John Baldwin bd78cece5d Change the kernel's ucred API as follows: ... - crhold() returns a reference to the ucred whose refcount it bumps. - crcopy() now simply copies the credentials from one credential to another and has no return value. - a new crshared() primitive is added which returns true if a ucred's refcount is > 1 and false (0) otherwise.		2001-10-11 23:38:17 +00:00
