MDL-41451 - Large forms are truncated by max_input_vars

By parsing php://input in chunks, we can bypass max_input_vars for
forms which do not use the "multipart/form-data" enctype.  This can
be (and is) safely skipped if there are fewer than max_input_vars
fields submitted as part of $_POST.
MDL-41451 - formslib: use create_function instead of inline function

As per MDL-39432, closure-style inline functions can result in fatal
errors when using eAccelerator and thus should be avoided.
