pseudo: Enhancements
Enable changing the data directory on the fly from the environment and then use this feature within poky to confine pseudo usage to each WORKDIR. This fixes issues that could be seen under heavy inode reusage e.g. with rm_work. Work based mainly off a patch from Joshua Lock but finished by Richard Purdie.

1We observed the pseudo database becoming large and corrupted when undergoing
2significant use (generating multiple output package types).

4This patch checks for the existence of an PSEUDO_DATADIR environment variable
5and, when it exists, uses the directory specified there to store the pseudo
6database. This should enable us to use a different database for each run of
7pseudo.
