changegroup: deduplicate 'getlocalchangegroup'
The two functions 'getlocalchangegroup' and 'getchangegroup' have been strictly
identical for multiple years ('getchangegroup' had a deprecated docstring)
We'll drop one of them (getlocalchangegroup, since it has the longest name).
However, we needs to migrate all users of the dropped one to the new one before
we can deprecate it. In the mean time we drop one of the duplicated definition
and the outdated docstring.
