Avi Kivity 99a15de9e5 logger: de-thread_local-ize logger ...

The logger class constructor registers itself with the logger registry,
in order to enable dynamically setting log levels.  However, since
thread_local variables may be (and are) initialized at the time of first
use, when the program starts up no loggers are registered.

Fix by making loggers global, not thread_local.  This requires that the
registry use locking to prevent registration happening on different threads
from corrupting the registry.

Note that technically global variables can also be initialized at the
point of first use, and there is no portable way for classes to self-register.
However this is the best we can do.
