To prepare for impending deprecation of libbpf's bpf_program__get_prog_info_linear, migrate uses of this function to use bpf_obj_get_info_by_fd. Since the profile_target_name and dump_prog_id_as_func_ptr helpers were only looking at the first func_info, avoid grabbing the rest to save a malloc. For do_dump, add a more full-featured helper, but avoid free/realloc of buffer when possible for multi-prog dumps.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
