qemu_log_lock/unlock now preserves the qemu_logfile handle.

Browse source 
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a
handle to unlock.  This allows for changing the handle during logging
and ensures the lock() and unlock() are for the same file.

Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock()
calls (and the log("\n")), since the translator can longjmp out of the
loop if it attempts to translate an instruction in an inaccessible page.
