Add APIs to get BPF program function name, as opposed to bpf_program__title(), which returns BPF program function's section name. Function name has a benefit of being a valid C identifier and uniquely identifies a specific BPF program, while section name can be duplicated across multiple independent BPF programs. Add also bpf_object__find_program_by_name(), similar to bpf_object__find_program_by_title(), to facilitate looking up BPF programs by their C function names. Convert one of selftests to new API for look up.

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.
