Stefan Hajnoczi ac90871cf8 lockable: add QemuRecMutex support
The polymorphic locking macros don't support QemuRecMutex yet.  Add it
so that lock guards can be used with QemuRecMutex.

Convert TCG plugins functions that benefit from these macros.  Manual
qemu_rec_mutex_lock/unlock() callers are left unmodified in cases where
clarity would not improve by switching to the macros.

Alex Bennée 3fb356cc86 tcg plugins: expose an API version concept
This is a very simple versioning API which allows the plugin
infrastructure to check the API a plugin was built against. We also
expose a min/cur API version to the plugin via the info block in case
it wants to avoid using old deprecated APIs in the future.

This provides a limited amount of info to plugins about the guest
system that will allow them to make some additional decisions on
setup.
