This adds a "self" argument to to_supports_btrace. Due to how one
implementation of this method is shared with gdbserver this required a
small change to gdbserver as well.

* target.h (struct target_ops) <supports_btrace>: Add target_ops
argument.
(target_supports_btrace): Update.
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.

This patch adds a new script, call make-target-delegates, which
auto-generates some target delegation code based on annotations in
target.h. This adds the new delegation macros, the new generated
file, and adds the necessary calls to the new generated functions to
target.c. It doesn't, however, add any actual annotations to the
target methods, leaving these for separate patches.
