containerfs: rewrite it to use *at functions
do not use absolute paths when accessing files.  Use relative paths to
the layers root.  As part of the refactoring, also drop any cache of
the lower layers, working more similarly as overlay in the kernel.

containerfs
===========
An implementation of overlay+shiftfs in FUSE for rootless containers.
Known issues:
=======================================================
Hard links in some cases show different inode values.
Read-only mode is not supported, so it is always required to specify
an upperdir and a workingdir.
Usage:
=======================================================
```
$ containerfs -o lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
```
Specify a different UID/GID mapping:
```
$ containerfs -o uid=0:10:100:100:10000:2000,gid=0:10:100:100:10000:2000,lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
```
