revset: extract parsing logic out of formatspec

We want to be able to perform better handling of some input when running
revset (eg: `repo.revs("%ld", somerevs)`). The first step is to be able to
access some of the parsed content before it gets substituted. There are many
possible different substitutions, we'll add support for them gradually.

In this changeset we support none, we just split some logic in a sub function
as a preparatory step.

In this test, we want to test LFS bundle application on both LFS and non-LFS
repos.

To make it more interesting, the file revisions will contain hg filelog
metadata ('\1\n'). The bundle will have 1 file revision overlapping with the
destination repo.

#  rev      1          2         3
#  repo:    yes        yes       no
#  bundle:  no (base)  yes       yes (deltabase: 2 if possible)

It is interesting because rev 2 could have been stored as LFS in the repo, and
non-LFS in the bundle; or vice-versa.

Init

  $ cat >> $HGRCPATH << EOF

  > EOF

Helper functions

  $ commitxy() {
  > hg debugdrawdag "$@" <<'EOS'
  >  Y  # Y/X=\1\nAAAA\nE\nF
  >  |  # Y/Y=\1\nAAAA\nG\nH
  >  X  # X/X=\1\nAAAA\nC\n
  >     # X/Y=\1\nAAAA\nD\n

  $ commitz() {

  $ enablelfs() {

Generate bundles

  $ for i in normal lfs; do
  >   NAME=src-$i
  >   hg init $TESTTMP/$NAME
  >   cd $TESTTMP/$NAME
  >   [ $i = lfs ] && enablelfs
  >   commitxy
  >   commitz
  >   hg bundle -q --base X -r Y+Z $TESTTMP/$NAME.bundle
  >   SRCNAMES="$SRCNAMES $NAME"
  > done

Prepare destination repos

  $ for i in normal lfs; do
  >   NAME=dst-$i
  >   hg init $TESTTMP/$NAME
  >   cd $TESTTMP/$NAME
  >   [ $i = lfs ] && enablelfs
  >   commitxy
  >   DSTNAMES="$DSTNAMES $NAME"
  > done

Apply bundles

  $ for i in $SRCNAMES; do
  >   for j in $DSTNAMES; do
  >     echo ---- Applying $i.bundle to $j ----
  >     cp -R $TESTTMP/$j $TESTTMP/tmp-$i-$j
  >     cd $TESTTMP/tmp-$i-$j
  >     if hg unbundle $TESTTMP/$i.bundle -q 2>/dev/null; then
  >       hg verify -q && echo OK
  >     else
  >       echo CRASHED
  >     fi
  >   done
  > done
