radeon.man.patch

1) radeon.man.patch
- clarify supported features (hoping that users stop asking things like "why I can't use Xv on my RV670?" in irc/forum/ml);
- improve readability avoiding adding an empty line between every card in the SUPPORTED HARDWARE;

2) ati_pciids.csv.patch
- remove some duplicated "ATI ATI " in cards name

Also some things to ask:

a) ati_pciids.csv says that the "ATI Radeon HD 4870 x2" is a RV770. Shouldn't says R700?

b) MergedFB support was removed some time ago. However a grep -ri mergedfb revealed there are some traces of it (mostly in comments), e.g.:

src/radeon_driver.c:

   if (xf86IsEntityShared(info->pEnt->index)) {
        xf86DrvMsg(pScrn->scrnIndex, X_WARNING,
                   "Direct Rendering Disabled -- "
                   "Dual-head configuration is not working with "
                   "DRI at present.\n"
                   "Please use the radeon MergedFB option if you "
                   "want Dual-head with DRI.\n");
        return FALSE;
    }

src/legacy_crtc.c:

/* note cannot use pScrn->pScreen since this is unitialized when called from
RADEONScreenInit, and we need to call from there to get mergedfb + pageflip working */
