x86 was using additional CPU_DUMP_* flags, so make that configurable in
CPUClass::reset_dump_flags.

This adds reset logging for alpha, unicore32 and xtensa.

Since commit 878096ee (cpu: Turn
cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no
longer needed.

Add documentation and make the functions available through qemu/log.h
outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h
was not yet possible due to convoluted include paths, so that some
devices grow an implicit and unneeded dependency on qom/cpu.h for now.

Use it for all targets, but be careful not to pass invalid CPUState.
cpu_single_env can be NULL, e.g. on Xen.

This allows to move the call into CPUState's realizefn.
Therefore move the stub into libqemustub.a.

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions.

The field may not be called "env" due to it being poisoned.

Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.
