Allow uhidev child devices to claim selective report ids

There may be multiple matching devices on a single uhidev device but
the first device that responds to UHIDEV_CLAIM_ALLREPORTID will
block the others from attaching.

Change this to UHIDEV_CLAIM_MULTIPLE_REPORTID and require any
devices wanting some/all report ids to fill in the claimed array in
uhidev_attach_arg with just the reports it needs. uhidev can then
run match routines for other drivers with the available report ids.

Treat non-0 value as true for boolean indicators.

Makes sensorsd(8) happy with UPS reporting a value of "-1" for true.

Reported by and initial diff from Boudewijn Dijkstra.

A pile of sizes to free(9). In test for a few days in snapshots.
Errors will result in nice clean panic messages so we know what's wrong.

Link report descriptors to known sensors.

Since HID buffers always start by a reportID we can access the corresponding
report descriptor in O(1). Having a list of sensors attached to each report
descriptor makes it easier to update all of them with only on I/O request.

Note that sensors are attached in depency order on every report list.

Change uhidev(4) set/get report functions in various way.

Always pass the parent uhidev(4) descriptor corresponding to the single
USB device with multiple reportIDs instead of a child.

Make uhidev_get_report() aware of non NUL reportID by prepending a byte
to the given buffer, just like uhidev_set_report{,async}() already do.

Return the number of bytes written or read upon success and -1 otherwise.
This allow callers to deal with short reads without having do mess with
xfer error codes madness.
