dirstate: add a C implementation for nonnormalentries
Before this patch, there was only a python version of nonnormalentries.
On mozilla-central we have a 10x win by putting this function in C:
% python -m timeit -s \
'from mercurial import hg, ui, parsers; \
repo = hg.repository(ui.ui(), "mozilla-central"); \
m = repo.dirstate._map' \
'parsers.nonnormalentries(m)'
100 loops, best of 3: 3.15 msec per loop
The python implementation runs in 31ms, a similar test gives:
10 loops, best of 3: 31.7 msec per loop
On our big repos, the win is still of 10x with the python implementation running
in 350ms and the C implementation running in 30ms.
