 *  ABSTRACT:
 *
 *	TCB-related definitions.
 *
 *  AUTHORS:
 *
 *	Dave Butenhof
 *
 *  CREATION DATE:
 *
 *	24 July 1989
 *
 *  MODIFICATION HISTORY:
 *
 *	001	Dave Butenhof	14 August 1989
 *		Extract context list into separate typedef for casts.
 *	002	Dave Butenhof	15 August 1989
 *		Add type field to object structure.
 *	003	Dave Butenhof	21 August 1989
 *		Add pointer to first stack descriptor for thread.
 *	004	Dave Butenhof	24 August 1989
 *		Modify TCB to use queues instead of lists
 *	005	Webb Scales	26 August 1989
 *		Change from jmp_buf context to private context type
 *	006	Dave Butenhof	29 August 1989
 *		Remove #include of cma_stack.h, since we don't need it any
 *		more.  Define context buffer locally to minimize dependencies
 *		and risk of circularities.
 *	007	Dave Butenhof	31 August 1989
 *		Rename cv field to term_cv.
 *	008	Dave Butenhof	14 September 1989
 *		Add alert state field to TCB.
 *	009	Hans Oser	22 Septemper 1989
 *		Add pc and psl field to TCB.
 *	010	Webb Scales	26 September 1989
 *		Change position of FP field in context buffer.
 *	011	Dave Butenhof	29 September 1989
 *		Add initial_test field to TCB (TCB creation will copy from
 *		attributes object so TCB is independent of changes to attr.
 *		obj between creation and execution).
 *	012	Dave Butenhof	11 October 1989
 *		Convert to use internal mutex operations.
 *	013	Dave Butenhof	16 October 1989
 *		Change TCB fields for Hans...
 *	014	Hans Oser	20 October 1989
 *		Add TCB fields for ultrix "select"
 *	015	Webb Scales	23 October 1989
 *		Changed "..._PSL" to "..._ps"
 *	016	Dave Butenhof	27 October 1989
 *		Add TCB field so alert can find condition variable to
 *		broadcast on (simplest way to break through wait).
 *	017	Dave Butenhof	1 November 1989
 *		Add backpointer for mutex.
 *	018	Dave Butenhof	16 November 1989
 *		Define tcb_time structure here to avoid circular
 *		dependencies.
 *	019	Webb Scales	18 November 1989
 *		Make thread context structure(s) host dependent
 *	020	Dave Butenhof	22 November 1989
 *		Make forward decl for semaphore structure to resolve circular
 *		references.
 *	021	Dave Butenhof	30 November 1989
 *		Add field for scheduling policy (not implemented yet).
 *	022	Dave Butenhof	4 December 1989
 *		Remove all the type definitions to cma_tcb_def.h to try to
 *		break circular dependencies.
 *	023	Paul Curtin	8 April 1991
 *		Added externs for use with quick kill
 *	024	Paul Curtin	24 May 1991
 *		Added a prototype for cma__reinit_tcb
