pfl->wcycle was set to 1 when the erase confirm command was set, which
lead to the next command being misinterpreted by Qemu:
pflash_write: Unimplemented flash cmd sequence (offset 00000000,
wcycle 0x1 cmd 0x20 value 0x70)
This patch fixes this issue by resetting pfl->wcycle to 0 on erase
confirm so that the next command is considered as a new one.

This patch makes the ide emulation actually take notice of
error returns from bdrv_write and bdrv_aio_{read,write}.

To support live migration, we override QEMUFile so that instead of writing to
disk, the save/restore state happens over a network connection.
This patch makes QEMUFile read/write operations function pointers so that we
can override them for live migration.

This implements most of the logic of a real HCI (at least the pieces
marked as mandatory). It doesn't support keys, authentication etc.
It works on top of the LMP layer, which is not fully emulated because
software never has direct access to it.

This patch allows to use a "real" SCSI tape with qemu using
"-drive /dev/sgX,if=scsi".
It allows to decode correctly transfer length when the type of the
device is a tape.
Some issues remain when the application reading the tape tries to go
beyond the end of the stream (but they must be corrected at the SCSI
controller level).

Raise UDC (Unexpected Disconnect) when a large enough number of
instructions has been executed by the SCRIPTS processor. This "solution"
is much simpler than temporarily interrupting execution.
This remedies the situation with Windows which downloads SCRIPTS code
that busy loops on guest main memory. Their drivers _do_ handle UDC
appropriately (at least XP and 2003).
It would be nicer to actually detect infinite loops, but until then,
this bandaid seems acceptable.
Since the situation seems to be rare enough, raise the number
of instructions to 10000 (previously 1000).
Three people other than myself had success with this patch.

According to linux kernel sources, register a3 is set in case of failure
(and cleared in case of success) while register v0 contains the result
(or -errno in case of error).
The convention was not followed which results in weird behaviour.

* Remove the unused send_buf variable and its constant.
* Fix a math error
The variables recv_ptr and recv_used are not large enough to hold
the constant 384, which causes data corruption when the pointer is
reset with: s->recv_ptr = (s->recv_ptr + len) % RECV_BUF;
