Simplify the function pristine_transfer() by avoiding the use of a recursive
call and instead using a separate function. This is a precursor to
simplifying the way parameters are passed in.

* subversion/libsvn_wc/wc_db_pristine.c
  (pristine_transfer): Rename to 'pristine_transfer_txn2'. Move the
    first-time-through code path out of here ...
  (pristine_transfer_txn1): ... into this new function.
  (svn_wc__db_pristine_transfer): Call pristine_transfer_txn1() instead of
    pristine_transfer().
