This fixes the following scenario using QMP.
First, put a bogus argument "foo" to "type", which results in an error.
{"execute": "netdev_add", "arguments": { "type": "foo", "id": "netdev1" } }
Then, call it again with correct argument "user".
{"execute": "netdev_add", "arguments": { "type": "user", "id": "netdev1" } }
This results in "DuplicatedId" error.
Because the first command was invalid, it should be able to reuse the
same "id", and the second command should work.

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

Commit 50e32ea8f3 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.

lsi_bad_phase has a bug in the choice of pmjad1/pmjad2. This does
not matter with Linux guests because it uses just one routine for
both, but it breaks Windows 64-bit guests. This is the text
from the spec:
"[The PMJCTL] bit controls which decision mechanism is used
when jumping on phase mismatch. When this bit is cleared the
LSI53C895A will use Phase Mismatch Jump Address 1 (PMJAD1) when
the WSR bit is cleared and Phase Mismatch Jump Address 2 (PMJAD2)
when the WSR bit is set. When this bit is set the LSI53C895A will
use jump address one (PMJAD1) on data out (data out, command,
message out) transfers and jump address two (PMJAD2) on data in
(data in, status, message in) transfers."
Which means:
CCNTL0.PMJCTL
0 SCNTL2.WSR = 0 PMJAD1
0 SCNTL2.WSR = 1 PMJAD2
1 out PMJAD1
1 in PMJAD2
In qemu, what you get instead is:
CCNTL0.PMJCTL
0 out PMJAD1
0 in PMJAD2 <<<<<
1 out PMJAD1
1 in PMJAD1 <<<<<
Considering that qemu always has SCNTL2.WSR cleared, the two marked cases
(corresponding to phase mismatch on input) are always jumping to the
wrong PMJAD register. The patch implements the correct semantics.

the meaning of vendor_override is actually the opposite of how it
is currently used :-(
Fix it to allow KVM to export the non-native CPUID vendor if
explicitly requested by the user.
The intended behavior is:
With TCG:
- always inject the configured vendor (either hard-coded, in config
files or via ",vendor=" commandline)
With KVM:
- by default inject the host's vendor
- if the user specifies ",vendor=" on the commandline, use this
instead of the host's vendor
- all pre-configured vendors (hard-coded, config file) are ignored

mingw32 does not include function ffs.
Commit c6d29ad6e2 added a
declaration for ffs, but an implementation was missing.
For compilations with optimization, the compiler creates
inline code, so the implementation is not always needed.
Without optimization, linking fails without this patch.
