convert to_supports_btrace

Browse Source 
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.

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* common/linux-btrace.c (linux_supports_btrace): Add "ops"
	argument.
	* common/linux-btrace.h (linux_supports_btrace): Update.
	* remote.c (remote_supports_btrace): Add "self" argument.
	* target-delegates.c: Rebuild.
	* target.c (target_supports_btrace): Remove.
	* target.h (struct target_ops) <to_supports_btrace>: Add
	target_ops argument.
	(target_supports_btrace): New define.

2014-02-19  Tom Tromey  <tromey@redhat.com>

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