releasenotes: improve parsing around bullet points

Earlier, on parsing the bullet points from existing release notes the bullet
points after the first one weren't written correctly to the notes file. This
patch makes changes to parsereleasenotesfromfile() function that introduces a new
bullet_points data structure that tracks the bullets and associated subparagraph.
It also makes necessary changes to the tests related to merging of bullets.

# extension to emulate invoking 'dirstate.write()' at the time
# specified by '[fakedirstatewritetime] fakenow', only when
# 'dirstate.write()' is invoked via functions below:
#
#   - 'workingctx._poststatusfixup()' (= 'repo.status()')
#   - 'committablectx.markcommitted()'
