dirstate: call the C implementation of nonnonormalentries when available

Before this patch, we were using python code for computing the nonnormal
dirstate entries. This patch makes us use the C implementation of the function
when it is available.

Using the nonnormal set in hgwatchman improves hg status performance. Below
are the numbers for mozilla-central.

with the changes:
$ hg perfstatus
    ! wall 0.010632 comb 0.000000 user 0.000000 sys 0.000000 (best of 246)

without the changes:
$ hg perfstatus
    ! wall 0.036442 comb 0.030000 user 0.030000 sys 0.000000 (best of 100)

On mozilla-central the improvement to hg status is ~20% (0.25s to 0.2s),
on our big repos at Facebook, the win is ~40% (1.2s to 0.72s).
