dirs: speed up by storing number of direct children per dir
The Python version of the dirs type stores only the number of direct
children associated with each directory. That means that while adding
a directory, it only has to walk backwards until it runs into a
directory that is already in its map. The C version walks all the way
to the top-most directory. By copying the Python version's clever
trick to the C code, we can speed it up quite a bit.
On the Firefox repo, perfdirs now runs in 0.031390, from 0.056518
before the undoing Sid's optimization in the previous change, and
0.061835 before previous his optimization. More practically, it speeds
up 'hg status nonexistent' on the Firefox repo from 0.176s to 0.155s.
It's unclear why the C version did not have the same cleverness
implemented from the start, especially given that they were both
written by the same person (Bryan O'Sullivan) very close in time:

"""hooks for integrating with the CIA.vc notification service
This is meant to be run as a changegroup or incoming hook. To
configure it, set the following options in your hgrc::
[cia]
# your registered CIA user name
user = foo
# the name of the project in CIA
project = foo
# the module (subproject) (optional)
#module = foo
# Append a diffstat to the log message (optional)
#diffstat = False
# Template to use for log messages (optional)
#template = {desc}\\n{baseurl}{webroot}/rev/{node}-- {diffstat}
# Style to use (optional)
#style = foo
# The URL of the CIA notification service (optional)
# You can use mailto: URLs to send by email, e.g.
# mailto:cia@cia.vc
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False
# number of slashes to strip for url paths

# one of these:
changegroup.cia = python:hgcia.hook
#incoming.cia = python:hgcia.hook
[web]
