utils: Introduce IsBelowDir

This is mainly a wrapper to overcome the limitation of commonprefix
which makes a string by string comparisation and reports the common
prefix in both strings. However this is bad for directory handling.

IsBelowDir works around this limitation and should be used in favour of...

This will be used by the watcher to store the file's fstat(2). It must
be done from the filehandle.

Fix WriteFile with unicode data

Unicode is fun, indeed:

len(buffer(u"abc"))

Fix potential data-loss in utils.WriteFile

os.write can do incomplete writes, as long as at least some bytes have

os.write(fd, " " * 1300)

1300

os.write(fd, " " * 1300)
