Better inplace scan3

If you try to call __str__ before compiling the function the destroy_map
attribute might not exist.

The optimization before was all or nothing, which is a bad compromise for
scan. This new optimization tries to work in place on each outputs, and
keeps only those for which it can. This way you do not get your entire op to
be non-inplace because of a single output that can not be computed inplace.

Fixes to CentOS instructions, etc.

fix clear_unversioned. When there is no key file, we should use the compiled module to check the time.

As we check access time, we won't delete them as we update the access time of the directory when we list it.
It was working fine when we used the modification time.
