Fix this by introducing a new header file <asm/syscalls.h> for holding
the prototypes for m68k-specific syscalls, and including the generic
ones.

The arch/m68k/lib versions of the libgcc functions: ashldi3, ashrdi3
and lshrdi3 were taken directly from an older version of gcc.
We can use the kernel's own generic lib versions of these - they are
virtually identical. Switch to those and remove the m68k local ones.

strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
Direct replacement is safe here since return value of -errno
is used to check for truncation instead of sizeof(dest).

Replace the (incorrect) external declarations by an inclusion of the
appropriate header file.
Semantically, the "src" parameters of the various fp_*() functions are
constant. However, they cannot actually be const as most of these
functions perform a normalization step first. As the fp_one constant
passed to fp_add() is already normalized, it is safe to cast away its
constness when making the function call.

commit 'be65de6b03aa ("fs: Remove dcookies support")' removed the
syscall definition for lookup_dcookie. However, syscall tables still
point to the old sys_lookup_dcookie() definition. Update syscall tables
of all architectures to directly point to sys_ni_syscall() instead.

Finish off the 'simple' futex2 syscall group by adding
sys_futex_requeue(). Unlike sys_futex_{wait,wake}() its arguments are
too numerous to fit into a regular syscall. As such, use struct
futex_waitv to pass the 'source' and 'destination' futexes to the
syscall.
This syscall implements what was previously known as FUTEX_CMP_REQUEUE
and uses {val, uaddr, flags} for source and {uaddr, flags} for
destination.
This design explicitly allows requeueing between different types of
futex by having a different flags word per uaddr.

To complement sys_futex_waitv()/wake(), add sys_futex_wait(). This
syscall implements what was previously known as FUTEX_WAIT_BITSET
except it uses 'unsigned long' for the value and bitmask arguments,
takes timespec and clockid_t arguments for the absolute timeout and
uses FUTEX2 flags.
The 'unsigned long' allows FUTEX2_SIZE_U64 on 64bit platforms.
