zevadm: bugfixes for zevstat mode

Draining the new queue was done until poll() with a one
second timeout return 0. On busy systems this never happens.
Now poll() without a timeout must return 0.

When called as zevstat, giving no interval parameter caused a
core dump.

zevadm: bugfix with option parsing

Option parsing was order dependent. For example, "-p -v" ignored
the "-v" option while "-v -p" worked. Order does not matter
anymore.

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.

zev: ioctl() to get signatures for an open file

There's a new ioctl() ZEV_IOC_GET_FILE_SIGNATURES to get
beaver signatures for a data range in an open file. The
provided buffer has to be large enough to hold the parameters
and the signatures.

zevadm can display a file's signatures using 'zevadm -c <filename>'

zev: calculate beaver-compatible checksums of changes

Ranges required to calculate the checksums will be range locked before
the zev callbacks are called. Checksums are calculated in the zev
module and reported to userland. Checksums of all-zeroes blocks are
omitted. Userland is expected to infer that the block must have bee
all-zeroes.

An internal cache is implemented to avoid re-reading the same data
over and over again.
