    Flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.
    
    As discussed in
    <https://sourceware.org/ml/libc-alpha/2012-04/msg00840.html> and
    <https://sourceware.org/ml/libc-alpha/2012-04/msg00989.html>, it seems
    appropriate to flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.
    
    The bulk of the patch is just moving files.  The only other changes
    are: update paths in sysdeps/mach/hurd/Implies and
    sysdeps/unix/sysv/linux/wait3.c; merge the two syscalls.list files,
    with the removal of syscalls that were in
    sysdeps/unix/bsd/syscalls.list but overridden in the bsd4.4 directory
    by .c files there.
    
    Tested x86_64.  The installed shared libraries are identical before
    and after the patch except for libc.so where the move of wait3.c
    (included by sysdeps/unix/sysv/linux/wait3.c) affects debug info, but
    the disassembly is unchanged.
    
            * sysdeps/mach/hurd/Implies: Change unix/bsd/bsd4.4 to unix/bsd.
            * sysdeps/unix/bsd/syscalls.list (chflags): Add entry from
            sysdeps/unix/bsd/bsd4.4/syscalls.list.
