Iteratively parse filelists.xml and other.xml, to avoid over-use of memory.
createrepo_c parses everything in bulk, into memory. For large repositories such as
RHEL 7 or OL 7, this can require more than 5gb of memory. That isn't acceptable, especially
when many repositories are being synced at once. The main offenders are other.xml (changelogs)
and filelists.xml (list of owned files). These also happen to be relatively easy to parse.
This function, ported from Pulp 2, takes a path to filelists.xml and other.xml, creates
a streaming parser for each, and then yields one package worth of data from each file.
