revert: Rename no_replay to record_origin

The "-x" command-line option is used to record the name of the
original commits being picked in the commit message.  The variable
corresponding to this option is named "no_replay" for historical
reasons; the name is especially confusing because the term "replay" is
used to describe what cherry-pick does (for example, in the
documentation of the "--mainline" option).  So, give the variable
corresponding to the "-x" command-line option a better name:
"record_origin".
