Store tcg loop exit request on a global variable, and transfer it to
per-CPUState exit_request after assignment of cpu_single_env.
This makes exit request signal from robust. Drop the timedlock hack.

The bug is that env->stopped is not really as comprehensive as it seems to
be (and cpu_has_work thinks); it is only valid with iothread basically,
and even then it is cleared by reset and it is not set when starting
qemu with -S.

Arrange various declarations so that also non-CPU code can access
them, adjust users.
Move CPU specific code to cpus.c.
