A "make distclean" is not supported. So, it makes no sense to have pure
"make distclean" related stuff in the Makefile.am.

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

A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.

Remove BSP-specific defaults for RTEMS_BSP_CLEANUP_OPTIONS to simplify

BSP_PRESS_KEY_FOR_RESET=0

Change the testsuite configuration files to hold state information about
a test. The states are:
exclude - Do not build the test
expected-fail - The test is expected to fail
indeterminate - The test may pass or may fail
A message is printed just after the test's BEGIN message to indicate
there is a special state for the test. No state message means the test
is expected to pass.
This support requires tests are correctly written to the use standard
support to begin and end a test.

Notepads where a feature of RTEMS' tasks that simply functioned in
the same way as POSIX keys or threaded local storage (TLS). They were
introduced well before per task variables, which are also deprecated,
and were barely used in favor of their POSIX alternatives.
In addition to their scarce usage, Notepads took up unnecessary memory.
For each task:
- 16 32-bit integers were allocated.
- A total of 64 bytes per task per thread.
This is especially critical in low memory and safety-critical applications.
They are also defined as uint32_t, and therefore are not guaranteed to
hold a pointer.
Lastly, they are not portable solutions for SMP and uniprocessor systems,
like POSIX keys and TLS.

This was done by the following script run from libbsp:
find * -name bsp.h | xargs -e grep -l "#ifndef.*_BSP_H" | while read b
do
echo $b
cpu=`echo $b | cut -d'/' -f1 | tr '[:lower:]' '[:upper:]' `
bsp=`echo $b | cut -d'/' -f2 | tr '[:lower:]' '[:upper:]' `
g="LIBBSP_${cpu}_${bsp}_BSP_H"
# echo $g
sed -e "s/ifndef _BSP_H/ifndef ${g}/" \
-e "s/define _BSP_H/define ${g}/" \
-i $b

The first pass at building these was without networking enabled.
This pass addresses that plus accounts for some new BSPs which
needed testsuite.tcfg files and BSPs which could not link tests
which had been added since the first pass.

This is necessary to add tests that use the cache manager. For example
to get better estimates of worst-case timings.
