Adjust various build files. Remove automatic generation of the
c/src/lib/libbsp/*/acinclude.m4 files from bootstrap script.

This AC_CONFIG_SRCDIR() is just a sanity check in this insane build
system. Since all content of
c/src/lib/libbsp/@RTEMS_CPU@/@RTEMS_BSP_FAMILY@ is bound to be moved it
makes no sense to keep it.

The subdir-objects do not work currently due to BSP sources in bsps and

This option silences warning with automake-1.16.1 allowing us to
upgrade to that version.
This change has been tested with automake-1.12.6 and automake-1.16.1.
It seems version 1.16.1 configures slower than 1.12.6 for the same
source and BSP. The newer versions is 6 second slower.
Close #3387.

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
the BSP configuration and documentation. Change defaults to:
BSP_PRESS_KEY_FOR_RESET=0
BSP_RESET_BOARD_AT_EXIT=1
BSP_PRINT_EXCEPTION_CONTEXT=1
