Day 17 so far:
* New syscalls: chdir, fchdir, pipe; getpid/getppid removed, replaced with getcreds (also does uid, gid, euid, sid, etc)
* Mountpoints refactored to live on inodes, all *at (e.g. openat) syscalls finished
* C++ running in userspace (ugh, needed for a future gcc port)
* Bunnix target patched into binutils & gcc cross toolchain, proper sysroot set up
* libc expanded: dirent, getopt, stat, time, plus riggings for the new syscalls (e.g. pipe, getuid)
