manifest: use custom C implementation of lazymanifest

This version is actually lazy, unlike the pure-python version. The
latter could stand to be optimized if anyone actually wants to use it
seriously. I put no work into it.

Before any of my related changes on mozilla-central:

perfmanifest tip
! wall 0.268805 comb 0.260000 user 0.260000 sys 0.000000 (best of 37)
perftags
! result: 162
! wall 0.007099 comb 0.000000 user 0.000000 sys 0.000000 (best of 401)
perfstatus
! wall 0.415680 comb 0.420000 user 0.260000 sys 0.160000 (best of 24)
hgperf export tip
! wall 0.142118 comb 0.140000 user 0.140000 sys 0.000000 (best of 67)

after all of my changes on mozilla-central:

./hg:
perfmanifest tip
! wall 0.232640 comb 0.230000 user 0.220000 sys 0.010000 (best of 43)
perftags
! result: 162
! wall 0.007057 comb 0.010000 user 0.000000 sys 0.010000 (best of 395)
perfstatus
! wall 0.415503 comb 0.420000 user 0.280000 sys 0.140000 (best of 24)
hgperf export tip
! wall 0.025096 comb 0.030000 user 0.030000 sys 0.000000 (best of 102)

so it's no real change in performance on perf{manifest,tags,status},
but is a huge win on 'hgperf export tip'.

There's a little performance work that could still be done here:
fastdelta() could be done significantly more intelligently by using
the internal state of the lazymanifest type in C, but that seems like
good future work.

This tests if CGI files from before d0db3462d568 still work.
