I'll move createservice() to the server module, but createapp() seems good to
remain in the hgweb module because of its dependency on hgweb/hgwebdir_mod.
Before this patch, it was unclear why the httpservice object could read the
server options (e.g. --port) from 'ui'. It just worked because repo.ui is ui.
Since createservice() was moved to hgweb and hgweb imports both hgweb_mod and
hgwebdir_mod, we no longer have to force hgweb() function to select one of
them by the type of 'o' variable. Let's be explicit!
This patch does not change hgweb() function because it is the interface of
existing WSGI and CGI scripts.
The next patch will merge the cmdutil.service() calls of both commandserver
and hgweb. Before doing it, this patch wipes out the code specific to hgweb
from commands.serve().
In the v4l-dvb repo, the manifest revno and the changelog revno are not
in sync. This happened because the same patch was applied to the same
revision in two different branches, resulting in the same manifest text,
with the same parents and so the first revision was reused.
Since hgweb.manifest was assuming the revnos of the manifest and of the
changelog were always the same, clicking on manifest -> bz2 in the
v4l-dvb site would download the wrong revision.
Use the linkrev to go from manifest revision to changelog revision.
This still won't be perfect since the page will still talk about
"manifest for changeset XYZ", where XYZ was the first changeset to have
this manifest, which is not necessarily the same changeset that the user
clicked to get to this page - but at least the contents will be the
same.
