New microcode introduces the "Speculative Store Bypass Disable"
CPUID feature bit. This needs to be exposed to guest OS to allow
them to protect against CVE-2018-3639.

use the better wording "dropped in" instead of "removed with" (also

In gdb_accept(), we both fail to check all errors (notably
that from socket_set_nodelay(), as Coverity notes in CID 1005666),
and fail to return an error status back to our caller. Correct
both of these things, so that errors in accept() result in our
stopping with a useful error message rather than ignoring it.

Use the utility routine qemu_set_cloexec() rather than
manually calling fcntl(). This lets us drop the #ifndef _WIN32
guards and also means Coverity doesn't complain that we're
ignoring the fcntl error return (CID 1005665, CID 1005667).

Currently the minimal supported version of glib is 2.22.
Since testing is done with a glib that claims to be 2.22, but in fact
has APIs from newer version of glib, this bug was not caught during
submit of the patch referenced below.
Replace g_realloc_n, which is available only since 2.24, with g_renew.

After 1217d6ca2b we error out
explicitly if an unknown -option was passed on the command line.
However, we are doing two pass command line option parsing. In
the first pass we just look for -no-user-config or -nodefconfig
being present which determines whether we load user config or
not. Then in the second pass we finally parse everything else
throwing an error if an unsupported -option was found. Problem is
that in the second pass -no-user-config and -nodefconfig are not
handled explicitly which makes us throw the unsupported option
error.
