5ecfb76ccc configure: fix detection of gdbus-codegen
"pkg-config --variable=gdbus_codegen gio-2.0" returns "gdbus-codegen",
and it does not pass test -x (which does not walk the path).

Meson 0.58.0 notices that something is iffy, as the dbus_vmstate1
assignment in tests/qtest/meson.build uses an empty string as the
command, and fails very eloquently:

../tests/qtest/meson.build:92:2: ERROR: No program name specified.

Use the "has" function instead of test -x, and fix the generation
of config-host.mak since meson.build expects that GDBUS_CODEGEN
is absent, rather than empty, if the tool is unavailable.

f8ce39701b bsd-user: Stop building the sparc targets
The forked bsd-user tree doesn't really support these targets.  They aren't
functional at the moment anyway. Remove them from the build so that the major
reorg patch series can focus on one platform (x86) before adding addition
platforms once things are shuffled. This should make it easier to review and
satisfy that all revisions of a patch series are buildable.

37179e9ea4 sockets: update SOCKET_ADDRESS_TYPE_FD listen(2) backlog
socket_get_fd() fails with the error "socket_get_fd: too many
connections" if the given listen backlog value is not 1.

Not all callers set the backlog to 1. For example, commit
582d4210eb2f2ab5baac328fe4b479cd86da1647 ("qemu-nbd: Use SOMAXCONN for
socket listen() backlog") uses SOMAXCONN. This will always fail with in
socket_get_fd().

This patch calls listen(2) on the fd to update the backlog value. The
socket may already be in the listen state. I have tested that this works
on Linux 5.10 and macOS Catalina.

As a bonus this allows us to detect when the fd cannot listen. Now we'll
be able to catch unbound or connected fds in socket_listen().

Drop the num argument from socket_get_fd() since this function is also
called by socket_connect() where a listen backlog value does not make
sense.

Fixes: e5b6353cf25c99c3f08bf51e29933352f7140e8f ("socket: Add backlog parameter to socket_listen")

6baba30ad0 target/riscv: Consolidate RV32/64 16-bit instructions
This patch removes the insn16-32.decode and insn16-64.decode decode
files and consolidates the instructions into the general RISC-V
insn16.decode decode tree.

This means that all of the instructions are avaliable in both the 32-bit
and 64-bit builds. This also means that we run a check to ensure we are
running a 64-bit softmmu before we execute the 64-bit only instructions.
This allows us to include the 32-bit instructions in the 64-bit build,
while also ensuring that 32-bit only software can not execute the
instructions.

3a7f7757ba fpu/softfloat: set invalid excp flag for RISC-V muladd instructions
In IEEE 754-2008 spec:
  Invalid operation exception is signaled when doing:
  fusedMultiplyAdd(0, Inf, c) or fusedMultiplyAdd(Inf, 0, c)
  unless c is a quiet NaN; if c is a quiet NaN then it is
  implementation defined whether the invalid operation exception
  is signaled.

In RISC-V Unprivileged ISA spec:
  The fused multiply-add instructions must set the invalid
  operation exception flag when the multiplicands are Inf and
  zero, even when the addend is a quiet NaN.

This commit set invalid operation execption flag for RISC-V when
multiplicands of muladd instructions are Inf and zero.
