Markus Armbruster pointed out:
JSON requires control characters in strings to be escaped. RFC 4627
section 2.5:
A string begins and ends with quotation marks. All Unicode
characters may be placed within the quotation marks except for the
characters that must be escaped: quotation mark, reverse solidus, and
the control characters (U+0000 through U+001F).
We've been quoting the special escape sequences that JSON defines but we
haven't been encoding the full control character range. This patch fixes that.

A new option, -nodefconfig is introduced to prevent loading from the default
config location. Otherwise, two configuration files will be searched for,
qemu.conf and target-<TARGET_NAME>.conf.
To ensure that the default configuration is overridden by a user specified
config, we introduce a two stage option parsing mechanism.

Commit 930c86820e introduced a regression to eth_send: eth_tx_desc_put
manipulates the host's tx descriptor copy before writing it back, but
two lines down the descriptor is evaluated again, leaving us with an
invalid next address if host and guest endianness differ. So this was
the actual issue commit 2e87c5b937 tried to paper over.

Commit f039a563f2 introduces
a regression as monitor_protocol_event() will return in
the first user Monitor it finds in the QLIST_FOREACH()

The right thing to do is to only delivery an asynchronous
