- all macros in consts.h that depend on NR_TASKS replaced by a FP_BLOCKED_ON_* - fp_suspended removed and replaced by fp_blocked_on. Testing whether a process is supended is qeual to testing whether fp_blocked_on is FP_BLOCKED_ON_NONE or not - fp_task is valid only if fp_blocked_on == FP_BLOCKED_ON_OTHER - no need of special values that do not colide with valid and special endpoints since they are not used as endpoints anymore - suspend only takes FP_BLOCKED_ON_* values not endpoints anymore - suspend(task) replaced by wait_for(task) which sets fp_task so we remember who are we waiting for and suspend sets fp_blocked_on to FP_BLOCKED_ON_OTHER to signal that we are waiting for some other process - some functions should take endpoint_t instead of int, fixed
