fbdev: copyarea function taught to fully support swapped pixel order in byte
This correct case, when source and destination X coordinates difference is n
multiple of pixels in byte. This is probably rare case, but this case should
supported for completeness.
Reorganization of FB_READL and FB_WRITEL calls results in code size decrease
for normal build without swapping support and size with support enabled is
reasonable too.
[adaplas]
Add missing fb_rev_pixels_in_long() prototype.
