templatekw: add a {negrev} keyword

Revision numbers are getting much maligned for two reasons: they are
too long in large repos and users get confused by their local-only
nature. It just occurred to me that negative revision numbers avoid
both of those problems. Since negative revision numbers change
whenever the repo changes, it's much more obvious that they are a
local-only convenience. Additionally, for the recent commits that we
usually care about the most, negative revision numbers are always near
zero.

This commit adds a negrev templatekw to more easily expose negative
revision numbers. It's not easy to reliably produce this output with
existing keywords due to hidden commits while at the same time
ensuring good performance.

# TODO there are a few deficiencies in this file:
# * The "namespace" of the labels needs to be worked out. We currently
#   piggyback on existing values so color works.
