reachableroots: use internal "revstates" array to test if rev is a root

The main goal of this patch series is to reduce the use of PyXxx() function
that is likely to require ugly error handling and inc/decref. Plus, this is
faster than using PySet_Contains().

  revset #0: 0::tip
  0) 0.004168
  1) 0.003678  88%

This patch ignores out-of-range roots as they are in the pure implementation.
Because reachable sets are calculated from heads, and out-of-range heads raise
IndexError, we can just take out-of-range roots as unreachable. Otherwise,
the test of "hg log -Gr '. + wdir()'" would fail.

"heads" argument is changed to a list. Should we have to rename the C function
as its signature is changed?

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
}
