Raise compiler warning on octal overflow

Addresses https://bugs.php.net/bug.php?id=71994

Eliminated checks for (func->op_array.fn_flags & ZEND_ACC_GENERATOR) in fast path of DO_FCALL* handlers.
This slightly improves calls to regular function and method calls in cost of a bit slower

Eliminated checks for (func->op_array.fn_flags & ZEND_ACC_GENERATOR) in fast path of DO_FCALL* handlers.
This slightly improves calls to regular function and method calls in cost of a bit slower generator initialization.
Separate call frame for generators, allocated on heap, now created by ZEND_GENERATOR_CREATE instruction.

Revert "Refactor zval cleanup into single function"

This reverts commit bac6fdb0c52c924e726c5a78de8858bf27b6586b.

Refactor zval cleanup into single function

Also use zval_ptr_dtor_nogc() everywhere in Zend in favor of zval_dtor()

Don't return T_ERROR from token_get_all()

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.

Fix bug #69430

Don't throw from token_get_all() unless TOKEN_PARSE is used. Errors
are reported as T_ERROR tokens.

Switch code on thrown TypeError and ParseError to 0, update related tests

Replace references to PHP_WIN32 and TSRM_WIN32 with ZEND_WIN32 in Zend/, this also fixes 1 instance of where fflush(stderr) was misplaced (zend_extensions.c)

Switch position of ce in exception ce variable names

Cleanup exception ce API

Removed recently added functions to get Error ce's and marked the old functions
fetching default_exception_ce and error_exception_ce as deprecated.

Remodel exceptions based on Throwable interface

Added Throwable interface that exceptions must
implement in order to be thrown. BaseException
was removed, EngineException renamed to

Remodel exceptions based on Throwable interface

Added Throwable interface that exceptions must
implement in order to be thrown. BaseException
was removed, EngineException renamed to
Error, and TypeException and ParseException
renamed to TypeError and ParseError. Exception
and Error no longer extend a common base
class, rather they both implement the Throwable
interface.

ext tokenizer port + cleanup unused lexer states

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.

implement context sensitive language with lexical feedback

The implementation has no regression risks, has an even smaller footprint
compared to the previous attempt involving a pure lexical approach, is higly
predictable and higly configurable.

To turn a word semi-reserved you only need to edit the "SEMI_RESERVED" parser rule,
it's an inclusive list of all the words that should be matched as T_STRING on specific contexts.
Example:

```
method_modifiers function returns_ref indentifier '(' parameter_list ')' ...
```

instead of:

```
method_modifiers function returns_ref T_STRING '(' parameter_list ')' ...
```

Add line_start/end info to main op_array

Move more stuff to file_context

Introduce helper macro FC(x) for CG(file_context).x.

end_compilation() now handled by file_context_end().

Fixed bug #69388

Renamed compiler_context to oparray_context. Introduced per-file
file_context. Moved import tables into the file_context.

context_stack no longer exists, instead keeping backups of contexts
on C stack. Same for file contexts.

TODO: Move more things out of CG into file_context. There should be
a number of other things that we should not try to reuse in nested
compilations.

Use zend_error_noreturn() for fatal errors

Optimize zend_string_realloc() add more specialized versions zend_string_extend() and zend_string_truncate()

Support ParseException for require etc
