This field was used for telling cpu_interrupt() to unlink a chain of TBs
being executed when it worked that way. Now, cpu_interrupt() don't do
this anymore. So we don't need this field anymore.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes.

Gather up all the fields currently in CPUState which deal with the CPU's
AddressSpace into a separate CPUAddressSpace struct. This paves the way
for allowing the CPU to know about more than one AddressSpace.
The rearrangement also allows us to make the MemoryListener a directly
embedded object in the CPUAddressSpace (it could not be embedded in
CPUState because 'struct MemoryListener' isn't defined for the user-only
builds). This allows us to resolve the FIXME in tcg_commit() by going
directly from the MemoryListener to the CPUAddressSpace.
This patch extracts the actual update of the cached dispatch pointer
from cpu_reload_memory_map() (which is renamed accordingly to
cpu_reloading_memory_map() as it is only responsible for breaking
cpu-exec.c's RCU critical section now). This lets us keep the definition
of the CPUAddressSpace struct private to exec.c.

operations
The reason for cpu_reload_memory_map()'s RCU operations is not
so much because the guest could make the critical section very
long, but that it could have a critical section within which
it made an arbitrary number of changes to the memory map and
thus accumulate an unbounded amount of memory data structures
awaiting reclamation. Clarify the comment to make this clearer.

The goal is to split the functions such that cpu-exec is CPU specific
content, while cpus-exec-common.c is generic code only. The function
interface to cpu-exec needs to be virtualised to prepare support for
multi-arch and moving these definitions out saves bloating the QOM
interface. So move these definitions out of cpu-exec to a new module,
cpu-exec-common.
