* Global function for chmodding directories and files for internal use

* The function determines owner and group from common.php file and sets the same to the provided file. Permissions are mapped to the group, user always has rw(x) permission.
* The function uses bit fields to build the permissions.
* The function sets the appropiate execute bit on directories.
*
* Supported constants representing bit fields are:
*
* CHMOD_ALL - all permissions (7)
* CHMOD_READ - read permission (4)
* CHMOD_WRITE - write permission (2)
* CHMOD_EXECUTE - execute permission (1)
*
* NOTE: The function uses POSIX extension and fileowner()/filegroup() functions. If any of them is disabled, this function tries to build proper permissions, by calling is_readable() and is_writable() functions.
