Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be
linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY)
to make it fail on old kernels.
Copying definitions from glibc for O_TMPFILE is not enough to support
O_TMPFILE; The open() wrapper also need to pass the mode when the flag
contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed
but yield unexpected results.
openat() is curiously not affected since it passes the mode
unconditionally..

Rename various spare fields in structs to include a namespace
This should avoid accidental clashes with uses of the __unused symbol
in upstream projects. eg currently it causes a compile error in dhcpcd 8.x
due to their re-use of the __unused symbol as a macro
This follows the style of glibc which does something equivalent

we need to handle Linux kernel change, which removed stat64 family from default syscall set.

License notices in most of the source files refer to an outdated
FSF address. Replace it with URL, like in the rest of the source

Only alpha, hppa and sparc need non-default value.

.globl can be used for every architecture so remove the define.
Sync with GNU C library.

It's even no longer required for non-ported ppc64
architecture. Sync with GNU C library.
This simplify the macros in include/libc-symbols.h.

Add __kernel_long_t and __kernel_ulong_t types for Meta. The rest of
the architectures have been fixed in:

The reason truncate64 takes 4 args on some arches is that their ABI
requires 64bit values to be aligned on register pair boundaries.
Since this alignment affects more than just truncate64, rename the
define to properly document its purpose. This also allows us to
expand it to the other impacted syscalls (which will be done in a
follow up commit).

Meta cores are 32-bit, hardware multithreaded, general purpose, embedded
processors which also feature a DSP instruction set, and can be found in
many digital radios. They are capable of running different operating
systems on different hardware threads, for example a digital radio might
run RTOSes for DAB decoding and audio decoding on 3 hardware threads,
and run Linux on the 4th hardware thread to manage the user interface,
networking etc. HTPs are also capable of running SMP Linux on multiple
hardware threads.
