convert: backout 81cf597dafa9 and a3545c3104aa -closemap

Closemap solves a very specific use case. It would be better to have a more
generic solution than to have to maintain this forever.

Closemap has not been released yet and removing it now will not break any
backward compatibility contract.

There is no test coverage for closemap but it seems like the same can be
achieved with a simple and much more powerful custom extension:

import hgext.convert.hg
class source(hgext.convert.hg.mercurial_source):
    def getcommit(self, rev):
        c = super(source, self).getcommit(rev)
