Compressing .meta file also?

[Nathan Scott <nathans@xxxxxxxxxx>]

Hi Ken,

I've seen two cases this week of people starting to get sufficiently
large archive .meta files that compression has been requested, or at
least considered (both times from the well known proc-indom issue).

As a stop-gap, is there any reason we'd not be able to auto-compress/
auto-expand the .meta files as well?  Not a long-term fix but has the
nice quality of being relatively backward-compatible ("just" a libpcp
change to add support, and some pmlogger_daily shell code I guess).

thanks.
