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.

+/**
+ *  \file
+ *
+ *  \par Purpose
+ *
+ *  Standard output methods for reporting debug information, warnings and
+ *  errors, which can be easily be turned on/off.
+ *
+ *  \par Usage
+ *  -# Initialize the DBGU using TRACE_CONFIGURE() if you intend to eventually
+ *     disable ALL traces; otherwise use DBGU_Configure().
+ *  -# Uses the TRACE_DEBUG(), TRACE_INFO(), TRACE_WARNING(), TRACE_ERROR()
+ *     TRACE_FATAL() macros to output traces throughout the program.
+ *  -# Each type of trace has a level : Debug 5, Info 4, Warning 3, Error 2
+ *     and Fatal 1. Disable a group of traces by changing the value of
+ *     TRACE_LEVEL during compilation; traces with a level bigger than TRACE_LEVEL
+ *     are not generated. To generate no trace, use the reserved value 0.
+ *  -# Trace disabling can be static or dynamic. If dynamic disabling is selected
+ *     the trace level can be modified in runtime. If static disabling is selected
+ *     the disabled traces are not compiled.
+ *
+ *  \par traceLevels Trace level description
+ *  -# TRACE_DEBUG (5): Traces whose only purpose is for debugging the program,
+ *     and which do not produce meaningful information otherwise.
+ *  -# TRACE_INFO (4): Informational trace about the program execution. Should
+ *     enable the user to see the execution flow.
+ *  -# TRACE_WARNING (3): Indicates that a minor error has happened. In most case
+ *     it can be discarded safely; it may even be expected.
+ *  -# TRACE_ERROR (2): Indicates an error which may not stop the program execution,
+ *     but which indicates there is a problem with the code.
+ *  -# TRACE_FATAL (1): Indicates a major error which prevents the program from going
+ *     any further.
