__clone stub for i386

b25c2304f3
I have no idea why this syscall wrapper does some very un-unix-like
...
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.
*
* However, I do know that it should use jb and not jl.

A better fix for the stub-in-other-module problem:

Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d
...
in their respective header files). Add PSEUDO stubs for the old versions
of these system calls.
Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

Warn about references to the compatibility vfork() (i.e. the vfork() with

Add syscall stubs for __vfork14(). These are basically copies of Ovfork.S
...
with the syscall numbers changed.
Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers). __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns. (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)
