help: add internals.extensions topic
I think it's better to include the API overview in core as we now have the
internals section in our help system.
Retrieved from the wiki, and formatted as reST. Several wiki links are
removed since they are invalid in the help. The sections about example
extension are removed at all as they seemed too verbose.

For debugging: this is a pretty simple test that is a good candidate
for tracking down network-related bugs. Sometimes a command in this
hangs, so having showstack pre-loaded is sometimes helpful. This also
gives us a test that at least proves showstack can be loaded.
$ cat >> $HGRCPATH <<EOF
> [extensions]
> showstack = $TESTDIR/../contrib/showstack.py
