esp.c: don't raise INTR_BS interrupt in DATA IN phase until TI command issued
In the case where a SCSI command with a DATA IN phase has been issued, the host
may preload the FIFO with unaligned bytes before issuing the main DMA transfer.
When accumulating data in the FIFO don't raise the INTR_BS interrupt until the
TI command is issued, otherwise the unexpected interrupt can confuse the host.
In particular this is needed to prevent the MacOS Disk Utility from failing
when switching non-DMA transfers to use esp_do_nodma().

esp.c: remove unneeded ti_cmd field
According to the datasheet the previous ESP command remains in the ESP_CMD
register, which caused a problem when consecutive TI commands were issued as
it becomes impossible for the state machine to know when the first TI
command finishes.
This was the original reason for introducing the ti_cmd field which kept
track of the last written command for this purpose. However closer reading
of the datasheet shows that a TI command that terminates due to a change of
SCSI target phase resets the ESP_CMD register to zero which solves this
problem.
Now that this has been fixed in the previous commit, remove the unneeded
ti_cmd field and access the ESP_CMD register directly instead. Bump the
vmstate_esp version to indicate that the ti_cmd field is no longer included.

Note that SeaBIOS-hppa v16 provides the "-fw_cfg opt/OS64,string=3" option with

qapi: Require member documentation (with loophole)
The QAPI generator forces you to document your stuff. Except for
command arguments, event data, and members of enum and object types:
these the generator silently "documents" as "Not documented".
We can't require proper documentation there without first fixing all
the offenders. We've always had too many offenders to pull that off.
Right now, we have more than 500. Worse, we seem to fix old ones no
faster than we add new ones: in the past year, we fixed 22 ones, but
added 26 new ones.
To help arrest the backsliding, make missing documentation an error
unless the command, type, or event is in listed in new pragma
documentation-exceptions.
List all the current offenders: 117 commands and types in qapi/, and 9
in qga/.
