This introduces a special callback which allows to run code from some MMIO
devices.
SysBusDevice with a MemoryRegion which implements the request_ptr callback will
be notified when the guest try to execute code from their offset. Then it will
be able to eg: pre-load some code from an SPI device or ask a pointer from an
external simulator, etc..
When the pointer or the data in it are no longer valid the device has to
invalidate it.

get_page_addr_code(..) does a cpu_ldub_code to fill the tlb:
This can lead to some side effects if a device is mapped at this address.
So this patch replaces the cpu_memory_ld by a tlb_fill.

This just moves the code before VICTIM_TLB_HIT macro definition
so we can use it.

This replaces env1 and page_index variables by env and index
so we can use VICTIM_TLB_HIT macro later.

there are some types of accelerators in qemu, and all accelerators
have their own file except tcg. tcg accelerator is also defined in
accel.c file. tcg accelerator file will be splited from accel.c and
re-name to tcg-all.c. accel/ directory will be created to include
kvm and tcg related files.
