Andrew Burgess 51a948fdf0 gdb: Have allocate_target_description return a unique_ptr 
Update allocate_target_description to return a target_desc_up, a
specialisation of unique_ptr.

This commit does not attempt to make use of the unique_ptr in the
best possible way, in almost all cases we immediately release the
pointer from within the unique_ptr and then continue as before.

There are a few places where it was easy to handle the unique_ptr, and
in these cases I've done that.

Everything under gdb/features/* is auto-regenerated.

There should be no user visible changes after this commit.

	unique_ptr returned from allocate_target_description.
