METEORSSIGNAL ioctl. Applications use this ioctl with the value METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery, but revision 1.126 caused the driver to return EINVAL in this case. Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses 0 to reset signal delivery. This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the bktr driver, and restructures the code a bit so that it is otherwise identical between the bktr and meteor drivers.
