From armv6, the architecture supports unaligned accesses.
All we need to do is perform the correct alignment check

In the SSE decode function gen_sse(), we combine a byte
'b' and a value 'b1' which can be [0..3], and switch on them:
b |= (b1 << 8);
switch (b) {
...
default:
unknown_op:
gen_unknown_opcode(env, s);
return;
}
In three cases inside this switch, we were then also che

In sev_read_file_base64() we call g_file_get_contents(), which
allocates memory for the file contents. We then base64-decode the
contents (which allocates another buffer for the decoded data), but
forgot to free the memory for the original file data.
Use g_autofree to ensure that the file data is

g_setenv() can fail; check for it when starting a QEMU process
when we set the QEMU_AUDIO_DRV environment variable.
Because this happens after fork() reporting an exact message
via printf() is a bad idea; just exit(1), as we already do
for the case of execlp() failure.
