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.

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.

18129480ae Rename $type subnode to $flags
Type makes it sound like a type-hint, and on a number of other nodes
$type is used for exactly that. Use $flags to hold modifiers instead.

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?

437890d386 PHP 7: Short destructuring syntax
Potentially the pretty printer should force use of [] in assignment
context, instead of relying on the existance of the right attribute.

7eac2cfd8b 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.

a0c216bf4b Add dumpComments option to NodeDumper
Adding this as an option to avoid breaking people's tests.

Some of the test results show pretty clearly that we are incorrectly
assigning the same comment multiple times for nested nodes (mentioned
in #36).

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.
