Subject: [PATCH] rebuild codes with configure --enable-regen-codes (new
 option)

add --enable-regen-codes configure option which is used to control
invocations of `make codes`

Previously these were controlled by --enable-developer, but having it as
a separate option is useful too. The default is 'yes' when --enable-developer
is given too.
