly all special errors are now handled gracefully, i.e. the
parser will be able to continue after encountering them. In some
cases the associated error range has been improved using the new
end attribute stack.

To achieve this the error handling code has been moved out of the
node constructors and into special methods in the parser.

c79ea6d1d3 Support recovery from lexer errors 
Lexer::startLexing() no longer throws, instead errors can be fetched
using Lexer::getErrors().

Lexer errors now also contain full line and position information.

17d1e738fa Don't use ~__EMU sequences in emulative lexer 
These were necessary back in the day when we had to emulate some
complex functionality such as nowdoc strings. Now we can simply
directly translate certain token sequences.

The motivation for this change is to avoid preprocessing of the source
code, which would complicate offset-aware error handling inside the
lexer as offsets would no longer be correct.

977cbab8e7 Decrement errorState when recovering from -> error 
It's likely that an error after -> will trigger another one due to
missing semicolon without shifting a single token. We prevent an
immediate failure in this case by manually setting errorState to 2,
which will suppress the duplicate error message, but allow error
recovery.

574665b45b PHP 7.1: list() with keys 
Expr\List will now contain ArrayItems instead of plain variables.
I'm reusing ArrayItem, because code handling list() must also handle
arrays, and this allows both to go through the same code path.

This also renames Expr\List->vars to ->items.

TODO: Should Expr\List be dropped in favor of Expr\Array with an
extra flag?

588e6a4d4c 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.

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.

648800f07f Increase float pretty printing precision 
This removes the reliance on the "precision" ini setting.
Furthermore the default of precision=14 is not sufficient.

3b7d8e8b5d Enable basic error recovery 
Adding only a single recovery rule for now.

The API is now:
 * throwOnError parser option must be disabled.
 * List of Errors is available through $parser->getErrors(). This
   method is available either way.
 * If no recovery is possible $parser->parse() will return null.
   (Obviously only if throwOnError is disabled).
