Abstract mapping/unmapping of flash regions
Flash mapping/unmapping was performed without an abstraction layer, so even the dummy flasher caused memory mappings to be set up. Add map/unmap functions to the external flasher abstraction. Fix a possible scribble-over-low-memory corner case which fortunately never triggered so far. With this patch, --programmer dummy works fine as non-root. Corresponding to flashrom svn r493.
