obsolete: use parsers.fm1readmarker if it exists for a ~38% perf win
This moves perfloadmarkers on my linux workstation (63494 markers from
mpm, crew, and myself) performance from
! wall 0.357657 comb 0.360000 user 0.350000 sys 0.010000 (best of 28)
to
! wall 0.222345 comb 0.220000 user 0.210000 sys 0.010000 (best of 41)
which is a pretty good improvement.
On my BSD machine, which is ancient and slow, before:
! wall 3.584964 comb 3.578125 user 3.539062 sys 0.039062 (best of 3)
after:
! wall 2.267974 comb 2.265625 user 2.195312 sys 0.070312 (best of 5)
I feel like we could do better by moving the whole generator function
into C, but I didn't want to tackle that right away.

Additional tricky linkrev case
------------------------------
If the first file revision after the diff base has a linkrev pointing to a
changeset on another branch with a revision lower that the diff base, we can
jump past the copy detection limit and fail to detect the rename.
$ hg init diffstoplinkrev
$ cd diffstoplinkrev
$ touch f
$ hg ci -Aqm 'empty f'
Make a simple change
$ echo change > f
$ hg ci -m 'change f'
Make a second branch, we use a named branch to create a simple commit
that does not touch f.
$ hg up -qr 'desc(empty)'
$ hg branch -q dev
$ hg ci -Aqm dev
Graft the initial change, as f was untouched, we reuse the same entry and the
linkrev point to the older branch.
$ hg graft -q 'desc(change)'
Make a rename because we want to track renames. It is also important that the
faulty linkrev is not the "start" commit to ensure the linkrev will be used.
$ hg mv f renamed
$ hg ci -m renamed
$ hg log -G -T '{rev} {desc}'
@ 4 renamed
|
o 3 change f
|
o 2 dev
|
| o 1 change f
|/
o 0 empty f
The copy tracking should still reach rev 2 (branch creation).
accessing the parent of 4 (renamed) should not jump use to revision 1.
