The ae2810c4bb patch introduced
optimization for ram_list.dirty_memory update. However it can only
work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits
per system page size (may vary, 4K or 64K on PPC64) and
ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE
(which is hardcoded to 4K).
This fixes hpratio!=1 case to fall back to the slow path.

cpu_physical_memory_set_dirty_lebitmap calls getpageaddr and ffsl which are
unavailable for MinGW. As the function is unused for MinGW, it can simply
be excluded from compilation.

If bitmaps are aligned properly, use bitmap operations. If they are
not, just use old bit at a time code.

We want to have all the functions that handle directly the dirty
bitmap near. We will change it later.

All the functions that use ram_addr_t should be here.
