Support /etc/portage/binrepos.conf as a replacement for the
PORTAGE_BINHOST variable. Behavior is similar to repos.conf,
initially supporting just the sync-uri attribute. Both binrepos.conf
and PORTAGE_BINHOST can be used simultaneously, in the same way that
repos.conf and PORTDIR_OVERLAY can be used simultaneously.
The emerge --info output for binrepos.conf looks like this:
Binary Repositories:
