rG947739079604: hid: Import hidraw(4) - driver for access to raw HID device data

Summary

This driver provides raw access to HID devices through uhid(4)-compatible interface and is based on pre-8.x uhid(4) code.

Unlike uhid(4) it does not take devices in to monopoly ownership and allows parallel access from other drivers.
hidraw supports Linux's hidraw-compatible interface as well.

Also this change adds HIDRAW_MAKE_UHID_ALIAS kernel option which installs /dev/uhid# alias to hidraw character device for compatibility with some existing uhid(4) users like Firefox.
As side effect enabling of this option renames traditional uhid(4) driver to hidraw to make possible using of common unit number allocator.
