inotify: fix issue1375, add a test.

The biggest problem was the data structure, which did not allow changing
a file into a directory or vice versa. This problem is fixed by b55d44719b47.

The walk() method also had an issue in this case:
 - we know 'path' as a directory. inotify server sleeps.
 - 'path' is deleted
 - 'path' is recreated as a file
 - the server catches up here, and see the deletion. it instantiates a scan(),
   which in its turn calls for walk(repo, path).
 - walk() then assumes that 'path' is a directory and calls os.listdir on it,
   which raises an OSError(errno.ENOTDIR)

Catch the error, and yield the file instead of the directory contents.

import os, sys
from mercurial import hg, ui

TESTDIR = os.environ["TESTDIR"]

# only makes sense to test on os which supports symlinks
if not hasattr(os, "symlink"):
    sys.exit(80) # SKIPPED_STATUS defined in run-tests.py

# this is what symlink would do on a non-symlink file system
def symlink_failure(src, dst):
    raise OSError, (1, "Operation not permitted")
os.symlink = symlink_failure

# now try cloning a repo which contains symlinks
u = ui.ui()
hg.clone(u, os.path.join(TESTDIR, 'test-no-symlinks.hg'), 'test1')
