dirstate: move the copymap drop inside dropfile

Since the copymap is part of the dirstatemap it make more sense for the
dirstatemap to manage it directly.

This is part of a generic effort to move unified logic at lower level and to
clean up higher level API.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
