Generate /etc/services from
https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml
and a locally maintained local.xml.
This required creating the initial version of local.xml, which
was also automated. (The code for this can be removed when we are
sure it is no longer needed.) All of our current /etc/services names
still exist, although the official name and comment for a given
number/protocol tuple are determined by the IANA registry, so they
might have changed.
/etc/services grows from 2,367 lines and 2,501 names to 11,538 lines
and 12,005 names. /var/db/services.db grows from 2 MB to 4.2 MB.
