be96cb4345 sparc: Simplify trap table initialization
Move _ISR_Handler() to a separate file since it is now only used if a handler
is installed by _CPU_ISR_install_raw_handler().

Statically initialize the traps for external interrupts to use the new
_SPARC_Interrupt_trap() which directly dispatches the interrupt handlers
installed by rtems_interrupt_handler_install() via the BSP-provided
_SPARC_Interrupt_dispatch().

Since the trap table is now fully statically initialized, there is no longer a
dependency on the Cache Manager in the default configuration.

Update #4458.

d73e657e06 sparc: More reliable bad trap handling
Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap()
for all unexpected traps.  This enables a proper RTEMS fatal error handling
right from the start.  Do not rely on the stack and register settings which
caused an unexpected trap.  Use the ISR stack of the processor to do the fatal
error handling.  Save the full context which caused the trap.  Fatal error
handler may use it for error logging.

Unify the _CPU_Exception_frame_print() implementations and move it to cpukit.

Update #4459.

4cf93658ef bsps: Rework cache manager implementation
The previous cache manager support used a single souce file
(cache_manager.c) which included an implementation header (cache_.h).
This required the use of specialized include paths to find the right
header file.  Change this to include a generic implementation header
(cacheimpl.h) in specialized source files.

Use the following directories and files:

* bsps/shared/cache

* bsps/@RTEMS_CPU@/shared/cache

* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILY/start/cache.c

Update #3285.
