When using -net user,guestfwd=... Qemu immediately complains about the id
being in invalid format. This is because we pass in an id that contains a
colon, while the id restrictions don't allow colons.
This patch changes the colon into a dot, making guestfwd work again.

This patch adds a dummy legacy ISA device whose responsibility is to

The proposal is that this device is always-on when -nographics,
but can otherwise be enable in any setup when -device sga is used.

This allows a JSON_ERROR state to be passed to the streamer to force a
flush of the current tokens and pass a NULL token list to the parser
rather that have it churn on bad data. (Alternatively we could just not
pass it to the parser at all, but it may be useful to push there errors
up the stack. NULL token lists are not currently handled by the parser,
the next patch will address that)

Currently when we reach an error state we effectively flush everything
fed to the lexer, which can put us in a state where we keep feeding
tokens into the parser at arbitrary offsets in the stream. This makes it
difficult for the lexer/tokenizer/parser to get back in sync when bad
input is made by the client.
With these changes we emit an error state/token up to the tokenizer as
soon as we reach an error state, and continue processing any data passed
in rather than bailing out. The reset token will be used to reset the
tokenizer and parser, such that they'll recover state as soon as the
lexer begins generating valid token sequences again.
We also map chr(192,193,245-255) to an error state here, since they are
invalid UTF-8 characters. QMP guest proxy/agent will use chr(255) to
force a flush/reset of previous input for reliable delivery of certain
events, so also we document that thoroughly here.

Currently we flush the lexer by passing in a NULL character. This
generally forces the lexer to go to the corresponding TERMINAL() state
for whatever token type it is currently parsing, emits the token to the
parser, then puts the lexer back into IN_START state. However, since a
NULL character causes char_consumed to be 0, we always do a second pass
after this, which puts us in the IN_ERROR state. Fix this behavior by
adding a "flush" flag that tells the lexer not to do a more than 1
iteration.

Commit 85097db6 changed the timing when kvm_allowed is set until after
kvm is initialized. During initialization, the ioeventfd initialization code
checks kvm_enabled() and after this change, ioeventfd is effectively disabled.
This causes a significant regression in performance.
Fix this by setting kvm_allowed before calling init.

from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to

than only if compiling on a host system with the other word size.
