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.

- *
- * From the highest level viewpoint, there are 2 types of context to save.
- *
- *    -# Interrupt registers to save
- *    -# Task level registers to save
- *
- * Since RTEMS handles integer and floating point contexts separately, this
- * means we have the following 3 context items:
- *
- *    -# task level context stuff::  Context_Control
- *    -# floating point task stuff:: Context_Control_fp
- *    -# special interrupt level context :: CPU_Interrupt_frame
- *
- * On some processors, it is cost-effective to save only the callee
- * preserved registers during a task context switch.  This means
- * that the ISR code needs to save those registers which do not
- * persist across function calls.  It is not mandatory to make this
- * distinctions between the caller/callee saves registers for the
- * purpose of minimizing context saved during task switch and on interrupts.
- * If the cost of saving extra registers is minimal, simplicity is the
- * choice.  Save the same context on interrupt entry as for tasks in
- * this case.
- *
- * Additionally, if gdb is to be made aware of RTEMS tasks for this CPU, then
- * care should be used in designing the context area.
- *
- * On some CPUs with hardware floating point support, the Context_Control_fp
- * structure will not be used or it simply consist of an array of a
- * fixed number of bytes.   This is done when the floating point context
- * is dumped by a "FP save context" type instruction and the format
- * is not really defined by the CPU.  In this case, there is no need
- * to figure out the exact format -- only the size.  Of course, although
- * this is enough information for RTEMS, it is probably not enough for
- * a debugger such as gdb.  But that is another problem.
