[rrd-developers] [PATCH] add 'flush' to language bindings

[kevin brintnall]

Tobi,

This 2-patch series exposes 'flush' methods to the various language
bindings.

I noticed that most of the other API-visible functions are "rrd_X", but
flush is "rrd_cmd_flush".  Should we rename to "rrd_flush" to match the
others? The only problem I can see is potential confusion with
"rrdc_flush".  Maybe we should rename both?

Patches to follow...
