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)

Remove need to pass error level

Enable throwing custom exceptions from errors

Use ZSTR_ API to access zend_string elements (this is just renaming without semantick changes).

Use the new 'ZSTR' macros in the rest of the code.

Does not change anything to the generated code (thanks to compat macros) but cleaner.

Improve zend_string API

Add missing methods

show more ...

Avoid zval duplication in ZVAL_ZVAL() macro (it was necessary only in few places).
Switch from ZVAL_ZVAL() to simpler macros where possible (it makes sense to review remaining places)

Also unreserve T_CLASS

Rebase Joe's anon classes implementation

Drop ??? for AST_ZNODE in ast pretty printer

Add "yield from" support to ast pretty printer

Convert fatal errors into EngineExceptions
Make zval_update_constant_ex(), zval_update_constant(), zend_update_class_constants() and zend_ast_evaluate() return SUCCESS or FAILURE.

Use zend_error_noreturn() for fatal errors

Unused var

Implemented AST pretty-printer

Implement return types

RFC is documented here: https://wiki.php.net/rfc/return_types

Provide compiler hook for altering the AST pre-compilation.

bump year

bump year

Micro optimaztion (yeah, I know compiler supposed to do that)

first shot remove TSRMLS_* things

bring back all the TSRMLS_FETCH() stuff

for better comparability with the mainstream

cleanup TSRMLS_FETCH

fix unsigned negation

Use zval_ptr_dtor_nogc to destroy literals

Also move the definition of zval_ptr_dtor_nogc to zend_variables.h
(from zend_execute.h/.c) as it's used in a few places.

fix C89 compat
