memory: split dirty bitmap into three

After all the previous patches, spliting the bitmap gets direct.

Note: For some reason, I have to move DIRTY_MEMORY_* definitions to
the beginning of memory.h to make compilation work.

exec: Reduce ifdeffery around -mem-path

Instead of spreading its ifdeffery everywhere, confine it to
qemu_ram_alloc_from_ptr(). Everywhere else, simply test block->fd,
which is non-negative exactly when block uses -mem-path.

linux-user: fix segmentation fault passing with h2g(x) != x

When forwarding a segmentation fault into the guest process, we were passing
the host's address directly into the guest process's signal descriptor.

That obviously confused the guest process, since it didn't know what to make...

cpu: Make first_cpu and next_cpu CPUState

Move next_cpu from CPU_COMMON to CPUState.
Move first_cpu variable to qom/cpu.h.

gdbstub needs to use CPUState::env_ptr for now.
cpu_copy() no longer needs to save and restore cpu_next.

protect the ramlist with a separate mutex

Add the new mutex that protects shared state between ram_save_live

with the ramlist mutex, the iothread shall always be outside.

exec: change ramlist from MRU order to a 1-item cache

Most of the time, only 2 items will be active (from/to for a string operation,
or code/data). But TCG guests likely won't have gigabytes of memory, so
this actually goes down to 1 item.
