354908cee1 riscv: Add helper to make NaN-boxing for FP register
The function that makes NaN-boxing when a 32-bit value is assigned
to a 64-bit FP register is split out to a helper gen_nanbox_fpr().
Then it is applied in translating of the FLW instruction.

ca64b08638 tpm: Move backend code under the 'backends/' directory
TPM subsytem is split into backends (see commit f4ede81eed)
and frontends (see i.e. 3676bc69b3). Keep the emulated
hardware 'frontends' under hw/tpm/, but move the backends
in the backends/tpm/ directory.

0f7d214820 hw/tpm: Make 'tpm_util.h' publicly accessible as "sysemu/tpm_util.h"
We are going to split the TPM backends from the TPM emulated
hardware in the next commit. Make the TPM util helpers accessible
by moving local "tpm_util.h" to global "sysemu/tpm_util.h".

a3500613bd hw/tpm: Move DEFINE_PROP_TPMBE() macro to 'tmp_prop.h' local header
We are going to make "tpm_util.h" publicly accessible by
moving it to the include/ directory in the next commit.
The DEFINE_PROP_TPMBE() macro is only meaningful for the
TPM hardware files (in hw/tpm/), so keep this macro in a
local header.

f670a562af hw/tpm: Make TRACE_TPM_UTIL_SHOW_BUFFER check local to tpm_util.c
The trace_event_get_state_backends() call is useful to avoid
making extensive calls (usually preparing arguments passed to
the tracing framework. In this case, the extensive work is
done in tpm_util_show_buffer(), and the arguments used to
call it don't involve extra processing. Simplify by moving
the TRACE_TPM_UTIL_SHOW_BUFFER check to tpm_util_show_buffer.

71830d8430 net: Drop the NetLegacy structure, always use Netdev instead
Now that the "name" parameter is gone, there is hardly any difference
between NetLegacy and Netdev anymore, so we can drop NetLegacy and always
use Netdev to simplify the code quite a bit.

The only two differences that were really left between Netdev and NetLegacy:

1) NetLegacy does not allow a "hubport" type. We can continue to block
   this with a simple check in net_client_init1() for this type.

2) The "id" parameter was optional in NetLegacy (and an internal id
   was chosen via assign_name() during initialization), but it is mandatory
   for Netdev. To avoid that the visitor code bails out here, we have to
   add an internal id to the QemuOpts already earlier now.

45942b79b9 net/colo-compare.c: Check that colo-compare is active
If the colo-compare object is removed before failover and a
checkpoint happens, qemu crashes because it tries to lock
the destroyed event_mtx in colo_notify_compares_event.

Fix this by checking if everything is initialized by
introducing a new variable colo_compare_active which
is protected by a new mutex colo_compare_mutex. The new mutex
also protects against concurrent access of the net_compares
list and makes sure that colo_notify_compares_event isn't
active while we destroy event_mtx and event_complete_cond.

With this it also is again possible to use colo without
colo-compare (periodic mode) and to use multiple colo-compare
for multiple network interfaces.

9c55fe9408 net/colo-compare.c: Fix deadlock in compare_chr_send
The chr_out chardev is connected to a filter-redirector
running in the main loop. qemu_chr_fe_write_all might block
here in compare_chr_send if the (socket-)buffer is full.
If another filter-redirector in the main loop want's to
send data to chr_pri_in it might also block if the buffer
is full. This leads to a deadlock because both event loops
get blocked.

Fix this by converting compare_chr_send to a coroutine and
putting the packets in a send queue.

d9b6964039 Fix tulip breakage
The tulip network driver in a qemu-system-hppa emulation is broken in
the sense that bigger network packages aren't received any longer and
thus even running e.g. "apt update" inside the VM fails.

The breakage was introduced by commit 8ffb7265af ("check frame size and
r/w data length") which added checks to prevent accesses outside of the
rx/tx buffers.

But the new checks were implemented wrong. The variable rx_frame_len
counts backwards, from rx_frame_size down to zero, and the variable len
is never bigger than rx_frame_len, so accesses just can't happen and the
checks are unnecessary.
On the contrary the checks now prevented bigger packages to be moved
into the rx buffers.

This patch reverts the wrong checks and were sucessfully tested with a
qemu-system-hppa emulation.

Use for configuration the same procedure as already
used for RSS. We add two fields in rss_data that
controls what the device does with the calculated hash
if rss_data.enabled is set. If field 'populate' is set
the hash is set in the packet, if field 'redirect' is
