* The ending label no longer has to be followed by a semicolon or
newline. Any non-label character is fine.
* The ending label may be indented. The indentation will be stripped
from all lines in the heredoc/nowdoc string.
Lexing of heredoc strings performs a scan-ahead to determine the
indentation of the ending label, so that the correct amount of
indentation can be removed when calculting the semantic values for
use by the parser. This makes the implementation quite a bit more
complicated than we would like :/
PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
Introduce an on_event_context passed to the on_event hook. Use this
context to pass along the token array. Previously this was stored
in a non-tls global :/
This fixes the following build issue on 160-CPU POWER8 machines
ext/tokenizer/tokenizer_data.c:28:34: fatal error: zend_language_parser.h: No such file or directory
#include <zend_language_parser.h>
It is fixed by introducing an explicit dependency on the header file.

This turned out to be rather inconvenient after all. Instead just
return the same output we did on PHP 5. If people want to have an
error, use TOKEN_PARSE.
we basically added a mechanism to store the token stream during parsing
and exposed the entire parser stack on the tokenizer extension through
an opt in flag: token_get_all($src, TOKEN_PARSE).
this change allows easy future language enhancements regarding context
aware parsing & scanning without further maintance on the tokenizer
extension while solves known inconsistencies "parseless" tokenizer
extension has when it handles `__halt_compiler()` presence.
Primarily to avoid getting fatal errors from token_get_all().
Implemented using a magic E_ERROR token, which the lexer emits to
force a parser failure.
