----------------------------------------------------------------
Memory API patches

- Reduce 'qemu/bswap.h' uses
- Introduce ldm_p/stm_p (MemOp) load/store helpers
- Allow restricting the legacy 'native-endian' APIs
- Forbid various targets to use legacy native endianness APIs
- Simplify cpu_address_space_init() API
