[oe] [PATCH] base.bbclass: introduce OE source mirror network as last resort for do_fetch

[Rolf Leggewie]

Updating recipes and checksums.ini for vanishing upstream hosts or simple 
restructuring can quickly become a chore for OE devs if taken seriously. 
The OE user experience suffers severely when at any given point in time 4 
to 5 recipes on average fail do_fetch for a simple image.

The solution is for OE to provide its own caching of upstream sources. 
mirrors.openembedded.org is a swarm of possibly incomplete source mirrors 
provided by the community and load-balanced via DNS round robin.  They 
act as a first line of defense and lower bandwidth load on melo which 
hosts sources.openembedded.org.  The melo mirror aims to have a complete 
copy of free-to-publish sources used by the current org.oe.dev branch.

Some distributions have provided source mirrors in the past for their 
users. I think it's time for a general and all-encompassing solution.

The infrastructure is being currently put in place.  This patch will
turn on the OE sources mirror network by default.
