splicemap: improve error handling when source is hg (issue2084)

1. Introduced 2 levels of error handling for splicemap files
   a. Check the splicemap file for rules which are same across different
      types of source repos.  This is done through enhancing parsesplicemap
      function
   b. Check revision string formats.  Each repo may have their own format.
      This is done usign checkrevformat function
   c. Implemented the above two for hg

  $ check_code="$TESTDIR"/../contrib/check-code.py
  $ cd "$TESTDIR"/..
  $ if hg identify -q > /dev/null 2>&1; then :
  > else
  >     echo "skipped: not a Mercurial working dir" >&2
  >     exit 80
  > fi

New errors are not allowed. Warnings are strongly discouraged.

  $ hg manifest 2>/dev/null \
  >   | xargs "$check_code" --warnings --nolineno --per-file=0 \
  >   || false

Check Python files without py extension

  >   "$TESTTMP"/
  $ for f in "$TESTTMP"/*; do cp "$f" "$f.py"; done
  $ "$check_code" --warnings --nolineno --per-file=0 "$TESTTMP"/*.py \
  >   || false
