inotify: don't fall over just because of a dangling symlink

Previously, the inotify server failed to start if .hg/inotify.sock was
a symlink that pointed to a non-existent path. This behaviour does not
seem to make any sense.

Now, if we encounter a broken symlink, we unlink it and continue.

import sys

globalvars = {}
localvars = {}
lines = sys.stdin.readlines()
while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print l[:-1]
    elif l.startswith('>>> '):
        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += "\n" + l[4:]
        c = compile(snippet, '<heredoc>', 'single')
        try:
            exec c in globalvars, localvars
        except Exception, inst:
            print repr(inst)
