dirs: fix out-of-bounds access in Py3
The hack for mutating Python's variable-length integers that was
ported to py3 in
cb3048746dae (dirs: port PyInt code to work on Python
3, 2016-10-08) was reading from ob_digit[1] instead of ob_digit[0] for
some reason. Space for ob_digit[1] would only be allocated for
integers larger than 30 bits, so we ended up writing to unallocated
memory. Also, we would write an integer that's 2^30 times too large,
so we would never free these integers.

Function to test discovery between two repos in both directions, using both the local shortcut
(which is currently not activated by default) and the full remotable protocol:
$ testdesc() { # revs_a, revs_b, dagdesc
> if [ -d foo ]; then rm -rf foo; fi
> hg init foo
> cd foo
> hg debugbuilddag "$3"
> hg clone . a $1 --quiet
> hg clone . b $2 --quiet
> echo
> echo "% -- a -> b tree"
> hg -R a debugdiscovery b --verbose --old
> echo
> echo "% -- a -> b set"
> hg -R a debugdiscovery b --verbose --debug --config progress.debug=true
> echo
> echo "% -- a -> b set (tip only)"
> hg -R a debugdiscovery b --verbose --debug --config progress.debug=true --rev tip
> echo
> echo "% -- b -> a tree"
> hg -R b debugdiscovery a --verbose --old
> echo
> echo "% -- b -> a set"
> hg -R b debugdiscovery a --verbose --debug --config progress.debug=true
> echo
> echo "% -- b -> a set (tip only)"
> hg -R b debugdiscovery a --verbose --debug --config progress.debug=true --rev tip
