Message:

input server improvements

• integrate legacy port mouse drivers (PS/2, ADB) into the input server (to be on par with the legacy keyboard drivers)
• create generic port/protocol layers for the mouse in the input server
• rename the "hid_in" namespace to "hid" namespace (hid_in/input was rather redundant)
• rename the mouse event IPC messages to be more consistent with the keyboard event messages
• rename input server ops structure members to be more generic (parse_scancode → parse)
• cstyle changes (newlines, comments, printouts)
