	PR 1906/cpukit
	* sapi/Makefile.am, sapi/preinstall.am, sapi/include/confdefs.h,
	score/Makefile.am, score/preinstall.am: Add the CBS (Constant
	Bandwidth Server) scheduler. This is a complex scheduling policy
	built atop of the EDF scheduler. Unlike other schedulers, this one
	provides a user API and handles not only deadlines of tasks but also
	claimed budget per period. The main aim of the scheduler is isolation
	of tasks so that each task is guaranteed to meet all deadlines
	regardless of how other tasks behave.
	* sapi/include/rtems/cbs.h, sapi/inline/rtems/cbs.inl,
	score/include/rtems/score/schedulercbs.h, score/src/schedulercbs.c,
	score/src/schedulercbsattachthread.c,
	score/src/schedulercbscleanup.c,
	score/src/schedulercbscreateserver.c,
	score/src/schedulercbsdestroyserver.c,
	score/src/schedulercbsdetachthread.c,
	score/src/schedulercbsgetapprovedbudget.c,
	score/src/schedulercbsgetexecutiontime.c,
	score/src/schedulercbsgetparameters.c,
	score/src/schedulercbsgetremainingbudget.c,
	score/src/schedulercbsgetserverid.c,
	score/src/schedulercbsreleasejob.c,
	score/src/schedulercbssetparameters.c,
	score/src/schedulercbsunblock.c: New files.
