Pavel Dovgaluk c3febae62b Fixing tap adapter for win32
This fix allows connection of internal VLAN to the external TAP interface.
If tap_win32_write function always returns 0, the TAP network interface
in QEMU is disabled.

Blue Swirl 49a2942d9b Delete write only variables
Compiling with GCC 4.6.0 20100925 produced warnings like:
/src/qemu/net/tap-win32.c: In function 'tap_win32_open':
/src/qemu/net/tap-win32.c:582:12: error: variable 'hThread' set but not used [-Werror=unused-but-set-variable]

Fix by removing the unused variables.

Markus Armbruster 1ecda02b24 error: Replace qemu_error() by error_report()
error_report() terminates the message with a newline.  Strip it it
from its arguments.

This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for
IFF_VNET_HDR available" (all three versions).

There's one place that passes arguments without newlines
intentionally: load_vmstate().  Fix it up.

Markus Armbruster 62112d181c net: Fix bogus "Warning: vlan 0 with no nics" with -device
net_check_clients() prints this when an VLAN has host devices, but no
guest devices.  It uses VLANState members nb_guest_devs and
nb_host_devs to keep track of these devices.  However, -device does
not update nb_guest_devs, only net_init_nic() does that, for -net nic.

Check the VLAN clients directly, and remove the counters.
