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.

# Note that this will cause your .hgrc files to be interpreted in
# UTF-8 and all your repo files to be displayed using UTF-8.

# The config file looks like this.  You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path1 = /real/path1
# virtual/path2 = /real/path2
# virtual/root = /real/root/*
# / = /real/root2/*
# virtual/root2 = /real/root2/**
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# paths example: 
#
# * First two lines mount one repository into one virtual path, like
# '/real/path1' into 'virtual/path1'.
#
# * The third entry mounts every mercurial repository found in '/real/root'
# in 'virtual/root'. This format is preferred over the [collections] one,
# since using absolute paths as configuration keys is not supported on every
# platform (especially on Windows).
#
# * The fourth entry is a special case mounting all repositories in
# /'real/root2' in the root of the virtual directory.
#
# * The fifth entry recursively finds all repositories under the real root,
# and mounts them using their relative path (to given real root) under the
# virtual root.
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz.  Give this config section:
#   [collections]
#   /foo = /foo
# Then repos will list as bar and quux/baz.
#
# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
