Right now, the stub BQL in stubs/iothread-lock.c always reports itself as unlocked. However, Rust would like to run its tests in an environment where the BQL *is* locked. Provide an extremely dirty function that flips the return value of bql_is_locked() to true. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
