add target method delegation
This patch replaces some code in the record targets with target method
delegation.
record-full.c stores pointers to many target methods when the record
target is pushed. Then it later delegates some calls via these. This
is wrong because it violates the target stack contract. In particular
it is ok to unpush a target at any stratum, but record-full does not
keep track of this, so it could potentially call into an unpushed
target.
This patch fixes the problem by using the newly-introduced generic
approach to target delegation for the methods in question.
