Reduced kernel size by 512KB by moving private buffer into cstart() function. Replaced assertions with erroneous return values. Removed assertions relating to isuserp(rp), since all processes should become user processes; system processes are now treated similar to other processes.

/* Function prototypes for the system library. The implementation is contained

|
* by doing a system call. System calls are transformed into request messages
|
|
* to the SYS task that is responsible for handling the call. By convention, a
|
|
* sys_call() is transformed into a message with type SYS_CALL that is handled
|
|
* in a function named do_call().
