Fixed the context parameter on copy() to actually have an effect

# After looking at the logs, Jani did a bad merge into 5.3, so that 
# the context parameter sent to copy() actually isn't used at all. This 
# relatively simple patch fixes that for trunk.
#
# See FR #42965

# internals:
# This changes the php_copy_*() decls to contain an additional parameter for stream contexts
