Rename from LIBEVDEV_READ_foo to LIBEVDEV_READ_FLAG_foo to differentiate
better from LIBEVDEV_READ_STATUS_foo.

Improved readability in callers, changing magic numbers 0 and 1 to
rc = libevdev_next_event();
if (rc == LIBEVDEV_READ_STATUS_SUCCESS)
do_something();
else if (rc == LIBEVDEV_READ_STATUS_SYNC)
do_something_else()
No ABI changes, the enum values are the previously documented values,
this is just a readability improvement.

This way any ABS_MT_ event value that comes in will also be stored in abs_info.
That always corresponds to "current slot", so if a user calls
libevdev_set_event_value() or libevdev_get_event_value() they're actually
modifying the current slot value.
When the current slot changes, sync the state back into the absinfo values.

This enables libevdev_get_event_value(dev, EV_LED, LED_NUML); to check
if a LED is on or off.
