I have one of these too that reinvents the wheel.  The main reason was 
to enable bdrv_aio_* implementations.

I'm happy to merge a version that uses libcurl but I don't want to merge 
it unless it's implementing bdrv_aio_.  As far as I'm concerned, 
backends implementing bdrv_read/bdrv_write is deprecated.
