bluecherrydvr/solo6x10 — Issue #19: OSD writes are much larger than necessary

In solo_osd_print, the entire OSD area (65kb or 130kb) for that channel is overwritten, but there is currently no API that allows changing any more than the first ~750 bytes. It would be much more efficient to initialize the area to 0 and only overwrite the first 4096 bytes (due to the quirky DMA alignment requirements) in solo_osd_print.
