All callers of ide_create_drive() ignore its value.  Currently
harmless, because it fails only when qdev_init() fails, which fails
only when ide_drive_initfn() fails, which never fails.

Brittle.  Change it to die instead of silently ignoring failure.

None of its callers checks for failure.  scsi_hot_add() can crash
because of that:

(qemu) drive_add 4 if=scsi,format=host_device,file=/dev/sg1
scsi-generic: scsi generic interface too old
Segmentation fault (core dumped)

Fix all callers, not just scsi_hot_add().

Before the raw/file split we used to allow filenames with colons for host
device only.  While this was more by accident than by design people rely
on it, so we need to bring it back.

So move the host device probing to be before the protocol detection
again.

ssse3 uses tables with only two entries per op, but it is indexed
with b1 which can contain variables upto 3. This happens when ssse3

scanf calls must not use PRI constants, they have probably the wrong size and
corrupt memory. We could replace them by SCN ones, but strtol is simpler than
scanf here anyway. While at it, also fix the parsers to reject garbage after
the number ("4096xyz" was accepted before).

Commit 50e32ea8 changed the behaviour
for the return type of net_client_init() when a nic type with no init
method was specified. 'none' is one such nic type. Instead of returning
0, which gets interpreted as an index into the nd_table[] array, we
switched to returning -1, which signifies an error as well.

That broke VM start with '-net none'. Testing was only done with the
monitor command 'pci_add', which doesn't fail.

The correct fix would still be to return 0+ values from
net_client_init() only when the return value can be used as an index to
refer to an entry in nd_table[]. With the current code, callers can
erroneously poke into nd_table[0] when -net nic is used, which can lead
to badness.

However, this commit just returns to the previous behaviour before the
offending commit.

We currently only clear SVM_EVTINJ_VALID after successful interrupt
delivery. This apparently does not match real hardware which clears the
whole event_inj field on every vmexit, including unsuccessful interrupt
delivery.
