exec: return MemoryRegion from address_space_translate

Only address_space_translate_for_iotlb needs to return the section.
Every caller of address_space_translate now uses only section->mr,
return it directly.

memory: add address_space_translate

Using phys_page_find to translate an AddressSpace to a MemoryRegionSection
is unwieldy. It requires to pass the page index rather than the address,
and later memory_region_section_addr has to be called. Replace
memory_region_section_addr with a function that does all of it: call...

PPC: Fix compile with profiling enabled

When using profiling, we rely on profile_getclock() being available
at our disposal. Somehow that function got moved from an indirect
include we used to have in translate-init.c, so that we were now
left not properly compiling anymore....

include: avoid useless includes of exec/ headers

Headers in include/exec/ are for the deepest innards of QEMU,
they should almost never be included directly.

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

translate-all.c: Remove cpu_unlink_tb()

The (unsafe) function cpu_unlink_tb() is now unused, so we can simply
remove it and any code that was only used by it.

TCG: Move translation block variables to new context inside tcg_ctx: tb_ctx

It's worth to clean-up translation blocks variables and move them
into one context as was suggested by Swirl.
Also if we use this context directly inside tcg_ctx, then it
speeds up code generation a bit....

translate-all.c: Use tb1->phys_hash_next directly in tb_remove

QEMU host addresses must use uintptr_t to be portable for hosts with
