bsd-user: Next round of syscalls

Implement the next round of system calls. These are open, openat, close,
fdatasync, fsync, close_from, revoke, access, eacccess, facccessat, chdir,
fchdir, rename, renameat, mkdir, mkdirat, rmdir, _getcwd, dup, dup2, truncate,
ftruncate, acct and sync. In addition, the helper functions needed for these to
work are included. With the helper functions, all of these system calls are the
'obvious' wrapper...
