fixes on top of Florian's truncation detection ( 1ff299bc2)
...
* initialize `Size` with the then-size of the file when ChangeEvents
is called. remember that this function is expected to be called many
times, one after another. this also passes the TestReSeekInotify
test.
* do not ignore errors from os.Stat. we panic errors like these now,
but ideally should switch to tomb.Tomb for letting the user handle
them.

fix truncation tests
...
* use O_TRUNC to actually truncate
* use longer initial data before truncating
truncated and updated file is expected to be of smaller size, else
truncation detection won't work.
