random.h (discrete_distribution<>::param_type): Disable move operations.

2010-10-12  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/bits/random.h (discrete_distribution<>::param_type):
	Disable move operations.
	(piecewise_constant_distribution<>::param_type): Likewise.
	(piecewise_linear_distribution<>::param_type): Likewise.

	* include/bits/random.h (discrete_distribution<>::param_type::
	param_type()): Simplify, don't use _M_initialize.
	(piecewise_constant_distribution<>::param_type::param_type()):
	Likewise.
	(piecewise_linear_distribution<>::param_type::param_type()):
	Likewise.
