txnutil: factor out the logic to read file in according to HG_PENDING

This patch adds new file txnutil.py, because:

  - transaction.py is too large to import small utility logic
  - scmutil.py or so causes cyclic importing in phases.py

mayhavepending() is defined separately for convenience in subsequent
patch.
