lazyindex: speed up __getitem__

This function is fairly performance sensitive, so we make a couple
ugly tweaks:

- keep all entries packed so we needn't test entry types
- fold index lookup/load into unpack call to eliminate
  local variable setting

mkdir t
cd t
hg init
echo 0 > a
echo 0 > b
hg ci -A -m m -d "1000000 0"
hg rm a
hg cat a
sleep 1 # make sure mtime is changed
echo 1 > b
hg ci -m m -d "1000000 0"
echo 2 > b
hg cat -r 0 a
hg cat -r 0 b
hg cat -r 1 a
hg cat -r 1 b
