Set BTN_TOUCH, BTN_TOOL_DOUBLETAP automatically depending on the number of
fingers down.
This emulates real event sequences a bit better than the current approach,
though it's not a 100% correct emulation:
1) On real devices, BTN_* are usually sent last before the SYN_REPORT - here
they are sent first to slot in with the custom, device-specific event
sequence. We should only ever look at the complete sequence anyway, so this
shouldn't matter.
2) On real devices, the switch from BTN_TOOL_DOUBLETAP to TRIPLETAP and vice
versa is not always toggled within the same SYN_REPORT
3) On synaptics devices, BTN_TOUCH is released in the frame where
BTN_TOOL_DOUBLETAP is set. It is then immediately set again in the next
frame. With the current litest framework this is hard to integrate, so we
just leave BTN_TOUCH set the whole time, which is what MT devices do if
they don't have BTN_TOOL_DOUBLETAP.

struct input_absinfo has the resolution as the 6th field, not as the 4th.
This doesn't have any visible effect because uinput doesn't allow us to set
the resolution yet.

Both functions accept a series of event types/codes tuples, terminated by -1.
For the even type INPUT_PROP_MAX (an invalid type otherwise) the code is used
as a property to enable.
The _abs function als takes an array of absinfo, with absinfo.value
determining the axis to change. If none are given, abs axes are initialized
with default settings.
Both functions abort on failure, so the caller does not need to check the
return value.
Example code for creating a rel device:
struct libevdev_uinput *uinput;
struct input_id id = { ... };
uinput = litest_create_uinput_device("foo", &id,
EV_REL, REL_X,
EV_REL, REL_Y,
EV_KEY, BTN_LEFT,
INPUT_PROP_MAX, INPUT_PROP_BUTTONPAD,
-1);
libevdev_uinput_write_event(uinput, EV_REL, REL_X, -1);
libevdev_uinput_write_event(uinput, EV_SYN, SYN_REPORT, 0);
...
libevdev_uinput_destroy(uinput);
