fix problems with external module handling. found by benoit boissinot.
first fix is to not store module objects in commands.external dict,
instead use module names for key into sys.modules. this prevents circular
reference during cleanup of aborted transaction.
second is to get name right during import of external module.
#!/bin/sh
#
# A B
#
# 3 4 3
# |\/| |\
# |/\| | \
# 1 2 1 2
# \ / \ /
# 0 0
#
# if the result of the merge of 1 and 2
# is the same in 3 and 4, no new manifest
# will be created and the manifest group
# will be empty during the pull
#
# (plus we test a failure where outgoing
# wrongly reported the number of csets)
