548fb0da73 qga: move qga_get_host_name()
The function is specific to qemu-ga, no need to share it in QEMU.

756a98dd70 Move error_printf_unless_qmp() with monitor unit
Since it depends on monitor code, and error_vprintf_unless_qmp() is
already there.

This will help to move error-report in a common subproject.

c213ef9a66 compiler.h: add QEMU_SANITIZE_{ADDRESS,THREAD}
Simplify a bit pre-compiler conditions.

For TSAN, QEMU already has CONFIG_TSAN, but it is only set when the
fiber API is present. (I wonder whether supporting TSAN without the
fiber API is really relevant)

c74824389e tcg: Fix indirect lowering vs TCG_OPF_COND_BRANCH
With TCG_OPF_COND_BRANCH, we extended the lifetimes of
globals across extended basic blocks.  This means that
the liveness computed in pass 1 does not kill globals
in the same way as normal temps.

Introduce TYPE_EBB to match this lifetime, so that we
get correct register allocation for the temps that we
introduce during the indirect lowering pass.

4e51069d67 util/log: Support per-thread log files
Add a new log flag, tid, to turn this feature on.
Require the log filename to be set, and to contain %d.

Do not allow tid to be turned off once it is on, nor let
the filename be change thereafter.  This avoids the need
for signalling each thread to re-open on a name change.

30f5a73ac3 util/log: Limit RCUCloseFILE to file closing
Use FILE* for global_file.  We can perform an rcu_read on that
just as easily as RCUCloseFILE*.  This simplifies a couple of
places, where previously we required taking the rcu_read_lock
simply to avoid racing to dereference RCUCloseFile->fd.

Only allocate the RCUCloseFile prior to call_rcu.

ec0d1849d9 util/log: Remove qemu_log_close
The only real use is in cpu_abort, where we have just
flushed the file via qemu_log_unlock, and are just about
to force-crash the application via abort.  We do not
really need to close the FILE before the abort.

The two uses in test-logging.c can be handled with
qemu_set_log_filename_flags.
