-configure: Fix configuration to match OE-Core requirements
-
-In OE-Core we need to be able to configure for both 32-bit and 64-bit libpseudo
-libraries. In order to avoid some complex manipulations, we adjust the configure
-and Makefile to facilitate this.

- Make opendir/closedir stash and forget directory names.
-
- The dirfd(DIR *) interface allows you to get the fd for a DIR *,
- meaning you can use it with openat(), meaning you can need its
- path. This causes a segfault. Also gonna fix the base_path
- code not to segfault in that case, but first fix the underlying
- problem.

- Implement renameat()
-
- After three long years, someone tried to use this. This was impossibly
- hard back when pseudo was written, because there was only one dirfd
- provided for. Thing is, now, the canonicalization happens in wrapfuncs,
- so a small tweak to makewrappers to recognize that oldpath should use
- olddirfd if it exists is enough to get us fully canonicalized paths
- when needed.
-
- Also fix the crash if base_path gets called with an fd for which we have
- no path.
