extensions: load and configure extensions in well-defined phases
Extensions are now loaded with a call-graph like this:
dispatch._dispatch
extensions.loadall
extensions.load
# add foo module to extensions._extensions
extensions.load
# add bar module to extensions._extensions
foo.uisetup(ui)
bar.uisetup(ui)
foo.extsetup()
bar.extsetup()
commands.table.update(foo.cmdtable)
commands.table.update(bar.cmdtable)
hg.repository
foo.reposetup(ui, repo)
bar.reposetup(ui, repo)
The uisetup calls could easily be moved out to dispatch._dispatch, but
have been kept in extensions.loadall since at least TortoiseHg calls
extensions.loadall and expects it to call uisetup.
The extensions.load function called uisetup. It now has an unused ui
argument which has been kept for backwards compatibility.
