67b3f58c83 ulimit: remove buggy bsd implementation
The bsd implementation of ulimit produces wrong return values, so remove it
in favour of the posix implementation.

The only regression for non-Linux implementations using bsd sysdeps and not
providing an own ulimit is that the __UL_GETMAXBRK case (which is non-standard)
is left unimplemented (giving EINVAL).

9cbbc4aebe ulimit: move linux implementation as posix
The linux implementation of ulimit works correctly and has nothing specific
to Linux, so move it as general posix implementation.

Anton Blanchard
471a1672d4 PowerPC: Rename __kernel_vdso_get_tbfreq to __kernel_get_tbfreq.
In order for the __kernel_get_tbfreq vDSO call to work the
INTERNAL_VSYSCALL_NCS macro needed to be updated to prevent it from
assuming an integer return type (since the timebase frequency is a 64-bit
value) by specifying the type of the return type as a macro parameter.  The
macro then specifically declares the return value as a 'register' (or
implied pair) of the denoted type.  The compiler is then informed that this
register (or implied pair) is to be used for the return value.

2a26ef3a01 Add HAVE_MREMAP for mremap usage
Introduce (only on Linux) and use a HAVE_MREMAP symbol to advertize mremap
availability.

Move the malloc-sysdep.h include from arena.c to malloc.c, since what is
provided by malloc-sysdep.h is needed earlier in malloc.c, before the inclusion
of arena.c.

357679d2fc scsi/sg.h: include stddef.h for size_t
This header uses size_t but doesn't include stddef.h for it.  So when
packages happen to include this before any header that defines size_t,
they get a build failure.
