This function will undo all operations on a TCB performed by task_init() and release the TCB by calling kmm_free(). This is intended primarily to support error recovery operations after a successful call to task_init() such was when a subsequent call to task_activate fails.

PR-1134 Add typedef for max_align_t

PR-1141 Handle custom stack allocations

sched_releasetcb() will normally free the stack allocated for a task. However, a task with a custom, user-managed stack may be created using nxtask_init() followed by nxtask_activate(). If such a custom stack is used then it must not be freed in this manner or a crash will most likely result.

This change adds a flag call TCB_FLAG_CUSTOM_STACK that may be passed in the the pre-allocated TCB to nxtask_init(). This flag is not used internally anywhere in the OS except that if set, it will prevent sched_releasetcb() from attempting to free that custom stack.
