Commit ef96e3ae96 in January 2019 removed the last user of the
VMSTATE_FLOAT64* macros. These were used by targets which defined
their floating point register file as an array of 'float64'.
We used to try to maintain a stricter distinction between
'float64' (a type for holding an integer representing an IEEE float)
and 'uint64_t', including having a debug option for 'float64' being
a struct and supposedly mandatory macros for converting between
float64 and uint64_t. We no longer think that's a usefully
strong distinction to draw and we allow ourselves to freely
assume that float64 really is just a 64-bit integer type, so
for new targets we would simply recommend use of the uint64_t type
for a floating point register file. The float64 type remains
as a useful way of documenting in the type signature of helper
functions and the like that they expect to receive an IEEE float
from the TCG generated code rather than an arbitrary integer.
Since the VMSTATE_FLOAT64* macros have no remaining users and
we don't recommend new code uses them, delete them.

Non-empty record/replay queue prevents saving and loading the VM state,
because it includes pending bottom halves and block coroutines.
But when the new VM state is loaded, we don't have to preserve the consistency
of the current state anymore. Therefore this patch just flushes the queue
allowing the coroutines to finish and removes checking for empty rr queue
for load_snapshot function.

Saving icount as a parameters of the snapshot allows navigation between
them in the execution replay scenario.
This information can be used for finding a specific snapshot for proceeding
the recorded execution to the specific moment of the time.
E.g., 'reverse step' action (introduced in one of the following patches)
needs to load the nearest snapshot which is prior to the current moment
of time.
This patch also updates snapshot test which verifies qemu monitor output.

duplicating the logic. Also, when we have the rb pointer, it's also easier to

ramblock when needed, or the page size) can be fetched from the ramblock

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:
$ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \
sort -u >/tmp/changed_identifiers
$ for identifier in $(</tmp/changed_identifiers); do
sed -i "s%\<$identifier\>%q$identifier%g" \
$(git grep -I -l "\<$identifier\>")
done

Some trace points are attributed to the wrong source file. Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.
Clean up with help of scripts/cleanup-trace-events.pl. Funnies
requiring manual post-processing:
* accel/tcg/cputlb.c trace points are in trace-events.
* block.c and blockdev.c trace points are in block/trace-events.
* hw/block/nvme.c uses the preprocessor to hide its trace point use
from cleanup-trace-events.pl.
* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
guard debug code.
* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.
* linux-user/trace-events abbreviates a tedious list of filenames to
*/signal.c.
* net/colo-compare and net/filter-rewriter.c use pseudo trace points
colo_compare_miscompare and colo_filter_rewriter_debug to guard
debug code.
