f7d484aa0e Fix handling of empty input

06c7ab51b7 Drop Lexer::getTokens() method 
This doesn't make a lot of sense now that Lexer::tokenize() returns
the tokens.

The tokens for the last parse should be fetched via
Parser::getTokens() instead.

502b090900 Add property types 
Types omitted in two places where we violate them currently:
Namespace_::$stmts can be null during parsing, and Enum_::$scalarType
can be a complex type for invalid programs.

ba851243f4 Replace startLexing() with tokenize() 
For now Lexer::getTokens() still exists, but should probably be
removed.

4b497045e0 Move attribute handling into parser 
The Lexer now only provides the tokens to the parser, while the
parser is responsible for determining which attributes are placed
on notes. This only needs to be done when the attributes are
actually needed, rather than for all tokens.

This removes the usedAttributes lexer option (and lexer options
entirely). The attributes are now enabled unconditionally. They
have less overhead now, and the need to explicitly enable them for
some use cases (e.g. formatting-preserving printing) doesn't seem
like a good tradeoff anymore.

There are some additional changes to the Lexer interface that
should be done after this, and the docs / upgrading guide haven't
been adjusted yet.

dd63ddbc24 Add php-cs-fixer config and reformat 
The formatting in this project has become something of a mess,
because it changed over time. Add a CS fixer config and reformat
to the desired style, which is PSR-12, but with sane brace placement.

Add support for new PHP 8.1 modifiers (#796) 
Implement support for readonly properties (https://wiki.php.net/rfc/readonly_properties_v2) and
final class contstants (https://wiki.php.net/rfc/final_class_const).

c758510a37 Add support for PHP 8.1 
With the introduction of intersection types, PHP now lexes the
token '&' either as T_AMPERSAND_(NOT_)FOLLOWED_BY_VAR_OR_VARARG.
This completely breaks parsing of any code containing '&'.

Fix this by canonicalizing to the new token format (unconditionally,
independent of emulation) and adjusting the parser to use the two
new tokens.

This doesn't add actual support for intersection types yet.

b9b45dd2bc Insert T_BAD_CHARACTER tokens for missing characters 
The token stream should cover all characters in the original code,
insert a dummy token for missing illegal characters. We should
really be doing this in token_get_all() as well.
