changelog: lazily parse date/extra field
This is probably the most complicated patch in the parsing
refactor.
Because the date and extras are encoded in the same field, we
stuff the entire field into a dedicated variable and add a
property for accessing the sub-components of each. There is
some duplicated code here. But the code is relatively simple,
so it shouldn't be a big deal.
We see revset performance wins across the board:

We see a speed-up on revsets accessing date and extras because the new
parsing code only parses what you access. Even though they are stored
the same text field, we avoid parsing dates when accessing extras and
vice-versa.
But strangely revsets accessing both date and extras appeared to speed
up as well! I'm not sure if this is due to refactoring the parsing
code or due to an optimization in revsets. You can't argue with the
results!
