clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:
$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)
Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.
This patch was generated using:

This change switches linux-user strace logging to use the newer `qemu_log`
logging subsystem rather than the older `gemu_log` (notice the "g")
logger. `qemu_log` has several advantages, namely that it allows logging
to a file, and provides a more unified interface for configuration
of logging (via the QEMU_LOG environment variable or options).
This change introduces a new log mask: `LOG_STRACE` which is used for
logging of user-mode strace messages.

This now allows changing the logfile while logging is active,
and also solves the issue of a seg fault while changing the logfile.
Any read access to the qemu_logfile handle will use
the rcu_read_lock()/unlock() around the use of the handle.
To fetch the handle we will use atomic_rcu_read().
We also in many cases do a check for validity of the
logfile handle before using it to deal with the case where the
file is closed and set to NULL.
The cases where we write to the qemu_logfile will use atomic_rcu_set().
Writers will also use call_rcu() with a newly added qemu_logfile_free
function for freeing/closing when readers have finished.

If giving QEMU a log arg which asks to enable multiple
different trace event patterns such as
$QEMU -d trace:qio*,trace:qcrypto*
the parser will then invoke
trace_enable_events("qio*,trace:qcrypto*")
trace_enable_events("qcrypto*")
as when finding a 'trace:' prefix, it is not clever
enough to strip anything after the next comma. As
a result only the last 'trace:' match ever works.
Rather than trying to be more clever with parsing the
command line arg in place, simplify the code by
using g_strsplit to break it into individual strings
on ','. These resulting pieces can be directly used
without worrying about trailing data from the next

Rather than rely on recursion during the middle of register allocation,
lower indirect registers to loads and stores off the indirect base into
plain temps.
For an x86_64 host, with sufficient registers, this results in identical
code, modulo the actual register assignments.
For an i686 host, with insufficient registers, this means that temps can
be (temporarily) spilled to the stack in order to satisfy an allocation.
This as opposed to the possibility of not being able to spill, to allocate
a register for the indirect base, in order to perform a spill.

Range encodes an integer interval [a,b] as { begin = a, end = b + 1 },
where a \in [0,2^64-1] and b \in [1,2^64]. Thus, zero end is to be
interpreted as 2^64.
The implementation of -dfilter (commit 3514552) uses Range
differently: it encodes [a,b] as { begin = a, end = b }. The code
works, but it contradicts the specification of Range in range.h.
Switch to the specified representation. Since it can't represent
[0,UINT64_MAX], we have to reject that now. Add a test for it.
While we're rejecting anyway: observe that we reject -dfilter LOB..UPB
where LOB > UPB when UPB is zero, but happily create an empty Range
when it isn't. Reject it then, too, and add a test for it.
While there, add a positive test for the problematic upper bound

Commit 96c33a4 ("log: Redirect stderr to logfile if deamonized",
2016-02-22) wanted to move stderr of a daemonized QEMU to the file
specified with -D.
However, if -D was not passed, the patch had the side effect of not
redirecting stderr to /dev/null. This happened because qemu_logfile
was set to stderr rather than the expected value of NULL. The fix
is simply in the "if" condition of do_qemu_set_log; the "if" for
closing the file is also changed to match.
