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...

I've tried to lump these together with related functions in the same change, all
less than 100 lines per change (most less than 40). This represents a little
over 1/3 of the remaining system calls related to files (we have quite a few
more cagegories to go through). I think the lumping represents a good trade-off
between 'small enough to review' and 'few enough parts to not add too much
overhead' vs 'one commit per system call' which would have bloated this series
to 35 pieces. I hope to do the remaining system calls at this chunk granularity
and maybe twice as many parts to get through the ~15k backlog I still have to go
through.
