Plugin Register Accesses

[Aaron Lindsay]

I'm trying to migrate to using the new plugin interface. I see the
following in include/qemu/qemu-plugin.h:

> enum qemu_plugin_cb_flags {
>     QEMU_PLUGIN_CB_NO_REGS, /* callback does not access the CPU's regs */
>     QEMU_PLUGIN_CB_R_REGS,  /* callback reads the CPU's regs */
>     QEMU_PLUGIN_CB_RW_REGS, /* callback reads and writes the CPU's regs */
> };

But I don't see a way to access registers in callbacks. Am I missing
something?
