zev: zevadm now uses tmpqueue as a default for polling

zevadm poll mode used to create a non-persistent queue to receive
events. The new tmpqueue device is now used instead. Functionality
remains the same. However, the tmpqueue will always be empty when
created, while the old method allowed the option of seeing older
zev events in the new queue, if available. This was rarely useful,
though, and can still be done by creating an explicit persistent queue
first.

In -p mode without a queue, a temporary queue is created to poll for current

desired to peek at the oldes event still queued, which can be done with the
combination of -p and -E.

zevadm: make temporary queue non-blocking and initially empty

When zevadm is used without -q, a temporarily created queue is used. The
normal use case of this call is debugging current events. The stream of
events should start after the call to zevadm -p, hence the shift to the
initlally empty flag. Debugging should not lead to blocking systems, no
matter how slow the events are printed to the reader's terminal, hence the
non-blocking flag.

New zev queues where filled with as many events as would fit from

The new queue will then be empty upon creation and will only receive

zev: create and symlink events now inlude checksum

When a symlink or another new file is created, the resulting
zev events now include a signature for the new file.

Symlinks are treated like files that contain the "link" part
as text. Block and character devices have a signature based
on the format string "%c%d,%d", with 'b'/'c', getmajor() and
getminor() as values. All other file types will result in an
all-zero signature.

Hardlinks create a new directory entry, but no new inode.
Therefore, rdlink events still do not contain a signature.
