Current legacy floppy detection is hardcoded based on source file
name. Make this smarter on linux by attempting a floppy specific
ioctl.

v2:
    Give ioctl check higher priority than filename check

v3:
    Actually initialize 'prio' variable
    Check for ioctl success rather than absence of specific failure

v4:

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.

Implementation of points 1-3 allows booting Solaris 2.6 and 2.5.1.

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
"TARGET_LONG_BITS==64" check in syscall.c isn't enough.  Below is
a patch that fixes things for me, although it might not be the cleanest
fix.

According to RFC 1350 and RFC 2347, TFTP server should answer RRQ by
either OACK or DATA packet. Qemu's internal TFTP server answers RRQ with
additional options by sending both OACK and DATA packet, thus breaking
the "lock-step" feature of the protocol, and also confuses client.

  Proposed solution would be to, in case of OACK packet, wait for ACK
from client and just then start sending data. Attached patch implements
this.
