The opaque pipe object id type is now a pointer to the associated pipe structure, rather than an index into the microkernel's array of pipe structures. This change is a pre-requisite to support for private pipes, which are defined in source code. This also moves the required struct into more visible headers such that private pipes can be declared. Renaming the struct is also being done to conform to naming convention for private kernel objects. Since a couple structs have to be moved anyway, so do the moving and renaming here too (contrary to what have been done in the past, with separated patches).
