annotate: do not construct attr.s object per line while computing history
Unfortunately, good abstraction has a cost. It's way slower to construct
an annotateline() object than creating a plain tuple or a list. This patch
changes the internal data structure from row-based to columnar, so the
decorate() function can be instant (i.e. no Python in hot loop.)
For code readability, the outermost tuple is switched to an attr.s object
instead.
(original, row-based attr.s)
$ hg annot mercurial/commands.py --time > /dev/null
time: real 11.470 secs (user 11.400+0.000 sys 0.070+0.000)
$ hg annot mercurial/commands.py --time --line-number > /dev/null
time: real 39.590 secs (user 39.500+0.000 sys 0.080+0.000)
(this patch, columnar)

$ hg annot mercurial/commands.py --time --line-number > /dev/null
time: real 12.240 secs (user 12.170+0.000 sys 0.090+0.000)
(cf. 4.3.3, row-based tuple)
