Touching all the candy again: [Alex Jackson]
Fixed an annoying inconsistency between memory_share and memory_region: the width() method of the former returned the width in bits (8, 16, 32 or 64) while the width() method of the latter returned the width in bytes (1, 2, 4 or 8). Now both classes have a bitwidth() method and a bytewidth() method. Updated all callers to use whichever one was more appropriate. Removed the implicit-cast-to-any-integer-pointer ability of memory_regions, which was rather unsafe (if you weren't careful with your * operators and casts it was easy to accidentally get a pointer to the memory_region object itself instead of to the data, with no warning from the compiler... or at least I kept doing it) Updated all devices and drivers that were accessing regions that way to use a region_ptr_finder when possible, and otherwise to call base() explicitly.
