Marco Casaroli 9b787d42b2 sched/arch/libc: make task_fork() optional

task_fork() is a NuttX extension, not POSIX, and a configuration that does
not call it has no reason to carry it.  Add CONFIG_TASK_FORK to leave it out.

It depends on ARCH_HAVE_TASK_FORK and defaults to y, so it is enabled exactly
where fork() existed before the split and no configuration loses the primitive
by upgrading.  ARCH_HAVE_TASK_FORK keeps its meaning -- the architecture *can*
clone the calling task -- and the new symbol says whether this build wants it.
Everything that provides task_fork() moves to the new symbol:  the declaration
in sched.h, up_task_fork() in arch.h, the two .csv entries that generate the
system call stub and proxy, the syscall_lookup.h table entry, the architecture
entry points, and the build rules for the files that hold them.

FORK_IS_TASK_FORK now depends on TASK_FORK rather than ARCH_HAVE_TASK_FORK.
Aliasing fork() to a task_fork() that was not built would not link.

vfork() and fork() are untouched; each is still selected on its own, and
task_fork.c, lib_fork.c and the architecture's fork file are still built when
any one of the three is present.
