inotify: check all components of filenames against hgignore (issue884)

With inotify enabled, files that should be ignored could be detected as
untracked by mercurial. This behavior was wrong because inotify's filestatus
implementation only matched filenames against ignore patterns, instead of
checking if other elements of their paths matched them. This patch fixes the
behavior by checking the file paths against the ignore patterns.

A new test has also been added to the main inotify test to prevent any
regressions.
