Sebastian Huber 483e696049 RTEMS: Increase SEM_VALUE_MAX
RTEMS defined SEM_VALUE_MAX to 32767 unlike other systems like FreeBSD
and glibc.  A common value is INT_MAX.

Sebastian Huber 724e21493a Self-contained pthread_spinlock_t for RTEMS
Turn pthread_spinlock_t into a self-contained object.  On uni-processor
configurations, interrupts are disabled in the lock/trylock operations
and the previous interrupt status is restored in the corresponding
unlock operations.  On SMP configurations, a ticket lock is a acquired
and released in addition.

This implementation is simple and efficient.  However, this test case of
the Linux Test Project would fail due to call of printf() and sleep()
during spin lock ownership:

Sebastian Huber e655d3d34b Move pthread types to <sys/_pthreadtypes.h>
This makes it possible provide operating system specific types for
<pthread.h>.  It is in line with the FreeBSD header file structure and
allows a future cleanup of <pthread.h> to not expose unrelated things
via <sys/types.h> and <unistd.h>.  Glibc uses the similar
<bits/pthreadtypes.h> for this purpose.

Sebastian Huber 8a5af1a184 Use __machine_*_t_defined for internal types
Newlib defines defaults for internal types via <sys/_types.h> and uses
<machine/_types.h> to let targets define their own type if necessary.

Previously for example

	#ifndef __dev_t_defined
	typedef short __dev_t;
	#endif

However, the __*_t_defined pattern conflicts with the glibc type guard
pattern for user types, e.g. dev_t in this example.  Introduce a
__machine_*_t_defined pattern for internal types (defined by
<machine/_types.h>, used by <sys/_types.h>).  For example

	#ifndef __machine_dev_t_defined
	typedef short __dev_t;
	#endif

Sebastian Huber 477463a201 Eliminate use of Newlib-specific <machine/types.h>
This change solves a glibc/BSD compatibility problem.

glibc and BSD use double underscore types for internal types.  The Linux
port of Newlib uses some glibc provided internal type definitions which
are not protected by guard defines, e.g. __off_t.  To avoid a conflict
Newlib uses single underscore types for some internal types, e.g.
_off_t.  However, for BSD compatibility we have to define the internal
types with double underscore names in <sys/_types.h>.

The header file <machine/types.h> is Newlib-specific.  It was used
instead of <sys/_types.h> to provide the internal type definitions
_CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t.  Move
these definitions to <sys/_types.h> (there exist two instances of this
file, one for Linux and one for all other targets).  This makes the
_HAVE_SYSTYPES configuration define obsolete (could possibly break the
__RDOS__ target).  Use the standard <sys/_types.h> include throughout.

Move __loff_t defintion to default (non-Linux) <sys/_types.h>.  Define
it via _off64_t to avoid a dependency on the compiler.

Provide the __off_t definition via default (non-Linux) <sys/_types.h>
based on _off_t for all systems except Cygwin.  For Cygwin use _off64_t.
Define off_t via __off_t.

Provide the __pid_t definition via default (non-Linux) <sys/_types.h>.
This prevents a potential __pid_t and pid_t incompatibility.  Add BSD
guard defines for pid_t.

Sebastian Huber f74cf1350e Add arc4random() etc. from OpenBSD 5.8
According to the OpenBSD man page, "A Replacement Call for Random".  It
offers high quality random numbers derived from input data obtained by
the OpenBSD specific getentropy() system call which is declared in
<unistd.h> and must be implemented for each Newlib port externally.  The
arc4random() functions are used for example in LibreSSL and OpenSSH.

Cygwin provides currently its own implementation of the arc4random
family.  Maybe it makes sense to use this getentropy() implementation:
