revset: reintroduce and experimental revset for update destination

The revset is not ready for prime time yet. However it is useful to have some
version of it exposed to help candidate users to play with it and provide
feedback on what we should aim at.

We add a small test to make sure the code runs.

gethgversion() {
    make clean
    make local || make local PURE=--pure
    HG="$PWD/hg"

    $HG version > /dev/null || { echo 'abort: hg version failed!'; exit 1 ; }

    hgversion=`$HG version | sed -ne 's/.*(version \(.*\))$/\1/p'`

    if echo $hgversion | grep -- '-' > /dev/null 2>&1; then
        # nightly build case, version is like 1.3.1+250-20b91f91f9ca
        version=`echo $hgversion | cut -d- -f1`
        release=`echo $hgversion | cut -d- -f2 | sed -e 's/+.*//'`
    else
        # official tag, version is like 1.3.1
        version=`echo $hgversion | sed -e 's/+.*//'`
        release='0'
    fi
