templatekw: allow getlatesttags() to match a specific tag pattern

This will allow the latest class of tag to be found, such as a release candidate
or final build, instead of just the absolute latest.  It will be exposed in a
future patch.

It's unfortunate that the original 'latesttags' cache can't be used to determine
the proper values, but it isn't fully populated for the entire repo.  For
example, the {latesttagdistance} keyword on the Mecurial repo builds the cache
up back to the revision for 1.4.  If the pattern was 're:^0\.\d$', that wouldn't
be in the cache.  Maybe this can be optimized some other way, but for now, this
is the simpliest implementation.

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
}
