Remove make preinstall

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.

Update #3254.

- * @defgroup bsp_interrupt BSP Interrupt Support
- *
- * @ingroup bsp_shared
- *
- * @brief Generic BSP Interrupt Support
- *
- * The BSP interrupt support manages a sequence of interrupt vector numbers
- * ranging from @ref BSP_INTERRUPT_VECTOR_MIN to @ref BSP_INTERRUPT_VECTOR_MAX
- * including the end points.  It provides methods to
- * @ref bsp_interrupt_handler_install() "install",
- * @ref bsp_interrupt_handler_remove() "remove" and
- * @ref bsp_interrupt_handler_dispatch() "dispatch" interrupt handlers for each
- * vector number.  It implements parts of the RTEMS interrupt manager.
- *
- * The entry points to a list of interrupt handlers are stored in a table
- * (= handler table).
- *
- * You have to configure the BSP interrupt support in the <bsp/irq.h> file
- * for each BSP.  For a minimum configuration you have to provide
- * @ref BSP_INTERRUPT_VECTOR_MIN and @ref BSP_INTERRUPT_VECTOR_MAX.
- *
- * For boards with small memory requirements you can define
- * @ref BSP_INTERRUPT_USE_INDEX_TABLE.  With an enabled index table the handler
- * table will be accessed via a small index table.  You can define the size of
- * the handler table with @ref BSP_INTERRUPT_HANDLER_TABLE_SIZE.
- *
- * Normally new list entries are allocated from the heap.  You may define
- * @ref BSP_INTERRUPT_NO_HEAP_USAGE, if you do not want to use the heap.  For
- * this option you have to define @ref BSP_INTERRUPT_USE_INDEX_TABLE as well.
- *
- * You have to provide some special routines in your BSP (follow the links for
- * the details):
- * - bsp_interrupt_facility_initialize()
- * - bsp_interrupt_vector_enable()
- * - bsp_interrupt_vector_disable()
- * - bsp_interrupt_handler_default()
- *
- * The following now deprecated functions are provided for backward
- * compatibility:
- * - BSP_get_current_rtems_irq_handler()
- * - BSP_install_rtems_irq_handler()
- * - BSP_install_rtems_shared_irq_handler()
- * - BSP_remove_rtems_irq_handler()
- * - BSP_rtems_irq_mngt_set()
