[evdev] Use proper mutex reference in autorepeat callout initialization. This fixes panic occuring when evdev key autorepeat is enabled by driver which initializes evdev with external mutex.

evdev: Add COMPAT_FREEBSD32 support for amd64 arch Incompatibility between i386 and amd64 evdev ABIs was caused by presence of 'struct timeval' in evdev protocol. Replace it with 'struct timeval32' for 32 bit binaries. Big-endian platforms may require additional work due to bitstr_t (array of unsigned longs) usage in ioctl interface. MFC r359429: evdev: return error rather than zero-length data on blocked read() if blocked process has been woken up by evdev device destruction.

evdev: export event device properties through sysctl interface A big security advantage of Wayland is not allowing applications to read input devices all the time. Having /dev/input/* accessible to the user account subverts this advantage. libudev-devd was opening the evdev devices to detect their types (mouse, keyboard, touchpad, etc). This don't work if /dev/input/* is inaccessible. With the kernel exposing this information as sysctls (kern.evdev.input.*), we can work w/o /dev/input/* access, preserving the Wayland security model.

T-axis buttons state should be checked by level not by edge to allow continuous wheel tilt reporting MFC r325298: evdev: Disable value normalization and state filtering for SND events. Some events can take sound pitch as a value so can not be represented as binary on/off events. Tracking for on/off state is left in place as it is a part of the evdev API.
