Compile with -Wall now. Add evdev.h to the sources so that make distcheck

    gets it.
Bugzilla #5943 <https://bugs.freedesktop.org/show_bug.cgi=5943> Make sure
    we include errno.h.
Reduce EVDEV_MAXBUTTONS to 96.
Split up evdevStateRec into a struct with pointers to new structs for btn,
    abs, rel, and key.
New structure type for handling the device capability bitmaps.
Add device bits and struct input_id to evdevDeviceRec.
Add matching device bits, struct input_id, and pass number to
    evdevDriverRec.
Prototype for evdevGetBits from evdev_brain.c.
Conversion for the evdevStateRec split.
Remove the errno.h include, it's in evdev.h for now.
Move the bit getting from the drivers to here, into evdevDeviceRec.
Fix a rare case of fd leakage.
Add several new (and somewhat ugly) device matching options: <map>Bits:
    Where map is one of ev, key, rel, abs, msc, led, snd, or ff. In the
    format of '+0 +3 -1-2 ~5-10', requires bits 0 and 3 be set, bits 1 and
    2 to not be set, and at least one bit in the range of 5 to
10 be set. bustype, vendor, product, and version: Simple integer options
    for matching the struct device_id fields, must be 0 (the default) or
    the exact value you wish to match against. pass: Bounded to 0-3,
    devices are matched to the first matching entry found, order for
    multiple matching entries in the same pass is undefined, but it starts
    with pass 0 and goes to pass 3.
Adaptation for the evdevStateRec split and the change in capability bitmap
    handling.
Add evdevGetBits to fill the new evdevBitsRec struct type.
Lots of somewhat ugly code for matching by capability bits.
Split out of evdevRescanDevices to smaller handling functions. The new
    design should be better if I decide to handle arbitrary Device fields
    again.
Adaptation for the evdevStateRec split and the change in capability bitmap
    handling.
Handle all buttons, no button compression at this time, however we reorder
    things so that BTN_MOUSE comes before BTN_MISC, somewhat evily.
Support for the new btn->state[] array of int pointers.
Adaptation for the evdevStateRec split and the change in capability bitmap
    handling.
Adaptation for the evdevStateRec split and the change in capability bitmap
    handling.
I really hope I didn't miss any changes.
