Created futimens.c and utimensat.c to add support for the POSIX
methods futimens() and utimensat().
utime() and utimes() are considered obsolote by POSIX, but RTEMS
will continue to support them.
Closes #4396

There was a race conditon in the reference counting of file descriptors
during a close() operation. After the call to the close handler, the
rtems_libio_free() function cleared the flags to zero. However, at this
point in time there may still exist some holders of the file descriptor.
With RTEMS_DEBUG enabled this could lead to failed assertions in
rtems_libio_iop_drop().
Change the code to use only atomic read-modify-write operations on the
rtems_libio_iop::flags.

The IO library used a POSIX key to store an optional POSIX user
environment pointer. This pulled in the POSIX keys support in every
application configuration. Add a user environment pointer to the thread
control block (TCB) instead. Applications which do not need the POSIX
user environment will just get an overhead of one pointer per thread.
Close #3882.

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.

This assert helps to detect an invalid reference counting in RTEMS_DEBUG
configurations.

Replace rtems_libio_check_fd(), rtems_libio_iop(),
rtems_libio_check_open() and rtems_libio_check_permissions()
combinations with new LIBIO_GET_IOP() and LIBIO_GET_IOP_WITH_ACCESS()
macros.

Remove rtems_libio_check_permissions() and convert single user to
rtems_libio_check_permissions_with_error().

This simplifies error handling later.

Remove the file descriptor validation. This is the job of
rtems_libio_check_fd(). Use an inline function instread of a macro.

Perform a context-dependent deferred location release to avoid a
deadlock on the file system instance locks, for example during a
chdir().
Update #2936.

Add path length parameter to
rtems_filesystem_eval_path_start_with_root_and_current() so that users
may pass paths without a '\0' termination.

Drop parameter check from previously unused

Add a local context structure to the SMP lock API for acquire and
release pairs. This context can be used to store the ISR level and
profiling information. It may be later used to enable more
sophisticated lock algorithms, e.g. MCS locks.
There is only one lock that cannot be used with a local context. This
is the per-CPU lock since here we would have to transfer the local
context through a context switch which is very complicated.

Split the dub call into dup and dup2 in fcntl.c. This requires
a private command which is placed in the internal libio header.

common implementation for all change owner variants.

This is the result of a sed script which converts all uses
of @{ into a consistent form.
