vfs: add a 'reljoin' function for joining relative paths
The vfs.join method only works for absolute paths. We need something
that works for relative paths too when transforming filenames. Since
os.path.join may misbehave in tricky encoding situations, encapsulate
the new join method in our vfs abstraction. The default implementation
remains os.path.join, but this opens the door to other VFSes doing
something more intelligent based on their needs.
In the same go, we replace the usage of 'os.path.join' in transaction code.
