Rebasing against upstream after the input directory move.

Additionally there are two patches from Vinicius to improve re-connection time,
only discovering characteristics when probing the HoG device.

Claudio Takahasi (4):
  hog: Use real values for vendor and product IDs
  hog: Add read Report Reference descriptor
  hog: Add HID Information Characteristic read
  hog: Use hardware country code

João Paulo Rechi Vita (6):
  hog: HID I/O driver
  hog: Prepend Report ID to the HID report
  hog: Add support for uHID events
  hog: Handle output reports
  hog: Handle output events
  hog: Handle feature reports

Paulo Alcantara (1):
  hog: Handle HID devices operating in Boot Protocol Mode

Vinicius Costa Gomes (2):
  hog: Fix re-discovering HoG characteristics when reconnecting
  hog: Fix destroying the uhid device when disconnecting

uHID is HID I/O driver that makes possible to implement HID I/O drivers in
user-space. It works similar to the uinput but it is initialized with a HID
descriptor and deals with raw HID reports.

This commit uses uHID to create a HID device for the remote HoG device and
to tranfers HID reports to HID subsystem.

This patch replaces the hard-code values for vendor and product IDs
by the values obtained from the device core functions. Vendor and
product IDs are read from the remote's Device Information Service.

This patch adds the GATT operation to read the value of the Report
Reference descriptor of the Report characteristic.

If the report descriptor has a Report ID tag it has to be prepended
to the report data to construct the HID report itself.

BlueZ does not support HID devices operating in Boot Protocol Mode, so we
need to set it back to Report Protocol Mode through the Protocol Mode
characteristic.

This patch takes cares of changing from Boot Protocol Mode to Report
Protocol Mode by writing the Protocol Mode characteristic value to 1,
which is value for Report Protocol Mode on HID devices operating in
Boot Protocol Mode.

If the reports list is already present there's no need rediscovering all
the characteristics. This should also make reconnections faster.

The uhid device should have the lifetime of the hog_device structure.
So, only destroy the uhid device when hog_device is destroyed.

uHID is HID I/O driver that makes possible to implement HID I/O drivers in
user-space. It works similar to the uinput but it is initialized with a HID
descriptor and deals with raw HID reports.

This commit uses uHID to create a HID device for the remote HoG device and
to tranfers HID reports to HID subsystem.
