sys/tree.h: Red child with black sibling rotations
Add specialized rotations RB_RED_ROTATE_LEFT() and RB_RED_ROTATE_RIGHT() which
may be used if we rotate a red child which has a black sibling. Such a red
node must have at least two child nodes so that the following red-black tree
invariant is fulfilled:
Every path from a given node to any of its descendant NULL nodes goes through
the same number of black nodes.

From the Dhrystone RATIONALE:
o No procedure merging
Although Dhrystone contains some very short procedures where execution would
benefit from procedure merging (inlining, macro expansion of procedures),
procedure merging is not to be used. The reason is that the percentage of
procedure and function calls is part of the "Dhrystone distribution" of
statements contained in [1]. This restriction does not hold for the string
functions of the C version since ANSI C allows an implementation to use
inline code for these functions.
Close#5058.
Closes#5055
## Summary
add rtems_counting_semaphore_wait_timed_ticks and rtems_counting_semaphore_try_wait for self-contained object counting semaphore.
1. rtems_counting_semaphore_wait_timed_ticks(rtems_counting_semaphore \*counting_semaphore,uint32_t ticks)
2. rtems_counting_semaphore_try_wait(rtems_counting_semaphore \*counting_semaphore)
close issue #5055.

This switches the XQspiPsu NOR driver layer to use the RTEMS event
system so that waits for interrupt-based data transfers can time out
instead of waiting indefinitely. It is sometimes possible for either the
controller or the NOR chip to fail to issue a transfer completion event
and recovery is preferable to a hang.
Added field to the aio control block to track when a result is retrieved
and modified code accordingly.
Updated documentation for aio_return() and aio_error().
Updated test psxaio01 to make it compatible with specifications.
Closes#5039
Set/clear SCTLR[I] on all online processors. Do not enable/disable the
L2C-310 cache in the instruction cache enable/disable since it is a
unified cache.
On some targets or configurations, the data cache cannot be disabled.
The data cache may be necessary to provide atomic operations. In SMP
configurations, the data cache may be required to ensure data coherency.
Close#5050.
If the RTEMS_INTERRUPT_LOCK_NEEDS_OBJECT define has a non-zero value,
then the interrupt lock operations require an object of type
rtems_interrupt_lock, otherwise no lock object is required.
This indication can be used to avoid the space overhead for lock objects
when they are not needed. In this case, the lock operations will not
use a lock objects parameter.
Update #4957 and #5038.
This adds error reporting for ZynqMP including L1 and L2 cache, on-chip
memory (OCM) error correcting code (ECC), and DDR ECC. OCM ECC supports
fault injection from within RTEMS. DDR ECC technically supports fault
injection as well, but requires that the program injecting faults
operate exclusively outside of DDR. The AArch64 port is not currently
capable of operating exclusively in OCM due to size constraints and
would need to be booted via JTAG or via a non-relocating u-boot to
accomplish this.
When starting multitasking there is a chance an interrupt could be fired
while rsp is still pointing to the ISR stack area if we load rflags
before rsp on "_CPU_Context_restore"
This test was broken by b031cf2b19 since
it expects the macros to evaluate to an empty string for non-SMP builds.
This updates the check for the new content.
