Rename _Scheduler_Set_idle_thread() in _Scheduler_Node_set_idle_user() and move
it to <rtems/score/schedulernodeimpl.h>.

In SMP configurations, on 64-bit architectures use plain atomic
operations to set/get the priority value of a scheduler node. On 32-bit
architectures use an ISR lock. Using a sequence lock has no real
benefit since it uses atomic read-modify-write operations for both the
read and the write lock. Simply use a ticket lock instead so that only
one SMP synchronization primitive is used for everything.

Use the new Priority_Group_order enum instead of a boolean to indicated if a
priority should be inserted as the first or last node into its priority group.
This makes the code more expressive. It is also a bit more efficient since a
branch in _Scheduler_Node_set_priority() is avoided and a simple bitwise or
operation can be used.

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.
