853e73fb8e Reduce struct size, on 64-bit by 8 bytes each 
Note, the max modifiable flag value is currently 1<<5, there is still
some space. ATM it looks unlikely, but should more flags need to be
added, the types will need to be reconsidered.

49d9b3013f Move cwd_state and path related routines to size_t 
Having `int` there is no real profit in the size or speed, while unsigned
improves security and overall integration. ZPP supplied strings can
be then accepted directly and structs can be still handled with smaller
unsigned types for size reasons, which is safe. Yet some related places
are to go.

basic move tsrm_realpath_r to size_t

fix conditions and sync with affected places

touch ocurrences of php_sys_readlink usage

follow up on phar path handling

remove duplicated check

move zend_resolve_path and related pieces to size_t

touch yet resolve path related places

remove cast

missing pieces

missing piece

yet cleanups for php_sys_readlink for ssize_t

fix wrong return

e08c0ed8ce Bug #74815 crash with a combination of INI entries at startup 
TS related VCWD routines depend on CWD. Thus, a premature CWD
deactivation renders the VCWD layer unusable. Same issue seems to
persist in versions < 7.2, just that the code path is actually unused so
the issue didn't show up. Still might make sense to backport this into
lower branches.

ace9fe5317 Improved new Zend Parameter Parsing API to avoid useless dereferences. 
This derefernce made sense only for explicit paramter passing by reference, but this feature was removed in PHP-7.
The improvement is 100% backward compatible, only few "tricky" functions may be affected (e.g. extract and usort).
