It's emitted when a VNC client connects to QEMU, client's information
such as port and IP address are provided.

Note that this event is emitted right when the connection is
established. This means that it happens before authentication
procedure and session initialization.

Event example:

{ "event": "VNC_CONNECTED",
    "timestamp": { "seconds": 1262976601, "microseconds": 975795 },
    "data": {
        "server": { "auth": "sasl", "family": "ipv4",
                    "service": "5901", "host": "0.0.0.0" },
        "client": { "family": "ipv4", "service": "58425",
                    "host": "127.0.0.1" } } }

When a disconnection happens the client's socket on QEMU
side may become invalid, this way it won't be possible
to query it to get client information, which is going to
be needed by the future QMP VNC_DISCONNECTED event.

To always have this information available we query the
socket at connection time and cache the client info in
struct VncState.

Two function are introduced to perform this job.

vnc_client_cache_addr() is called right when the connection
is made, however the authentication information is not
available at that moment so vnc_client_cache_auth() is
called from protocol_client_init() to get auth info.

Handling of transmit commands is rather complex,
so about 80 lines of code were moved from function
action_command to the new function tx_command.

The two new values "tx" and "cb_address" in the
eepro100 status structure made this possible without
passing too many parameters.

In addition, the moved code was cleaned a little bit:
old comments marked with //~ were removed, C++ style
comments were replaced by C style comments, C++ like
variable declarations after code were reordered.

Simplified mode is still broken. Nor did I fix
endianess issues. Both problems will be fixed in
additional patches (which need this one).

According to pages 9-31 - 9-34 of "SuperSPARC & MultiCache Controller
User's Manual":

1. "A lower priority fault may not overwrite the
    MFSR status of a higher priority fault."
2. The MFAR is overwritten according to the policy defined for the MFSR
3. The overwrite bit is asserted if the fault status register (MFSR)
   has been written more than once by faults of the same class
4. SuperSPARC will never place instruction fault addresses in the MFAR.

The existing P_REXB internal opcode flag unconditionally emits
the REX prefix.  Technically it's not needed if the register in
question is %al, %bl, %cl, %dl.

Eliding the prefix requires splitting the P_REXB flag into two,
in order to indicate whether the byte register in question is
in the REG or the R/M field.  Within TCG, the byte register is
in the REG field only for stores.

The stat64/fstat64 syscalls are broken for alpha linux-user.

This is because Alpha, even though it is native 64-bits, has a stat64
syscall that is different than regular stat.  This means that the
